public final class ExceptionTable
extends Attribute

This class represents the table of exceptions that are thrown by a method. This attribute may be used once per method. The name of this class is ExceptionTable for historical reasons; The Java Virtual Machine Specification, Second Edition defines this attribute using the name Exceptions (which is inconsistent with the other classes).

Constructor Detail

ExceptionTable

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


ExceptionTable

public ExceptionTable(int name_index,
                      int length,
                      int[] exception_index_table,

ExceptionTable

ExceptionTable(int name_index,
               int length,
               java.io.DataInputStream file,
               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 exceptions attribute to file stream in binary format.

Overrides:
dump in class Attribute

getExceptionIndexTable

public final int[] getExceptionIndexTable()

getNumberOfExceptions

public final int getNumberOfExceptions()

getExceptionNames

public final java.lang.String[] getExceptionNames()

setExceptionIndexTable

public final void setExceptionIndexTable(int[] exception_index_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

copy

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