Method Detail

defineSlot

public void defineSlot(java.lang.Object obj,
                       org.apache.bcel.generic.Type type)

Define local variable slot for object. The current code in the method must have the initial value for the variable on the stack

Parameters:

obj - owning object of slot

getSlot

public int getSlot(java.lang.Object obj)

Check if local variable slot defined for object.

Parameters:

obj - owning object of slot

Returns:

local variable slot assigned to object, or -1 if none

freeSlot

public void freeSlot(java.lang.Object obj)

Free local variable slot for object. This clears the usage of the slot (if one has been defined for the object) so it can be reused for other purposes.

Parameters:

obj - owning object of slot

handleExceptions

protected void handleExceptions()
                         throws JiBXException

Process accumulated exceptions. Just adds the checked exceptions that may be thrown within the body to the list for this method, passing them on to the caller for handling.

Specified by:

handleExceptions in class MethodBuilder

Throws:

JiBXException - on error in exception handling
