XMLDataNode

public XMLDataNode(Source xsrc)
            throws NoSuchDataException
Throws:
NoSuchDataException
Method Detail

getName

public String getName()
Description copied from interface: DataNode
Gets the name of this object. This is an intrinsic property of the object.

Specified by:
getName in interface DataNode
Overrides:
getName in class DefaultDataNode
Returns:
the name of the object

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 DefaultDataNode
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 DefaultDataNode
Returns:
a short description of the type of this DataNode

getPathElement

public String getPathElement()
Description copied from class: DefaultDataNode
The DefaultDataNode implementation returns the label as a default path element.

Specified by:
getPathElement in interface DataNode
Overrides:
getPathElement in class DefaultDataNode
Returns:
the node's label

getPathSeparator

public String getPathSeparator()
Description copied from class: DefaultDataNode
Returns a default separator string.

Specified by:
getPathSeparator in interface DataNode
Overrides:
getPathSeparator in class DefaultDataNode
Returns:
"."

getDescription

public String getDescription()
Description copied from interface: DataNode
Gets a concise description of this object. The form of the description will depend on the type of node, but it might detail the shape or type of data represented, or otherwise give some information additional to the name. It should not include the return value of the getName method, since they may be presented together. It should be on one line, and preferably no longer than around 70 characters. The null value may be returned if there is nothing to say.

Specified by:
getDescription in interface DataNode
Overrides:
getDescription in class DefaultDataNode
Returns:
a short string describing this object

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

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 DefaultDataNode
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.

configureDetail

public void configureDetail(DetailViewer dv)
Description copied from class: DefaultDataNode
No custom configuration is performed.

Specified by:
configureDetail in interface DataNode
Overrides:
configureDetail in class DefaultDataNode
Parameters:
dv - the detail viewer which this node is given an opportunity to configure
