Constructor Detail

SourceFile

public SourceFile(SourceFile c)

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

SourceFile

public SourceFile(int name_index,
                  int length,
                  int sourcefile_index,
                  ConstantPool constant_pool)

Parameters:

name_index - Index in constant pool to CONSTANT_Utf8

length - Content length in bytes

constant_pool - Array of constants

sourcefile_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.

Overrides:

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

getSourceFileIndex

public final int getSourceFileIndex()

Returns:

Index in constant pool of source file name.

setSourceFileIndex

public final void setSourceFileIndex(int sourcefile_index)

Parameters:

sourcefile_index. -

getSourceFileName

public final java.lang.String getSourceFileName()

Returns:

Source file name.

toString

public final java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation

copy

public Attribute copy(ConstantPool constant_pool)

Overrides:

copy in class Attribute

Returns:

deep copy of this attribute
