<!-- ##### SECTION Title ##### -->
Constant pool
<!-- ##### SECTION Short_Description ##### -->
Constant pool structures and operations.
<!-- ##### SECTION Long_Description ##### -->
<para>
The constant pool is a table in each class that contains the values for
all constants.
Typically any reference to a constant anywhere in a class
file is using the index of that constant in the table.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
</para>
<!-- ##### ENUM ConstantTag ##### -->
<para>
Tag value for constant pool entries.
</para>
@CONSTANT_Empty: Empty.
@CONSTANT_Utf8: UTF-8 string.
@CONSTANT_Integer: Integer.
@CONSTANT_Float: float.
@CONSTANT_Long: long.
@CONSTANT_Double: double.
@CONSTANT_Class: reference to a class/interface.
@CONSTANT_String: reference to a string.
@CONSTANT_Fieldref: reference to a field.
@CONSTANT_Methodref: reference to a method.
@CONSTANT_InterfaceMethodref: a reference to an interface method.
@CONSTANT_NameAndType: name and type information.
<!-- ##### ENUM IntType ##### -->
<para>
Specifies the type for constants which are internally promoted to int.
</para>
@INT_IS_INT: int.
@INT_IS_BOOLEAN: boolean.
@INT_IS_CHAR: char.
@INT_IS_SHORT: short.
@INT_IS_BYTE: byte.
<!-- ##### STRUCT ClassEntry ##### -->
<para>
Constant pool entry for a class reference.
The tag value for this entry is %CONSTANT_Class.
</para>
@name_index:
<!-- ##### STRUCT ReferenceEntry ##### -->
<para>
Constant pool entry for a field, method or interface method reference.
Tag values for this type of entries are
%CONSTANT_Fieldref for fields,
%CONSTANT_Methodref for methods
and %CONSTANT_InterfaceMethodref for interface methods.
</para>
@class_index:
@name_and_type_index:
<!-- ##### STRUCT StringEntry ##### -->
<para>
Constant pool entry for a string reference.
The tag value for this entry is %CONSTANT_String.
</para>
@string_index:
<!-- ##### STRUCT IntegerEntry ##### -->
<para>
Constant pool entry for an integer or a float. Tag values for this type of
entries are %CONSTANT_Integer for integers and %CONSTANT_Float for floats.
</para>
@bytes:
<!-- ##### STRUCT LongEntry ##### -->
<para>
Constant pool entry for a long or double.
Tag values for this type of entries
are %CONSTANT_Long for longs and %CONSTANT_Double for doubles.
<note>The next entry in the constant pool after each long/double
is reserved for the VM. That extra entry is counted even though it
is not physically present in the file.
</note>
</para>
@long_bytes:
<!-- ##### STRUCT NameAndTypeEntry ##### -->
<para>
Constant pool entry for name and type information.
The tag value for this entry is %CONSTANT_NameAndType.
</para>

@descriptor_index:
<!-- ##### STRUCT UTF8Entry ##### -->
<para>
Constant pool entry for UTF-8 data.
The tag value for this entry is %CONSTANT_Utf8
</para>
@length:
@contents:
<!-- ##### STRUCT ConstantPoolEntry ##### -->
<para>
Constant pool entry.
</para>
@tag:
<!-- ##### STRUCT ConstantPool ##### -->
<para>
The Constant Pool.
The number of entries also includes some entries that are reserved for
the runtime environment and are not physically present in the file.
Those entries are marked with a tag of %CONSTANT_Empty.
