Module overrungl.glfw

Package overrungl.glfw

Interface IGLFWErrorFun

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 IGLFWErrorFun
extends Callback

IGLFWErrorFun relies on preview features of the Java platform:

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

Programs can only use IGLFWErrorFun 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 error callbacks. An error callback function has the following signature:

@Invoker(IGLFWErrorFun::invoke)
void callbackName(int errorCode, String description);

Pointer lifetime

The error description string is valid until the callback function returns.

Since:

0.1.0

Method Details

invoke

void invoke(int errorCode,
 String description)

The function pointer type for error callbacks.

Parameters:

errorCode - An error code. Future releases may add more error codes.

description - A UTF-8 encoded string describing the error.

ninvoke

default void ninvoke(int errorCode,
 MemorySegmentPREVIEW description)

set

default MemorySegmentPREVIEW set()

Sets the error callback.

Returns:

The previous callback or NULL.

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

Throws:

NoSuchMethodException - if the method does not exist

IllegalAccessException - if access checking fails, or if the method is static, or if the method's variable arity modifier bit is set and asVarargsCollector fails
