Constructor Details

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

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

Method Details

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
Overrides:
accept in interface Attribute
Parameters:
v - Visitor object

copy

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

dump

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

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:

toString

public final String toString()
Overrides:
toString in interface Attribute
Returns:
String representation

translate

public static String translate(String s)
