FunctionPointer

The FunctionPointer aspect can be attached to a C#, Swift or Java delegate type declaration in order to indicate that the type represents a C function pointer, not a block.

In Oxygene, this distinction is made based on the keyword used to declare the type – the block and (deprecated) delegate keywords declare a block, while the method and (also deprecated) function and procedure keywords declare a function pointer

type
  SomeFunction = public method(aString: String): Integer;

[FunctionPointer]
public delegate int SomeFunction(string aString);

@FunctionPointer public typealias SomeFunction = (String) -> (Int);

// delegates are not supported in Java (yet)

<FunctionPointer> Public Delegate Function SomeFunction(Parameter As String) As Int

Defined by the core compiler
