Method Details

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

createItemImpl

protected Object createItemImpl(Context ctx)

Overrides:

createItemImpl in class ObjectItemFactory

evaluate

public Object evaluate(RegistryContext ctx,
 StringMap args)

Overrides:

evaluate in class ObjectItemFactory

addFromURL

public Object addFromURL(Registry reg,
 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

addFromFilterSource

public Object addFromFilterSource(Registry reg,
 FilterSource fs,
 ModifiableMap params,
 Workbench ui)

Parameters:

reg - registry in which the reference shall be created

fs - a filtersource

params - parameters, may be null

ui - workbench to use for UI

Returns:

the import object, or null in case of problems

linkFromURLToResourceDir

public Object linkFromURLToResourceDir(Registry reg,
 URL url,
 ModifiableMap params,
 Workbench ui,
 Item dest)

Reads an object from url. Add an item from url into a resource directory. Does not create a copy on local file system.

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

dest - A resource directory in the registry where the file will be added
