Class CastInstrAsmGenerator

java.lang.Object

org.ek9lang.compiler.backend.jvm.AbstractAsmGenerator

org.ek9lang.compiler.backend.jvm.CastInstrAsmGenerator

All Implemented Interfaces:

Consumer<CastInstr>

final class CastInstrAsmGenerator
extends AbstractAsmGenerator
implements Consumer<CastInstr>

Specialized ASM generator for CastInstr processing.

Generates JVM CHECKCAST instruction for explicit type casting. Used in Scenario 2 wrappers where delegate method returns Any but wrapper method returns a more specific type.
