Class AspectProxyInstr

java.lang.Object

org.ek9lang.compiler.ir.instructions.IRInstr

org.ek9lang.compiler.ir.instructions.AspectProxyInstr

All Implemented Interfaces:

INode

public final class AspectProxyInstr
extends IRInstr

High-level IR instruction for creating an aspect-woven proxy.

This instruction tells the backend to generate a synthetic proxy class that wraps a delegate component with ordered aspect instances. The proxy extends the base type and, for each public non-operator method, generates a wrapped version with before/after advice chains.

All instance construction (delegate, aspects, their dependencies) happens via normal CALL/RETAIN/SCOPE_REGISTER instructions before this instruction. This instruction takes the pre-constructed instances and returns a wired proxy.

The backend is responsible for:

• Generating a proxy class extending baseType
• Creating fields for delegate and aspect instances
• For each public non-operator method: JoinPoint creation, before-chain, delegate call (with try/finally), after-chain (reverse order)
• Proxy naming via source token hash

Method Summary

Modifier and Type	Method	Description
static AspectProxyInstr	createAspectProxy(AspectProxyDetails details)	Create an aspect proxy instruction from details.
boolean	forwardsClose()	True when the proxy forwards _close() to its delegate (the base type has a close operator).
List<String>	getAspectTemps()
List<String>	getAspectTypeFqns()
String	getBaseTypeFqn()
String	getDelegateTemp()
String	getDelegateTypeFqn()
List<AspectProxyDetails.ProxyMethodInfo>	getProxyMethods()
IToken	getSourceToken()
boolean	implementsCloseable()	True when the proxy must implement the Closeable trait (only its delegate has a close).
String	toString()
