public class LoadEntryInst
A class representing a three-address code load entry instruction (LoadEntryInst), which loads an entry from an indexable variable or string constant. A load entry instruction consists of a destination variable and a source operand (note: the operand must be indexable, e.g., an object variable), which are both inherited from LoadInst. A LoadEntryInst also consists of an index, which is either an int variable or constant. From TACInst it also inherits an opcode (LDENTRY).
