Field Details

VALUE_EMPTY

public static final Object VALUE_EMPTY

Defines the EMPTY_VALUE constant to be used in nested maps in order to remove properties from business objects.

Constructor Details

RichTextGraphModel

public RichTextGraphModel()

Constructs a new empty graph model.

RichTextGraphModel

public RichTextGraphModel(List roots,
 AttributeMap attributes,
 ConnectionSet cs)

Constructs a new graph model using the specified root cells and attributes (for the model) and establishes the connections defined in the specified connection set between the cells.

Parameters:

roots - The roots to be inserted into the model.

attributes - The model's attributes.

cs - The connections to be established.

Method Details

acceptsSource

public boolean acceptsSource(Object edge,
 Object port)

Description copied from class: DefaultGraphModel

Returns true if port is a valid source for edge. edge and port must be objects previously obtained from this data source.

Specified by:

acceptsSource in interface GraphModel

Overrides:

acceptsSource in class DefaultGraphModel

Returns:

true if port is a valid source for edge.

acceptsTarget

public boolean acceptsTarget(Object edge,
 Object port)

Description copied from class: DefaultGraphModel

Returns true if port is a valid target for edge. edge and port must be objects previously obtained from this data source.

Specified by:

acceptsTarget in interface GraphModel

Overrides:

acceptsTarget in class DefaultGraphModel

Returns:

true if port is a valid target for edge.

cloneUserObject

protected Object cloneUserObject(Object userObject)

Extends the parent implementation to support cloning of

invalid reference

JGraphpadBusinessObject

.

Overrides:

cloneUserObject in class DefaultGraphModel

Parameters:

userObject - The user object to be cloned.

Returns:

Returns the cloned user object.

valueForCellChanged

public Object valueForCellChanged(Object cell,
 Object newValue)

Extends the parent implementation to support changing the value on

invalid reference

JGraphpadBusinessObject

. This implementation supports setting the value to String,

invalid reference

JGraphpadRichTextValue

or Map. If the new value is a map the complete properties of the user object are replaced with the specified map.

Specified by:

valueForCellChanged in interface GraphModel

Overrides:

valueForCellChanged in class DefaultGraphModel

Parameters:

cell - The cell to change the value for.

newValue - The new value to use for the cell.

Returns:

Returns the old value of the cell.

handleAttributes

protected Map handleAttributes(Map attributes)

Extends the parent implementation to support changing properties on

invalid reference

JGraphpadBusinessObject

by adding a map for the business object to the nested map which is passed to an insert or edit call. The special VALUE_EMPTY is used to remove a property from a business object.

Overrides:

handleAttributes in class DefaultGraphModel

Parameters:

attributes - The attributes to be processed.

Returns:

Returns the attributes used to undo the change.
