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

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

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.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException

Dump source file attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

java.io.IOException

getSignatureIndex

public final int getSignatureIndex()

Returns:

Index in constant pool of source file name.

setSignatureIndex

public final void setSignatureIndex(int signature_index)

getSignature

public final java.lang.String getSignature()

Returns:

GJ signature.

translate

public static java.lang.String translate(java.lang.String s)

isFormalParameterList

public static final boolean isFormalParameterList(java.lang.String s)

isActualParameterList

public static final boolean isActualParameterList(java.lang.String s)

toString

public final java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation

copy

public Attribute copy(ConstantPool constant_pool)

Specified by:

copy in class Attribute

Returns:

deep copy of this attribute
