Method Detail

getExceptions

public Class[] getExceptions()

Specified by:

getExceptions in interface ExceptionThrower

getLoadClassType

public ObjectType getLoadClassType(ConstantPoolGen cpg)

Description copied from interface: LoadClass

Returns the ObjectType of the referenced class or interface that may be loaded and resolved.

Specified by:

getLoadClassType in interface LoadClass

Returns:

object type that may be loaded or null if a primitive is referenced

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object
