The numeric value of this symbol. This is:

• the symbol's value for CONSTANT_INTEGER_TAG,CONSTANT_FLOAT_TAG, CONSTANT_LONG_TAG, CONSTANT_DOUBLE_TAG,
• the CONSTANT_MethodHandle_info reference_kind field value for CONSTANT_METHOD_HANDLE_TAG symbols,
• the CONSTANT_InvokeDynamic_info bootstrap_method_attr_index field value for CONSTANT_INVOKE_DYNAMIC_TAG symbols,
• the offset of a bootstrap method in the BootstrapMethods boostrap_methods array, for CONSTANT_DYNAMIC_TAG or BOOTSTRAP_METHOD_TAG symbols,
• the bytecode offset of the NEW instruction that created an Frame#ITEM_UNINITIALIZED type for UNINITIALIZED_TYPE_TAG symbols,
• the indices (in the class' type table) of two TYPE_TAG source types for MERGED_TYPE_TAG symbols,
• 0 for the other types of symbol.

The index of this symbol in the constant pool, in the BootstrapMethods attribute, or in the (ASM specific) type table of a class (depending on the tag value).

Additional information about this symbol, generally computed lazily. Warning: the value of this field is ignored when comparing Symbol instances (to avoid duplicate entries in a SymbolTable). Therefore, this field should only contain data that can be computed from the other fields of this class. It contains:

• the Type#getArgumentsAndReturnSizes of the symbol's method descriptor for CONSTANT_METHODREF_TAG, CONSTANT_INTERFACE_METHODREF_TAG and CONSTANT_INVOKE_DYNAMIC_TAG symbols,
• the index in the InnerClasses_attribute 'classes' array (plus one) corresponding to this class, for CONSTANT_CLASS_TAG symbols,
• the index (in the class' type table) of the merged type of the two source types for MERGED_TYPE_TAG symbols,
• 0 for the other types of symbol, or if this field has not been computed yet.

The tag value of a merged type entry in the (ASM specific) type table of a class.

The name of the class field or method corresponding to this symbol. Only used for CONSTANT_FIELDREF_TAG, CONSTANT_METHODREF_TAG, CONSTANT_INTERFACE_METHODREF_TAG, CONSTANT_NAME_AND_TYPE_TAG, CONSTANT_METHOD_HANDLE_TAG, CONSTANT_DYNAMIC_TAG and CONSTANT_INVOKE_DYNAMIC_TAG symbols.

The internal name of the owner class of this symbol. Only used for CONSTANT_FIELDREF_TAG, CONSTANT_METHODREF_TAG, CONSTANT_INTERFACE_METHODREF_TAG, and CONSTANT_METHOD_HANDLE_TAG symbols.

A tag indicating the type of this symbol. Must be one of the static tag values defined in this class.

The tag value of a normal type entry in the (ASM specific) type table of a class.

The tag value of an Frame#ITEM_UNINITIALIZED type entry in the type table of a class.

The string value of this symbol. This is:

• a field or method descriptor for CONSTANT_FIELDREF_TAG, CONSTANT_METHODREF_TAG, CONSTANT_INTERFACE_METHODREF_TAG, CONSTANT_NAME_AND_TYPE_TAG, CONSTANT_METHOD_HANDLE_TAG, CONSTANT_METHOD_TYPE_TAG, CONSTANT_DYNAMIC_TAG and CONSTANT_INVOKE_DYNAMIC_TAG symbols,
• an arbitrary string for CONSTANT_UTF8_TAG and CONSTANT_STRING_TAG symbols,
• an internal class name for CONSTANT_CLASS_TAG, TYPE_TAG and UNINITIALIZED_TYPE_TAG symbols,
• null for the other types of symbol.

Constructs a new Symbol. This constructor can't be used directly because the Symbol class is abstract. Instead, use the factory methods of the SymbolTable class.

Parameters

index:int

the symbol index in the constant pool, in the BootstrapMethods attribute, or in the (ASM specific) type table of a class (depending on 'tag').

tag:int

the symbol type. Must be one of the static tag values defined in this class.

owner:String

The internal name of the symbol's owner class. Maybe null.

name:String

The name of the symbol's corresponding class field or method. Maybe null.

value:String

The string value of this symbol. Maybe null.

data:long

The numeric value of this symbol.

Returns the result Type#getArgumentsAndReturnSizes on value.

Returns:int

the result Type#getArgumentsAndReturnSizes on value (memoized in info for efficiency). This should only be used for CONSTANT_METHODREF_TAG, CONSTANT_INTERFACE_METHODREF_TAG and CONSTANT_INVOKE_DYNAMIC_TAG symbols.
