                       int length,

                ConstantPool constant_pool)
          throws java.io.IOException
Construct object from file stream.

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.

Specified by:
accept in interface Node
Specified by:
accept in class Attribute

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException
Dump line number table attribute to file stream in binary format.

Overrides:
dump in class Attribute

getLineNumberTable

public final LineNumber[] getLineNumberTable()

setLineNumberTable

public final void setLineNumberTable(LineNumber[] line_number_table)

toString

public final java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in class Attribute

getSourceLine

public int getSourceLine(int pos)
Map byte code positions to source code lines.


copy

public Attribute copy(ConstantPool _constant_pool)
Specified by:
copy in class Attribute

getTableLength

public final int getTableLength()
