Constructor Summary

JGraphpadGraphModel()
Constructs a new empty graph model.

JGraphpadGraphModel(List roots, org.jgraph.graph.AttributeMap attributes, org.jgraph.graph.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.

Constructor Detail

JGraphpadGraphModel

public JGraphpadGraphModel()

Constructs a new empty graph model.

JGraphpadGraphModel

public JGraphpadGraphModel(List roots,
                           org.jgraph.graph.AttributeMap attributes,
                           org.jgraph.graph.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 Detail

cloneUserObject

protected Object cloneUserObject(Object userObject)

Extends the parent implementation to support cloning of JGraphpadBusinessObject.

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 JGraphpadBusinessObject. This implementation supports setting the value to String, JGraphpadRichTextValue or Map. If the new value is a map the complete properties of the user object are replaced with the specified map.

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 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.

Parameters:

attributes - The attributes to be processed.

Returns:

Returns the attributes used to undo the change.
