-flag is ignored.- Specified by:
getMapping
in interfaceCellMapper
create
- whether a new view should created if a view does not already exist
-
createMapping
public CellView createMapping(java.lang.Object cell)
-
disconnect
public ConnectionSet disconnect(CellView[] cells)
Disconnects the edges incells
from the sources and targets that are not in this context and returns a ConnectionSet that defines the disconnection.
-
putMapping
public void putMapping(java.lang.Object cell, CellView view)
Associatescell
withview
in the graph context.- Specified by:
putMapping
in interfaceCellMapper
- Parameters:
cell
- the cell that constitutes the model elementview
- the view that constitutes the view element
