Class FunctionEncodedMemoryArea

java.lang.Object

com.pnfsoftware.jeb.core.units.code.asm.processor.memory.AbstractEncodedMemoryArea

com.pnfsoftware.jeb.core.units.code.asm.processor.memory.FunctionEncodedMemoryArea

All Implemented Interfaces:

IEncodedMemoryArea

public class FunctionEncodedMemoryArea
extends AbstractEncodedMemoryArea

Function Encoded Memory area uses a generic Function to determine the real memory area to use. Since Memory area is dynamic, the length is also dynamic and must be set by user (it is discouraged to use this FunctionEncodedMemoryArea in composed EncodedMemoryAreaList when length is dynamic).
