Method Detail

get

public Exception_info get(int offset)

Description copied from interface: IExceptionHandlerTable

Returns Exception_info descriptor at a given offset.

Specified by:

get in interface IExceptionHandlerTable

Parameters:

offset - exception offset [must be in [0, size()) range; input not checked]

Returns:

Exception_info descriptor [never null]

size

public int size()

Description copied from interface: IExceptionHandlerTable

Returns the number of descriptors in this collection [can be 0].

Specified by:

size in interface IExceptionHandlerTable

length

public long length()

Description copied from interface: IExceptionHandlerTable

Returns the total length of this table when converted to .class format [including 2 count bytes]

Specified by:

length in interface IExceptionHandlerTable

clone

public java.lang.Object clone()

Performs a deep copy.

Specified by:

clone in interface IExceptionHandlerTable

Overrides:

clone in class java.lang.Object

writeInClassFormat

public void writeInClassFormat(UDataOutputStream out)
                        throws java.io.IOException

Specified by:

writeInClassFormat in interface IClassFormatOutput

Throws:

java.io.IOException

add

public int add(Exception_info exception)

Description copied from interface: IExceptionHandlerTable

Adds a new Exception_info descriptor to this collection. No duplicate checks are made. It is the responsibility of the caller to ensure that all data referenced in 'exception' will eventually be consistent with method's bytecode and the class's constant pool.

Specified by:

add in interface IExceptionHandlerTable

Parameters:

exception - new exception descriptor [may not be null]

set

public Exception_info set(int offset,
                          Exception_info exception)

Description copied from interface: IExceptionHandlerTable

Replaces the Exception_info descriptor at a given offset. No duplicate checks are made. No exception type compatibility checks are made. It is the responsibility of the caller to ensure that all data referenced in 'exception' will eventually be consistent with method's bytecode and the class's constant pool.

Specified by:

set in interface IExceptionHandlerTable

Parameters:

offset - exception offset [must be in [0, size()) range; input not checked]

exception - new exception descriptor [may not be null]

Returns:

previous exception descriptor at this offset [never null]
