Class OptNode

java.lang.Object
org.apache.sysds.runtime.controlprogram.parfor.opt.OptNode
public class OptNode extends Object
Internal representation of a plan alternative for program blocks and instructions in order to enable efficient and simple recursive enumeration and plan changes. This is only used within the optimizer and therefore not visible to any other component.
