Method Detail

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

getNodeTLA in class DefaultDataNode

"..."

getNodeType

public String getNodeType()
Description copied from interface: DataNode

getNodeType in class DefaultDataNode
Returns:
a short description of the type of this DataNode

the name of the 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:

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

configureDetail

public void configureDetail(DetailViewer dv)
Description copied from class: DefaultDataNode
