public class TableHDUDataNode extends HDUDataNode
DataNode
interface for
representing binary or ASCII tables in FITS HDUs.Constructor and Description |
---|
TableHDUDataNode(Header header,
FITSDataNode.ArrayDataMaker hdudata)
Initialises a
TableHDUDataNode from an Header
object. |
Modifier and Type | Method and Description |
---|---|
boolean |
allowsChildren()
The DefaultDataNode implementation of this method returns
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.
|
StarTable |
getStarTable()
Returns the StarTable containing the data.
|
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) . |
