Examples of InstructionHandle

com.sun.org.apache.bcel.internal.generic.InstructionHandle

Instances of this class give users a handle to the instructions contained in an InstructionList. Instruction objects may be used more than once within a list, this is useful because it saves memory and may be much faster. Within an InstructionList an InstructionHandle object is wrapped around all instructions, i.e., it implements a cell in a doubly-linked list. From the outside only the next and the previous instruction (handle) are accessible. One can traverse the list via an Enumeration returned by InstructionList.elements(). @version $Id: InstructionHandle.java,v 1.1.2.1 2005/07/31 23:45:01 jeffsuttor Exp $ @author M.
