Class IsFunctionDelegateSymbol

java.lang.Object

org.ek9lang.compiler.support.IsFunctionDelegateSymbol

All Implemented Interfaces:

Predicate<ISymbol>

public final class IsFunctionDelegateSymbol
extends Object
implements Predicate<ISymbol>

Predicate to determine if a symbol is a function delegate.

A function delegate is a variable whose type is a FunctionSymbol. This occurs when a function is stored in a variable, enabling:

• Dynamic function assignment: myFunc <- (x) is SomeFunction as function
• Function parameters: process(handler as SomeFunction)
• Function returns: getHandler() returns SomeFunction

When calling a function delegate, we must LOAD the variable rather than using FUNCTION_INSTANCE (which gets the singleton for named functions).
