Interface ConnectionOpenable.ConnectionOpenAutomaton<CON>

Type Parameters:

CON - The type of the connection to be used.

All Superinterfaces:

ConnectionOpenable<CON>, OpenedAccessor

All Known Subinterfaces:

ConnectionComponent.ConnectionAutomaton<CON>

All Known Implementing Classes:

ConnectionAutomatonImpl

Enclosing interface:

ConnectionOpenable<CON>

public static interface ConnectionOpenable.ConnectionOpenAutomaton<CON>
extends ConnectionOpenable<CON>, OpenedAccessor

The ConnectionOpenable.ConnectionOpenAutomaton 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 ConnectionOpenable.ConnectionOpenAutomaton interface has been introduced.

Method Detail

isOpenable

boolean isOpenable(CON aConnection)

Determines whether the given connection may get opened, if true then component may open a connection with the given connection via the ConnectionOpenable.open(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:

aConnection - The connection for which to determine whether it can be used to open a connection.

Returns:

True if ConnectionOpenable.open(Object) is theoretically possible.
