Class ScopeInstr

java.lang.Object

org.ek9lang.compiler.ir.instructions.IRInstr

org.ek9lang.compiler.ir.instructions.ScopeInstr

All Implemented Interfaces:

INode

public final class ScopeInstr
extends IRInstr

Specialized IR instruction for scope management (SCOPE_ENTER, SCOPE_EXIT, SCOPE_REGISTER).

Scope instructions provide exception-safe memory management for EK9, via ARC.

Method Summary

Modifier and Type	Method	Description
ScopeInstr	addOperand(String operand)	Add operand to this instruction.
ScopeInstr	addOperands(String... operands)	Add multiple operands to this instruction.
static ScopeInstr	enter(String scopeId, DebugInfo debugInfo)	Create scope enter instruction with debug info: SCOPE_ENTER scope_id.
static ScopeInstr	exit(String scopeId, DebugInfo debugInfo)	Create scope exit instruction with debug info: SCOPE_EXIT scope_id.
String	getObject()	Get object name for SCOPE_REGISTER instructions.
String	getScopeId()	Get scope ID for this scope instruction.
static ScopeInstr	register(String object, String scopeId, DebugInfo debugInfo)
static ScopeInstr	register(String object, BasicDetails basicDetails)	Create scope register instruction with debug info: SCOPE_REGISTER object, scope_id.
