Class SourceFile

java.lang.Object

org.aspectj.apache.bcel.classfile.Attribute

org.aspectj.apache.bcel.classfile.SourceFile

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Node

public final class SourceFile
extends Attribute

This class is derived from Attribute and represents a reference to the source file of this class. At most one SourceFile attribute should appear per classfile. The intention of this class is that it is instantiated from the Attribute.readAttribute() method.

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, which should represent the string "SourceFile".

length - Content length in bytes, the value should be 2.

constant_pool - The constant pool that this attribute is associated with.

sourcefile_index - Index in constant pool to CONSTANT_Utf8. This string will be interpreted as the name of the file from which this class was compiled. It will not be interpreted as indicating the name of the directory contqining the file or an absolute path; this information has to be supplied the consumer of this attribute - in many cases, the JVM.

Method Detail

accept

public void accept(ClassVisitor 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 source file attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

java.io.IOException

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
