public java.lang.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
Following copied from interface: org.apache.bcel.generic.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.
Overrides:
