Language
========
.. currentmodule:: graphql.language
.. automodule:: graphql.language
:no-members:

AST
---
.. autoclass:: Location
.. autoclass:: Node
Each kind of AST node has its own class:
.. autoclass:: ArgumentNode
.. autoclass:: BooleanValueNode
.. autoclass:: ConstArgumentNode
.. autoclass:: ConstDirectiveNode
.. autoclass:: ConstListValueNode
.. autoclass:: ConstObjectFieldNode
.. autoclass:: ConstObjectValueNode
.. autoclass:: ConstValueNode
.. autoclass:: DefinitionNode
.. autoclass:: DirectiveDefinitionNode
.. autoclass:: DirectiveNode
.. autoclass:: DocumentNode
.. autoclass:: EnumTypeDefinitionNode
.. autoclass:: EnumTypeExtensionNode
.. autoclass:: EnumValueDefinitionNode
.. autoclass:: EnumValueNode
.. autoclass:: ExecutableDefinitionNode
.. autoclass:: FieldDefinitionNode
.. autoclass:: FieldNode
.. autoclass:: FloatValueNode
.. autoclass:: FragmentDefinitionNode
.. autoclass:: FragmentSpreadNode
.. autoclass:: InlineFragmentNode
.. autoclass:: InputObjectTypeDefinitionNode
.. autoclass:: InputObjectTypeExtensionNode
.. autoclass:: InputValueDefinitionNode
.. autoclass:: IntValueNode
.. autoclass:: InterfaceTypeDefinitionNode
.. autoclass:: InterfaceTypeExtensionNode
.. autoclass:: ListTypeNode
.. autoclass:: ListValueNode
.. autoclass:: NameNode
.. autoclass:: NamedTypeNode
.. autoclass:: NonNullTypeNode
.. autoclass:: NullValueNode
.. autoclass:: ObjectFieldNode
.. autoclass:: ObjectTypeDefinitionNode

.. autoclass:: OperationDefinitionNode
.. autoclass:: OperationType
.. autoclass:: OperationTypeDefinitionNode
.. autoclass:: ScalarTypeDefinitionNode
.. autoclass:: ScalarTypeExtensionNode
.. autoclass:: SchemaDefinitionNode
.. autoclass:: SchemaExtensionNode
.. autoclass:: SelectionNode
.. autoclass:: SelectionSetNode
.. autoclass:: StringValueNode
.. autoclass:: TypeDefinitionNode
.. autoclass:: TypeExtensionNode
.. autoclass:: TypeNode
.. autoclass:: TypeSystemDefinitionNode
.. autoclass:: TypeSystemExtensionNode
.. autoclass:: UnionTypeDefinitionNode
.. autoclass:: UnionTypeExtensionNode
.. autoclass:: ValueNode
.. autoclass:: VariableDefinitionNode
.. autoclass:: VariableNode
Directive locations are specified using the following enumeration:
.. autoclass:: DirectiveLocation
You can also check the type of nodes with the following predicates:
.. autofunction:: is_definition_node
.. autofunction:: is_executable_definition_node
.. autofunction:: is_selection_node
.. autofunction:: is_value_node
.. autofunction:: is_const_value_node
.. autofunction:: is_type_node
.. autofunction:: is_type_system_definition_node
.. autofunction:: is_type_definition_node
.. autofunction:: is_type_system_extension_node
.. autofunction:: is_type_extension_node
Lexer
-----
.. autoclass:: Lexer
.. autoclass:: TokenKind
.. autoclass:: Token
Location
--------
.. autofunction:: get_location
.. autoclass:: SourceLocation
.. autofunction:: print_location
.. autoclass:: FormattedSourceLocation
:no-inherited-members:
Parser
------
.. autofunction:: parse
.. autofunction:: parse_type
.. autofunction:: parse_value
.. autofunction:: parse_const_value
Printer
-------
.. autofunction:: print_ast
Source
------
.. autoclass:: Source
.. autofunction:: print_source_location
Visitor
-------
.. autofunction:: visit
.. autoclass:: Visitor
.. autoclass:: ParallelVisitor
The module also exports the following enumeration that can be used as the return type
for :class:`Visitor` methods:
.. currentmodule:: graphql.language.visitor
.. autoclass:: VisitorActionEnum
.. currentmodule:: graphql.language
The module also exports the values of this enumeration directly. These can be used as
return values of :class:`Visitor` methods to signal particular actions:
.. data:: BREAK
:annotation: (same as ``True``)
This return value signals that no further nodes shall be visited.
.. data:: SKIP
:annotation: (same as ``False``)
This return value signals that the current node shall be skipped.
.. data:: REMOVE
:annotation: (same as``Ellipsis``)
This return value signals that the current node shall be deleted.
.. data:: IDLE
:annotation: = None
This return value signals that no additional action shall take place.
