Type Parameters:

H - The type of the handle.

Method Summary

Modifier and Type	Method	Description
void	close(H aHandle)	Closes or pre-closes (flush) the component identified by the given handle.
default void	closeUnchecked(H aHandle)	Closes the component by calling close(Object) without you to require catching an CloseException.
boolean	hasClosable(H aHandle)	Determines whether the handle reference is closable by implementing the Closable interface.

Method Detail

hasClosable

boolean hasClosable(H aHandle)
             throws UnknownHandleRuntimeException

Determines whether the handle reference is closable by implementing the Closable interface.

Parameters:

aHandle - The handle to test whether the reference provides the according functionality.

Returns:

True in case the reference provides the according functionality.

Throws:

UnknownHandleRuntimeException - in case the handle is unknown.

close

void close(H aHandle)
    throws CloseException,
           UnknownHandleRuntimeException,
           UnsupportedHandleOperationRuntimeException,
           IllegalHandleStateChangeRuntimeException

Closes or pre-closes (flush) the component identified by the given handle. Throws a CloseException as upon close we may have to do things like flushing buffers which can fail (and would otherwise fail unhandled or even worse unnoticed).

Parameters:

aHandle - The handle identifying the component.

Throws:

CloseException - Thrown in case closing or pre-closing (flushing) fails.

UnknownHandleRuntimeException - in case the given handle is unknown.

UnsupportedHandleOperationRuntimeException - in case the reference of the handle does not support the requested operation.

IllegalHandleStateChangeRuntimeException - Thrown in case a state change is not possible due to the current state the referenced component is in.

closeUnchecked

default void closeUnchecked(H aHandle)

Closes the component by calling close(Object) without you to require catching an CloseException.

Parameters:

aHandle - The handle identifying the component.

Throws:

org.refcodes.exception.HiddenException - encapsulates the cause and is thrown upon encountering a CloseException exception
