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
Signature_index - Index in constant pool to CONSTANT_Utf8
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
Overrides:
accept in class Attribute

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException
Dump source file attribute to file stream in binary format.
Parameters:
file - Output file stream
Overrides:
dump in class Attribute

getSignatureIndex

public final int getSignatureIndex()
Returns:
Index in constant pool of source file name.

setSignatureIndex

public final void setSignatureIndex(int signature_index)
Parameters:
Signature_index. -  

getSignature

public final java.lang.String getSignature()
Returns:
GJ signature.

toString

public final java.lang.String toString()
Returns:
String representation
Overrides:
toString in class Attribute

copy

public Attribute copy(ConstantPool constant_pool)
Returns:
deep copy of this attribute
Overrides:
copy in class Attribute
