Package org.jruby.ir.instructions

Class ResultBaseInstr

java.lang.Object

org.jruby.ir.instructions.Instr

org.jruby.ir.instructions.ResultBaseInstr

All Implemented Interfaces:

ResultInstr

Direct Known Subclasses:

NoOperandResultBaseInstr, NOperandResultBaseInstr, OneOperandResultBaseInstr, TwoOperandResultBaseInstr

public abstract class ResultBaseInstr
extends Instr
implements ResultInstr

For most instrs that have a result this is their base class. Some instrs, most notably callinstr is more complicated because we would rather use inheritance to share call-related logic.
