Constructor Detail

GraphModelEvent

protected GraphModelEvent(IlpGraphModel source,
                          GraphModelEvent.Type type,
                          IlpRepresentationObject object)

Creates an event.

Parameters:

source - The model.

type - The event type (add/remove).

object - The object (that has been added/removed).

GraphModelEvent

protected GraphModelEvent(IlpGraphModel source,
                          GraphModelEvent.Type type,
                          Collection objects)

Creates an event.

Parameters:

source - The model.

type - The event type (roots added/removed).

objects - The roots (that have been added/removed).

Since:

JTGO 4.0

GraphModelEvent

protected GraphModelEvent(IlpGraphModel source,
                          GraphModelEvent.Type type,
                          IlpRepresentationObject object,
                          int[] indices,
                          IlpRepresentationObject[] children)

Creates an event.

Parameters:

source - The model.

type - The event type (children added/removed).

object - The parent object.

indices - The indices of the children (where the indices are taken after addition but before removal), in ascending order.

children - The children, in the same order as described in indices.

GraphModelEvent

protected GraphModelEvent(IlpGraphModel source,
                          GraphModelEvent.Type type,
                          IlpRepresentationObject link,
                          boolean origin,
                          IlpRepresentationObject oldEnd,
                          IlpRepresentationObject newEnd)

Creates an event.

Parameters:

source - The model.

type - The event type (link end changed).

link - The link.

origin - If this parameter is true, the from end is changed, otherwise the to end.

oldEnd - The previous link end object.

newEnd - The new link end object.
