Constructor Detail

ExceptionTable

public ExceptionTable(ExceptionTable c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() 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
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
Overrides:
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.
Parameters:
file - Output file stream
Overrides:
dump in class Attribute

getExceptionIndexTable

public final int[] getExceptionIndexTable()
Returns:
Array of indices into constant pool of thrown exceptions.

getNumberOfExceptions

public final int getNumberOfExceptions()
Returns:
Length of exception table.

getExceptionNames

public final java.lang.String[] getExceptionNames()
Returns:
class names of thrown exceptions

setExceptionIndexTable

public final void setExceptionIndexTable(int[] exception_index_table)
Parameters:
exception_index_table. - Also redefines number_of_exceptions according to table length.

toString

public final java.lang.String toString()
Returns:
String representation, i.e. a list of thrown exceptions.
Overrides:
toString in class Attribute

copy

public Attribute copy(ConstantPool constant_pool)
Returns:
deep copy of this attribute
Overrides:
copy in class Attribute
