Method Detail

create

M create(java.lang.Class aNodeClass,
         CreationContext aContext)
                                      throws CannotInstantiateModifiableNodeException

Creates a modifiable layout node. The created node can be inserted into the model controller using an appropriate insert method defined on a subinterface of this interface. The node will not appear in the model unless it is inserted.

Specified by:

create in interface ModelController<T extends LayoutNode,M extends ModifiableLayoutNode>

Parameters:

aNodeClass - interface class of node to insert

aContext - a context specifying information about the node to create, may be null. If the node class is LayoutControl, then a non-null LayoutControlCreationContext needs to be specified.

Returns:

a modifiable node; never null

Throws:

CannotInstantiateModifiableNodeException - in case the modifiable node cannot be instantiated

Parameters:

node - node to set the deletable flag for. The flag is set for the last layer of the node
