Method Detail

addFromURL

public java.lang.Object addFromURL(Registry reg,
                                   java.net.URL url,
                                   ModifiableMap params,
                                   Workbench ui)

Reads an object from url. If necessary, an item reference to the object is created in the registry.

Parameters:

reg - registry in which the reference shall be created

url - URL to read

params - parameters, may be null

ui - workbench to use for UI

Returns:

the import object, or null in case of problems

createItemImpl

protected Item createItemImpl(Context ctx)

Overrides:

createItemImpl in class ObjectItemFactory

evaluate

public java.lang.Object evaluate(RegistryContext ctx,
                                 StringMap args)

Overrides:

evaluate in class ObjectItemFactory

getNTypeImpl

protected Node.NType getNTypeImpl()

Description copied from class: Node

This method returns the Node.NType which describes the managed fields of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:

getNTypeImpl in class ObjectItemFactory

Returns:

type describing the managed fields of the class of this node

newInstance

protected Node newInstance()

Description copied from class: Node

This method returns a new instance of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:

newInstance in class ObjectItemFactory

Returns:

new instance of class of this node
