Interface InputOutputOpenable.InputOutputOpenAutomaton<INPUT,OUTPUT>

Type Parameters:

INPUT - The type of the input connection to be used.

OUTPUT - The type of the output connection to be used.

All Superinterfaces:

InputOutputOpenable<INPUT,OUTPUT>, OpenedAccessor

All Known Subinterfaces:

InputOutputComponent.InputOutputAutomaton<INPUT,OUTPUT>

Enclosing interface:

InputOutputOpenable<INPUT,OUTPUT>

public static interface InputOutputOpenable.InputOutputOpenAutomaton<INPUT,OUTPUT>
extends InputOutputOpenable<INPUT,OUTPUT>, OpenedAccessor

The InputOutputOpenable.InputOutputOpenAutomaton interface defines those methods related to the opening of connection(s) life-cycle. The semantics of this interface is very similar to that of the Configurable.ConfigureAutomaton interface. To clarify the context regarding connections, the InputOutputOpenable.InputOutputOpenAutomaton interface has been introduced.

Method Detail

isOpenable

boolean isOpenable(INPUT aInputConnection,
                   OUTPUT aOutputConnection)

Determines whether the given connection may get opened, if true then component may open a connection with the given connection via the InputOutputOpenable.open(Object, Object) method. Usually no physical connection is established; usually criteria describing the provided connection are evaluated; for example the connection is tested against a black list, a white list or against well-formedness or whether the specified protocols are supported (in case of a connection being a String URL beginning with "http://", "ftp://" or similar). --------------------------------------------------------------------- CAUTION: Even in case true is returned, the actual opening of a connection may fail (e.g. due to network failure or authentication issues). ---------------------------------------------------------------------

Parameters:

aInputConnection - The input connection used for opening the connection.

aOutputConnection - The output connection used for opening the connection.

Returns:

True if InputOutputOpenable.open(Object, Object) is theoretically possible.
