Module overrungl.glfw

Package overrungl.glfw

Interface IGLFWScrollFun

All Superinterfaces:

Callback

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IGLFWScrollFun
extends Callback

IGLFWScrollFun relies on preview features of the Java platform:

• IGLFWScrollFun refers to one or more preview APIs: FunctionDescriptor, MemorySegment.

Programs can only use IGLFWScrollFun when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

This is the function pointer type for scroll callbacks. A scroll callback function has the following signature:

@Invoker(IGLFWScrollFun::invoke)
void functionName(MemorySegment window, double xoffset, double yoffset);

Since:

0.1.0

descriptor

default FunctionDescriptorPREVIEW descriptor()

Description copied from interface: Callback

Returns the function descriptor of this callback.

Specified by:

descriptor in interface Callback

Returns:

the function descriptor of this callback

handle

default MethodHandle handle(MethodHandles.Lookup lookup)
                     throws NoSuchMethodException,
IllegalAccessException

Description copied from interface: Callback

Finds the method handle from the given method handles lookup.

Specified by:

handle in interface Callback

Parameters:

lookup - the lookup

Returns:

the method handle
