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

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

Cocoa and Island Only

The FunctionPointer aspect is available on the Cocoa and Island platforms only.
