Class StoreEntryInst

java.lang.Object
  cfg.TACInst
      cfg.StoreEntryInst

public class StoreEntryInst
extends TACInst

A class representing a three-address code store entry instruction (StoreEntryInst), which stores a value an entry from an indexable variable or string constant. A store entry instruction consists of a destination operand (which must be indexable, e.g., an object variable), a source operand, and an index (which must be either an int variable or constant). From TACInst it also inherits an opcode (STENTRY).
