Class StackMap

java.lang.Object

com.ibm.j9ddr.vm29.j9.stackmap.StackMap

public class StackMap
extends Object

The StackMap determines the shape of the operand stack at a particular point in the code. This is used by the stackwalker to figure out which stack slots hold objects and which hold primitive data for each frame. LocalMap does a similar job for the local/automatic stack variables.
