Constructor Detail

ExceptionMethodBuilder

public ExceptionMethodBuilder(String name,
                              org.apache.bcel.generic.Type ret,
                              org.apache.bcel.generic.Type[] args,
                              ClassFile cf,
                              int access)

Constructor with types specified.

Parameters:

name - method name to be built

ret - method return type

args - types of arguments

cf - owning class file information

access - flags for method access

ExceptionMethodBuilder

public ExceptionMethodBuilder(String name,
                              String sig,
                              ClassFile cf,
                              int access)

Constructor from signature.

Parameters:

name - method name to be built

sig - method signature

cf - owning class file information

access - flags for method access

ExceptionMethodBuilder

public ExceptionMethodBuilder(String name,
                              String sig,
                              ClassFile cf)

Constructor from signature for public, final method.

Parameters:

name - method name to be built

sig - method signature

cf - owning class file information

Method Detail

defineSlot

public int defineSlot(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

type - variable type

Returns:

slot number

getSlot

public int getSlot(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(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()

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:
