Method Details

invoke

@QtDeclaredFinal
@QtUninvokable
public final void invoke(Object... arguments)
                  throws QUnsuccessfulInvocationException

Overloaded function for invoke(void.class, arguments).

Parameters:

arguments -

Throws:

QUnsuccessfulInvocationException

invoke

@QtDeclaredFinal
@QtUninvokable
public final <R> R invoke(Class<R> returnType,
 Object... arguments)
                   throws QUnsuccessfulInvocationException

Overloaded function for invoke(QGenericReturnType.of(returnType), arguments).

Parameters:

returnType -

arguments -

Throws:

QUnsuccessfulInvocationException

invoke

@QtUninvokable
public final <R> R invoke(QGenericReturnType<R> returnType,
 Object... arguments)
                   throws QUnsuccessfulInvocationException

Invokes the underlying function pointer with given arguments.

Object types are used as pointers, value types as call-by-value. This also applies for the return value.

Use QGenericArgument to specify call-by-reference. E.g. QGenericArgument.value("any string").asConstRef() for const QString&

Requires Java Native Access library (JNA) in class path.

Parameters:

returnType -

arguments - argument values or wrapped as QGenericArgument

Throws:

QUnsuccessfulInvocationException

cast

@QtUninvokable
public final <T extends QtObjectInterface> T cast(Class<T> functionalInterface)

Converts this function pointer into given functional interface type.

Parameters:

functionalInterface -

Returns:

converted function pointer

cast

@QtUninvokable
public static <T extends QtObjectInterface> T cast(QtObjectInterface function,
 Class<T> functionalInterface)

Converts the given function into given functional interface type.

Parameters:

functionalInterface -

Returns:

converted function pointer

invoke

public void invoke()
