Interface ModelViewManager.Filter

Enclosing class:

ModelViewManager

public static interface ModelViewManager.Filter

Specifies the contract of graph element filters for views handled by ModelViewManager instances. Filters are always applied to elements of the model graph of a ModelViewManager to determine whether or not corresponding representatives should be inserted into or removed from an associated view graph.

Method Summary

boolean	acceptInsertion(Edge model) Returns true, iff a representative of the specified model edge should be inserted into an associated view graph; false otherwise.
boolean	acceptInsertion(Node model) Returns true, iff a representative of the specified model node should be inserted into an associated view graph; false otherwise.
boolean	acceptRemoval(Edge model) Returns true, iff a representative of the specified model edge should be removed from an associated view graph; false otherwise.
boolean	acceptRemoval(Node model) Returns true, iff a representative of the specified model node should be removed from an associated view graph; false otherwise.
boolean	acceptRetention(Edge model) Returns true, iff a representative of the specified model edge should be retained in an associated view graph; false otherwise.
boolean	acceptRetention(Node model) Returns true, iff a representative of the specified model node should be retained in an associated view graph; false otherwise.

Method Detail

acceptInsertion

boolean acceptInsertion(Node model)

Returns true, iff a representative of the specified model node should be inserted into an associated view graph; false otherwise.

Parameters:

model - a node in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model node should be inserted into an associated view graph; false otherwise.

acceptInsertion

boolean acceptInsertion(Edge model)

Returns true, iff a representative of the specified model edge should be inserted into an associated view graph; false otherwise.

Parameters:

model - an edge in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model edge should be inserted into an associated view graph; false otherwise.

acceptRemoval

boolean acceptRemoval(Node model)

Returns true, iff a representative of the specified model node should be removed from an associated view graph; false otherwise.

Parameters:

model - a node in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model node should be removed from an associated view graph; false otherwise.

acceptRemoval

boolean acceptRemoval(Edge model)

Returns true, iff a representative of the specified model edge should be removed from an associated view graph; false otherwise.

Parameters:

model - an edge in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model edge should be removed from an associated view graph; false otherwise.

acceptRetention

boolean acceptRetention(Node model)

Returns true, iff a representative of the specified model node should be retained in an associated view graph; false otherwise. This method is queried for model nodes that have an existing view representative when synchronizing a model graph to one or more of its view graphs or when synchronizing a view graph to its model graph.

Parameters:

model - a node in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model node should be retained in an associated view graph; false otherwise.

acceptRetention

boolean acceptRetention(Edge model)

Returns true, iff a representative of the specified model edge should be retained in an associated view graph; false otherwise. This method is queried for model edges that have an existing view representative when synchronizing a model graph to one or more of its view graphs or when synchronizing a view graph to its model graph.

Parameters:

model - an edge in the model graph of a ModelViewManager.

Returns:

true, iff a representative of the specified model edge should be retained in an associated view graph; false otherwise.
