Class ExceptionTable

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).

private int number_of_exceptions

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, ConstantPool constant_pool)

Parameters: name_index Index in constant pool length Content length in bytes exception_index_table Table of indices in constant pool constant_pool Array of constants

ExceptionTable

ExceptionTable(int name_index, int length, DataInputStream file, ConstantPool constant_pool)

Construct object from file stream.

Parameters: name_index Index in constant pool length Content length in bytes file Input stream constant_pool Array of constants

Throws: IOException

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.

Parameters: v Visitor object

copy

public Attribute copy(ConstantPool _constant_pool)

Returns: deep copy of this attribute

dump

public final void dump(DataOutputStream file)

Dump exceptions attribute to file stream in binary format.

Parameters: file Output file stream

Throws: IOException
