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 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.

isActualParameterList

public static final boolean isActualParameterList(String s)

isFormalParameterList

public static final boolean isFormalParameterList(String s)

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)
