Field Detail

signature_index

private int signature_index

Constructor Detail

Signature

public Signature(Signature c)

Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

Signature

Signature(int name_index, int length, DataInputStream file, ConstantPool constant_pool)

Construct object from file stream.

Parameters: name_index Index in constant pool to CONSTANT_Utf8 length Content length in bytes file Input stream constant_pool Array of constants

Throws: IOException

Signature

public Signature(int name_index, int length, int signature_index, ConstantPool constant_pool)

Parameters: name_index Index in constant pool to CONSTANT_Utf8 length Content length in bytes signature_index Index in constant pool to CONSTANT_Utf8 constant_pool Array of constants

Method Detail

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Parameters: v Visitor object

copy

public Attribute copy(ConstantPool _constant_pool)

Returns: deep copy of this attribute

dump

public final void dump(DataOutputStream file)

Dump source file attribute to file stream in binary format.

Parameters: file Output file stream

Throws: IOException
