Class DefaultReconnectionFeature

    • Method Detail

      • canReconnect

        public boolean canReconnect​(IReconnectionContext context)
        Called by the framework to check if this feature can perform the currently triggered reconnection request. The default implementation checks if
        • A connection and a new target anchor are passed in the given IReconnectionContext
        • The connection passed in the context has a start and end anchor
        • The new anchor is not located directly in the diagram
        Can be overridden by clients to add additional checks.
        Specified by:
        canReconnect in interface IReconnection
        Parameters:
        context - the context object holding all the reconnection information
        Returns:
        true if the feature is able to deal with the reconnection request, false otherwise or if the tool needs to prohibit the reconnection for the given situation.
      • getNewAnchor

        protected Anchor getNewAnchor​(IReconnectionContext context)
        Can be overridden by the user to influence the target anchor to use for the reconnect.
        Parameters:
        context - the context holding the reconnection information
        Returns:
        the new anchor to use as target for the reconnect
      • reconnect

        public final void reconnect​(IReconnectionContext context)
        Called by the framework to perform the currently triggered reconnection request. The default implementation calls the preReconnect(IReconnectionContext) and postReconnect(IReconnectionContext) hooks. The reconnect is done by either replacing the start anchor (in case it matches the old anchor passed in the context) or the end anchor with the new anchor.
        Specified by:
        reconnect in interface IReconnection
        Parameters:
        context - the context object holding all the reconnection information
      • canExecute

        public boolean canExecute​(IContext context)
        Called by the framework to check if this feature can perform the currently triggered reconnection request. Delegates to the canReconnect(IReconnectionContext) method in case the passed context is a IReconnectionContext.
        Specified by:
        canExecute in interface IFeature
        Parameters:
        context - the context object holding all the reconnection information
        Returns:
        true if the feature is able to deal with the reconnection request, false otherwise or if the tool needs to prohibit the reconnection for the given situation.

      • execute

        public void execute​(IContext context)
        Called by the framework to execute this feature to perform the currently triggered reconnection request. Delegates to the reconnect(IReconnectionContext) method in case the passed context is a IReconnectionContext.
        Specified by:
        execute in interface IFeature
        Parameters:
        context - the context object holding all the reconnection information
        See Also:
        IContext
      • getName

        public java.lang.String getName()
        Returns the display name of the feature to use e.g. within a context menu.
        Specified by:
        getName in interface IName
        Overrides:
        getName in class AbstractFeature
        Returns:
        the display name of the feature
      • canceledReconnect

        public void canceledReconnect​(IReconnectionContext context)
        Called by the framework in case a started reconnection operation has been cancelled, e.g. by pressing ESC, selecting another tool from the palette etc.
        Specified by:
        canceledReconnect in interface IReconnection
        Parameters:
        context - the context object holding all the reconnection information

        0.9
      • canStartReconnect

        public boolean canStartReconnect​(IReconnectionContext context)
        Called by the framework after the connection has been selected. Determines whether connection endpoint can be dragged to start reconnection.
        Specified by:
        canStartReconnect in interface IReconnection
        Parameters:
        context - the context object holding information about the connection and old anchor
        Returns:
        true
