Class ScopeInstr

java.lang.Object

org.ek9lang.compiler.ir.IRInstr

org.ek9lang.compiler.ir.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)	Create scope enter instruction: SCOPE_ENTER scope_id.
static ScopeInstr	enter(String scopeId, DebugInfo debugInfo)	Create scope enter instruction with debug info: SCOPE_ENTER scope_id.
static ScopeInstr	exit(String scopeId)	Create scope exit instruction: SCOPE_EXIT 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)	Create scope register instruction: SCOPE_REGISTER object, scope_id Register object for automatic cleanup when scope exits.
static ScopeInstr	register(String object, String scopeId, DebugInfo debugInfo)	Create scope register instruction with debug info: SCOPE_REGISTER object, scope_id.

Method Details

enter

public static ScopeInstr enter(String scopeId)

Create scope enter instruction: SCOPE_ENTER scope_id. Establishes a new memory management scope for exception safety.

enter

public static ScopeInstr enter(String scopeId,
 DebugInfo debugInfo)

Create scope enter instruction with debug info: SCOPE_ENTER scope_id.

exit

public static ScopeInstr exit(String scopeId)

Create scope exit instruction: SCOPE_EXIT scope_id. Automatically RELEASE all objects registered in this scope.

exit

public static ScopeInstr exit(String scopeId,
 DebugInfo debugInfo)

Create scope exit instruction with debug info: SCOPE_EXIT scope_id.

register

public static ScopeInstr register(String object,
 String scopeId)

Create scope register instruction: SCOPE_REGISTER object, scope_id Register object for automatic cleanup when scope exits.

register

public static ScopeInstr register(String object,
 String scopeId,
 DebugInfo debugInfo)

Create scope register instruction with debug info: SCOPE_REGISTER object, scope_id.

addOperand
