- public final class ExceptionTable
- extends Attribute
Class is derived from Attribute and represents the table
of exceptions that are thrown by a method. This attribute is used
by the Code attribute.

ExceptionTable()
- Empty constructor, all attributes have to be defined via `setXXX'
methods.
-
ExceptionTable(ExceptionTable)

-
-
accept(Visitor)
- Called by objects that are traversing the nodes of the tree implicitely
defined by the contents of a Java class.
-
dump(DataOutputStream)
- Dump exceptions attribute to file stream in binary format.

ExceptionTable
public ExceptionTable()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
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(short name_index,
int length,
short 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
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(DataOutputStream file) throws IOException
- Dump exceptions attribute to file stream in binary format.
- Parameters:
- file - Output file stream
- Overrides:
- dump in class Attribute
getConstantPool
public final ConstantPool getConstantPool()
- Returns:
- Constant pool used by this object.
- See Also:
- ConstantPool
getExceptionIndexTable
public final short[] getExceptionIndexTable()
- Returns:
- Array of indices into constant pool of thrown exceptions.
getNumberOfExceptions
public final short getNumberOfExceptions()
- Returns:
- Length of exception table.
setConstantPool
public final void setConstantPool(ConstantPool constant_pool)
- Parameters:
- constant_pool - Constant pool to be used for this object.
- See Also:
- ConstantPool
setExceptionIndexTable
public final void setExceptionIndexTable(short exception_index_table[])
- Parameters:
- exception_index_table.
- Also redefines number_of_exceptions according to table length.
toString
public final String toString()
- Returns:
- String representation, i.e. a list of thrown exceptions.
- Overrides:
- toString in class Object
