Method Detail

getNodeTLA

public String getNodeTLA()

Description copied from class: DefaultDataNode

The DefaultDataNode implementation returns the string "...".

Specified by:

getNodeTLA in interface DataNode

Overrides:

getNodeTLA in class DocumentDataNode

Returns:

"..."

getNodeType

public String getNodeType()

Description copied from interface: DataNode

Returns a short sentence indicating what kind of node this is. The return value should be just a few words. As a rough guideline it should indicate what the implementing class is.

Specified by:

getNodeType in interface DataNode

Overrides:

getNodeType in class DocumentDataNode

Returns:

a short description of the type of this DataNode

allowsChildren

public boolean allowsChildren()

Description copied from class: DefaultDataNode

The DefaultDataNode implementation of this method returns false.

Specified by:

allowsChildren in interface DataNode

Overrides:

allowsChildren in class DocumentDataNode

Returns:

true if the node is of a type which can have child nodes, false otherwise

getPathSeparator

public String getPathSeparator()

Description copied from class: DefaultDataNode

Returns a default separator string.

Specified by:

getPathSeparator in interface DataNode

Overrides:

getPathSeparator in class DocumentDataNode

Returns:

"."

getChildIterator

public Iterator getChildIterator()

Description copied from class: DefaultDataNode

The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).

Specified by:

getChildIterator in interface DataNode

Overrides:

getChildIterator in class DocumentDataNode

Returns:

an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.

No custom configuration is performed.

Specified by:

configureDetail in interface DataNode

Overrides:

configureDetail in class DocumentDataNode

Parameters:

dv - the detail viewer which this node is given an opportunity to configure
