Doc from org.apache.bcel.generic.LoadClass.getType.

Returns the type associated with this instruction. LoadClass instances are always typed, but this type does not always refer to the type of the class or interface that it possibly forces to load. For example, GETFIELD would return the type of the field and not the type of the class where the field is defined. If no class is forced to be loaded, null is returned. An example for this is an NEWARRAY instruction that creates an int[][].

Parameters
cpg:ConstantPoolGen

A ConstantPoolGen

Returns:Type

return type of referenced field
