Class CloseStatementGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.CloseStatementGenerator

All Implemented Interfaces:

Function<EK9Parser.CloseStatementContext, List<IRInstr>>

public final class CloseStatementGenerator
extends AbstractGenerator
implements Function<EK9Parser.CloseStatementContext, List<IRInstr>>

Generates IR for close statements.

Grammar support: closeStatement: CLOSE expression

The close statement is syntactic sugar for calling the _close() operator on an expression. This enables the pattern: close resource instead of resource.close().

The close operator is used for releasing external resources (sockets, database connections, file handles, etc.). It does NOT free the object's memory - that is handled by: - GC for JVM bytecode backend - ARC (RETAIN/RELEASE) for LLVM backend

Key behaviors: - Evaluates the expression to get the resource reference - Generates CALL resource._close() with void return - The close operator is pure, takes no arguments, and returns void
