DllExport

The DllExport aspect marks a static method, static field or a type to be available externally from the current project (usually a dynamic library, such a .dll, .so, or .dylib, depending on platform).

It takes an optional String parameter which lets you override the default name the symbol will be exported under.

For all platforms, exports a method, static field or type from the given dynamic library. This can also be set globally by setting the option. When used on methods or fields, the SymbolName attribute can be used to override the name which it gets exported with.

Note that DllExport is not required to use type from one Elements library project from a different Elements on the same platform. All public types and their pubbic or protected members will be available when referencing an Elements project via its .fx file. It is also not required to expose Cocoa classes to Objective-C-based Xcode projects using your library.

DllExport is meant for exporting symbols for use by other development tools, (such as C/C++), or to be called back by operating system APIs.

JNI Export and Anrdroid Extensions

When exporting methods for use with Java Native Interface (JNI), for example to export methods from an Android NDK project, the JNIExport can be used instead of DllExpore. JNIExport will automatically apply the proper name mangling required for JNI, and more.

Island Only

The DllExport aspect is available only on the Island platform.

type
  MyClass = public class 
  public  
    [DllExport("DifferentName")]
    class method MyMethod();
    begin
      ...
    end;
  end;

public class MyClass
{
    [DllExport("DifferentName")]
    public static void MyMethod()
    {
        ...
    }
}

public class MyClass {
    @DllExport("DifferentName")
    public func MyMethod() {
