Method Detail

onOpen

protected Sample.SampleType onOpen()
                            throws java.lang.Exception

Description copied from class: Cell

Called by Cell.open(). Performs the actual opening of communication session, while open checks only against access violation and handles exceptions. Must be overridden in subclasses if open is to be used. Overriders may assume that the cell is in Cell.State.CLOSED state.

Overrides:

onOpen in class Cell

Throws:

java.lang.Exception

onNext

protected Sample onNext()
                 throws java.lang.Exception

Description copied from class: Cell

Called by Cell.Stream.next(). Performs the actual generation of the next output sample, while Stream.next() checks only against access violation and handles exceptions. Must be overridden in the subclass if next is to be used, i.e. if the subclass should generate some output data. Overriders may assume that the cell is in Cell.State.OPEN state.

Overrides:

onNext in class Cell

Throws:

java.lang.Exception

onClose

protected void onClose()
                throws java.lang.Exception

Description copied from class: Cell

Called by Cell.Stream.close(). Performs the actual closing of communication session, while close checks only against access violation and handles exceptions. Must be overridden in subclasses if close is to be used. Usually the overrider will use onClose to release resources, to let them be garbage-collected. Overriders may assume that the cell is in Cell.State.OPEN state.

Overrides:

onClose in class Cell

Throws:

java.lang.Exception
