public class ImageHDUDataNode extends HDUDataNode
DataNode
interface for
representing Header and Data Units (HDUs) in FITS files.Constructor and Description |
---|
ImageHDUDataNode(Header hdr,
FITSDataNode.ArrayDataMaker hdudata)
Initialises an
ImageHDUDataNode from a Header
object. |
Modifier and Type | Method and Description |
---|---|
boolean |
allowsChildren()
The DefaultDataNode implementation of this method returns
false.
|
void |
configureDetail(DetailViewer dv)
No custom configuration is performed.
|
Iterator |
getChildIterator()
The DefaultDataNode implementation of this method throws
UnsupportedOperationException
(
DefaultDataNode.allowsChildren() is false). |
Object |
getDataObject(DataType dtype)
The DefaultDataNode implementation returns any data object
which has been registered using
DefaultDataNode.registerDataObject(uk.ac.starlink.datanode.nodes.DataType, java.lang.Object) . |
String |
getDescription()
Gets a concise description of this object.
|
String |
getNodeTLA()
The DefaultDataNode implementation returns the string "...".
|
String |
getNodeType()
Returns a short sentence indicating what kind of node this is.
|
boolean |
hasDataObject(DataType dtype)
The DefaultDataNode implementation returns true for
only those data objects which have been registered using
DefaultDataNode.registerDataObject(uk.ac.starlink.datanode.nodes.DataType, java.lang.Object) . |
