Method Detail
-
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
-
configureDetail
public void configureDetail(DetailViewer dv)
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
-
getDescription
public java.lang.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 thegetName
method, since they may be presented together. It should be on one line, and preferably no longer than around 70 characters. Thenull
value may be returned if there is nothing to say.- Specified by:
getDescription
in interfaceDataNode
- Overrides:
getDescription
in classDefaultDataNode
- Returns:
- a short string describing this object
-
getNodeTLA

getNodeTLA
in classDefaultDataNode
- Returns:
- "..."
-
getNodeType
public java.lang.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 interfaceDataNode
- Overrides:
getNodeType
in classDefaultDataNode
- Returns:
- a short description of the type of this
DataNode
-
getPathSeparator
public java.lang.String getPathSeparator()

getPathSeparator
in classDefaultDataNode
- Returns:
- "."
-
getPathElement
public java.lang.String 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
-
getStarTable
public uk.ac.starlink.table.StarTable getStarTable()
-
isStarTable
public boolean isStarTable()
-
hasDataObject
public boolean hasDataObject(DataType dtype)
