Method Summary
protected  void	copy(Instruction orig)
boolean	equals(java.lang.Object other)           Two local variable instructions are equal if the local index they reference is equal and their types are equal, or if either index is 0/unset.
java.lang.Class	getType()           Get the type of variable to load; this is one of: int, float, double, long, or Object.class.
java.lang.String	getTypeName()           Get the type of variable to load; this is one of: int, float, double, long, or java.lang.Object.
TypedLocalVariableInstruction	setType(java.lang.Class type)           Set the type of variable to load; Object types other than Object.class will be demoted to Object.class, and primitives that have no direct support (byte, char, boolean) will be conerted to int.class.
TypedLocalVariableInstruction	setTypeName(java.lang.String name)           Set the type to load by name.
