Method Details
-
getName
Description copied from interface:DataNode
Gets the name of this object. This is an intrinsic property of the object.- Specified by:
getName
in interfaceDataNode
- Overrides:
getName
in classDefaultDataNode
- Returns:
- the name of the object
-
getPathElement
Description copied from class:DefaultDataNode
The DefaultDataNode implementation returns the label as a default path element.- Specified by:
getPathElement
in interfaceDataNode
- Overrides:
getPathElement
in classDefaultDataNode
- Returns:
- the node's label
-
getPathSeparator
Description copied from class:DefaultDataNode
Returns a default separator string.- Specified by:
getPathSeparator
in interfaceDataNode
- Overrides:
getPathSeparator
in classDefaultDataNode
- Returns:
- "."
-
getNodeTLA
Description copied from class:DefaultDataNode
The DefaultDataNode implementation returns the string "...".- Specified by:
getNodeTLA
in interfaceDataNode
- Overrides:
getNodeTLA
in classDefaultDataNode
- Returns:
- "..."
-
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 interfaceDataNode
- Overrides:
getNodeType
in classDefaultDataNode
- 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 interfaceDataNode
- Overrides:
allowsChildren
in classDefaultDataNode
- Returns:
true
if the node is of a type which can have child nodes,false
otherwise
-
getChildIterator
Description copied from class:DefaultDataNode
The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren()
is false).- Specified by:
getChildIterator
in interfaceDataNode
- Overrides:
getChildIterator
in classDefaultDataNode
- Returns:
- an
Iterator
over the children. Each object iterated over should be aDataNode
. Behaviour is undefined if this method is called on an object for whichallowsChildren
returnsfalse
.
-
configureDetail
Description copied from class:DefaultDataNode
No custom configuration is performed.- Specified by:
configureDetail
in interfaceDataNode
- Overrides:
configureDetail
in classDefaultDataNode
- Parameters:
dv
- the detail viewer which this node is given an opportunity to configure
-
