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

getSignature

public final String getSignature()

Returns: GJ signature.

getSignatureIndex

public final int getSignatureIndex()

Returns: Index in constant pool of source file name.

identStart

private static boolean identStart(int ch)

isActualParameterList

public static final boolean isActualParameterList(String s)

isFormalParameterList

public static final boolean isFormalParameterList(String s)

matchGJIdent

private static final void matchGJIdent(Signature.MyByteArrayInputStream in, StringBuffer buf)

matchIdent

private static final void matchIdent(Signature.MyByteArrayInputStream in, StringBuffer buf)

setSignatureIndex

public final void setSignatureIndex(int signature_index)

Parameters: signature_index the index info the constant pool of this signature

toString

public final String toString()

Returns: String representation

translate

public static String translate(String s)
