// For the UpdateItem operation, represents the attributes to be modified, the

// and then use PutItem to create a new item with new attributes. Attribute values
// cannot be null; string and binary type attributes must have lengths greater than
// zero; and set type attributes must not be empty. Requests with empty values will
// be rejected with a ValidationException exception.
type AttributeValueUpdate struct {

	// Specifies how to perform the update. Valid values are PUT (default), DELETE ,
	// and ADD . The behavior depends on whether the specified primary key already
	// exists in the table. If an item with the specified Key is found in the table:
	//   - PUT - Adds the specified attribute to the item. If the attribute already
	//   exists, it is replaced by the new value.
	//   - DELETE - If no value is specified, the attribute and its value are removed
	//   from the item. The data type of the specified value must match the existing
	//   value's data type. If a set of values is specified, then those values are
	//   subtracted from the old set. For example, if the attribute value was the set
	//   [a,b,c] and the DELETE action specified [a,c] , then the final attribute value
	//   would be [b] . Specifying an empty set is an error.
	//   - ADD - If the attribute does not already exist, then the attribute and its
	//   values are added to the item. If the attribute does exist, then the behavior of
	//   ADD depends on the data type of the attribute:
	//   - If the existing attribute is a number, and if Value is also a number, then
	//   the Value is mathematically added to the existing attribute. If Value is a
	//   negative number, then it is subtracted from the existing attribute. If you use
	//   ADD to increment or decrement a number value for an item that doesn't exist
	//   before the update, DynamoDB uses 0 as the initial value. In addition, if you use
	//   ADD to update an existing item, and intend to increment or decrement an
	//   attribute value which does not yet exist, DynamoDB uses 0 as the initial
	//   value. For example, suppose that the item you want to update does not yet have
	//   an attribute named itemcount, but you decide to ADD the number 3 to this
	//   attribute anyway, even though it currently does not exist. DynamoDB will create
	//   the itemcount attribute, set its initial value to 0 , and finally add 3 to it.
	//   The result will be a new itemcount attribute in the item, with a value of 3 .
	//   - If the existing data type is a set, and if the Value is also a set, then the
	//   Value is added to the existing set. (This is a set operation, not mathematical
	//   addition.) For example, if the attribute value was the set [1,2] , and the ADD
	//   action specified [3] , then the final attribute value would be [1,2,3] . An
	//   error occurs if an Add action is specified for a set attribute and the attribute
	//   type specified does not match the existing set type. Both sets must have the
	//   same primitive data type. For example, if the existing data type is a set of
	//   strings, the Value must also be a set of strings. The same holds true for
	//   number sets and binary sets. This action is only valid for an existing
	//   attribute whose data type is number or is a set. Do not use ADD for any other
	//   data types.
	// If no item with the specified Key is found:
	//   - PUT - DynamoDB creates a new item with the specified primary key, and then
	//   adds the attribute.
	//   - DELETE - Nothing happens; there is no attribute to delete.
	//   - ADD - DynamoDB creates a new item with the supplied primary key and number
	//   (or set) for the attribute value. The only data types allowed are number, number
	//   set, string set or binary set.

	//   {"N":"6"} does not equal {"NS":["6", "2", "1"]} .
	//   - LE : Less than or equal. AttributeValueList can contain only one
	//   AttributeValue element of type String, Number, or Binary (not a set type). If
	//   an item contains an AttributeValue element of a different type than the one
	//   provided in the request, the value does not match. For example, {"S":"6"} does
	//   not equal {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2",
	//   "1"]} .
	//   - LT : Less than. AttributeValueList can contain only one AttributeValue of

	//   {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]} .
	//   - NOT_NULL : The attribute exists. NOT_NULL is supported for all data types,
	//   including lists and maps. This operator tests for the existence of an attribute,
	//   not its data type. If the data type of attribute " a " is null, and you
	//   evaluate it using NOT_NULL , the result is a Boolean true . This result is
	//   because the attribute " a " exists; its data type is not relevant to the
	//   NOT_NULL comparison operator.
	//   - NULL : The attribute does not exist. NULL is supported for all data types,
	//   including lists and maps. This operator tests for the nonexistence of an
	//   attribute, not its data type. If the data type of attribute " a " is null, and
	//   you evaluate it using NULL , the result is a Boolean false . This is because
	//   the attribute " a " exists; its data type is not relevant to the NULL
	//   comparison operator.
	//   - CONTAINS : Checks for a subsequence, or value in a set. AttributeValueList
	//   can contain only one AttributeValue element of type String, Number, or Binary
	//   (not a set type). If the target attribute of the comparison is of type String,
	//   then the operator checks for a substring match. If the target attribute of the
	//   comparison is of type Binary, then the operator looks for a subsequence of the
	//   target that matches the input. If the target attribute of the comparison is a
	//   set (" SS ", " NS ", or " BS "), then the operator evaluates to true if it
	//   finds an exact match with any member of the set. CONTAINS is supported for
	//   lists: When evaluating " a CONTAINS b ", " a " can be a list; however, " b "
	//   cannot be a set, a map, or a list.
	//   - NOT_CONTAINS : Checks for absence of a subsequence, or absence of a value in
	//   a set. AttributeValueList can contain only one AttributeValue element of type
	//   String, Number, or Binary (not a set type). If the target attribute of the
	//   comparison is a String, then the operator checks for the absence of a substring
	//   match. If the target attribute of the comparison is Binary, then the operator
	//   checks for the absence of a subsequence of the target that matches the input. If
	//   the target attribute of the comparison is a set (" SS ", " NS ", or " BS "),
	//   then the operator evaluates to true if it does not find an exact match with any
	//   member of the set. NOT_CONTAINS is supported for lists: When evaluating " a
	//   NOT CONTAINS b ", " a " can be a list; however, " b " cannot be a set, a map,
	//   or a list.
	//   - BEGINS_WITH : Checks for a prefix. AttributeValueList can contain only one

	//   - EQ : Equal. EQ is supported for all data types, including lists and maps.
	//   AttributeValueList can contain only one AttributeValue element of type String,
	//   Number, Binary, String Set, Number Set, or Binary Set. If an item contains an
	//   AttributeValue element of a different type than the one provided in the

	//   {"N":"6"} . Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]} .
	//   - NE : Not equal. NE is supported for all data types, including lists and
	//   maps. AttributeValueList can contain only one AttributeValue of type String,
	//   Number, Binary, String Set, Number Set, or Binary Set. If an item contains an
	//   AttributeValue of a different type than the one provided in the request, the
	//   value does not match. For example, {"S":"6"} does not equal {"N":"6"} . Also,
	//   {"N":"6"} does not equal {"NS":["6", "2", "1"]} .
	//   - LE : Less than or equal. AttributeValueList can contain only one
	//   AttributeValue element of type String, Number, or Binary (not a set type). If
	//   an item contains an AttributeValue element of a different type than the one
	//   provided in the request, the value does not match. For example, {"S":"6"} does
	//   not equal {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2",
	//   "1"]} .
	//   - LT : Less than. AttributeValueList can contain only one AttributeValue of
	//   type String, Number, or Binary (not a set type). If an item contains an
	//   AttributeValue element of a different type than the one provided in the
	//   request, the value does not match. For example, {"S":"6"} does not equal
	//   {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]} .
	//   - GE : Greater than or equal. AttributeValueList can contain only one

	//   an item contains an AttributeValue element of a different type than the one
	//   provided in the request, the value does not match. For example, {"S":"6"} does
	//   not equal {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2",
	//   "1"]} .
	//   - GT : Greater than. AttributeValueList can contain only one AttributeValue
	//   element of type String, Number, or Binary (not a set type). If an item contains
	//   an AttributeValue element of a different type than the one provided in the
	//   request, the value does not match. For example, {"S":"6"} does not equal
	//   {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]} .
	//   - NOT_NULL : The attribute exists. NOT_NULL is supported for all data types,
	//   including lists and maps. This operator tests for the existence of an attribute,
	//   not its data type. If the data type of attribute " a " is null, and you
	//   evaluate it using NOT_NULL , the result is a Boolean true . This result is
	//   because the attribute " a " exists; its data type is not relevant to the
	//   NOT_NULL comparison operator.
	//   - NULL : The attribute does not exist. NULL is supported for all data types,
	//   including lists and maps. This operator tests for the nonexistence of an
	//   attribute, not its data type. If the data type of attribute " a " is null, and
	//   you evaluate it using NULL , the result is a Boolean false . This is because
	//   the attribute " a " exists; its data type is not relevant to the NULL
	//   comparison operator.
	//   - CONTAINS : Checks for a subsequence, or value in a set. AttributeValueList
	//   can contain only one AttributeValue element of type String, Number, or Binary
	//   (not a set type). If the target attribute of the comparison is of type String,
	//   then the operator checks for a substring match. If the target attribute of the
	//   comparison is of type Binary, then the operator looks for a subsequence of the
	//   target that matches the input. If the target attribute of the comparison is a
	//   set (" SS ", " NS ", or " BS "), then the operator evaluates to true if it
	//   finds an exact match with any member of the set. CONTAINS is supported for
	//   lists: When evaluating " a CONTAINS b ", " a " can be a list; however, " b "
	//   cannot be a set, a map, or a list.
	//   - NOT_CONTAINS : Checks for absence of a subsequence, or absence of a value in
	//   a set. AttributeValueList can contain only one AttributeValue element of type
	//   String, Number, or Binary (not a set type). If the target attribute of the
	//   comparison is a String, then the operator checks for the absence of a substring
	//   match. If the target attribute of the comparison is Binary, then the operator
	//   checks for the absence of a subsequence of the target that matches the input. If
	//   the target attribute of the comparison is a set (" SS ", " NS ", or " BS "),
	//   then the operator evaluates to true if it does not find an exact match with any
	//   member of the set. NOT_CONTAINS is supported for lists: When evaluating " a
	//   NOT CONTAINS b ", " a " can be a list; however, " b " cannot be a set, a map,
	//   or a list.
	//   - BEGINS_WITH : Checks for a prefix. AttributeValueList can contain only one
	//   AttributeValue of type String or Binary (not a Number or a set type). The
	//   target attribute of the comparison must be of type String or Binary (not a
	//   Number or a set type).
	//   - IN : Checks for matching elements in a list. AttributeValueList can contain
	//   one or more AttributeValue elements of type String, Number, or Binary. These
	//   attributes are compared against an existing attribute of an item. If any
	//   elements of the input are equal to the item attribute, the expression evaluates
	//   to true.
	//   - BETWEEN : Greater than or equal to the first value, and less than or equal
	//   to the second value. AttributeValueList must contain two AttributeValue
	//   elements of the same type, either String, Number, or Binary (not a set type). A
	//   target attribute matches if the target value is greater than, or equal to, the
	//   first element and less than, or equal to, the second element. If an item
	//   contains an AttributeValue element of a different type than the one provided
	//   in the request, the value does not match. For example, {"S":"6"} does not
	//   compare to {"N":"6"} . Also, {"N":"6"} does not compare to {"NS":["6", "2",
	//   "1"]}
	ComparisonOperator ComparisonOperator

	// Causes DynamoDB to evaluate the value before attempting a conditional
	// operation:
	//   - If Exists is true , DynamoDB will check to see if that attribute value
	//   already exists in the table. If it is found, then the operation succeeds. If it
	//   is not found, the operation fails with a ConditionCheckFailedException .
	//   - If Exists is false , DynamoDB assumes that the attribute value does not

	//   valid and the operation succeeds. If the value is found, despite the assumption
	//   that it does not exist, the operation fails with a
	//   ConditionCheckFailedException .
	// The default setting for Exists is true . If you supply a Value all by itself,
	// DynamoDB assumes the attribute exists: You don't have to set Exists to true ,
	// because it is implied. DynamoDB returns a ValidationException if:
