Method Detail

getName

public String getName()

Description copied from interface: DataNode

Gets the name of this object. This is an intrinsic property of the object.

Specified by:

getName in interface DataNode

Overrides:

getName in class DefaultDataNode

Returns:

the name of the object

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

public String getNodeTLA()

Description copied from class: DefaultDataNode

The DefaultDataNode implementation returns the string "...".

Specified by:

getNodeTLA in interface DataNode

Overrides:

getNodeTLA in class DefaultDataNode

Returns:

"..."

getNodeType

public 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 interface DataNode

Overrides:

getNodeType in class DefaultDataNode

Returns:

a short description of the type of this DataNode

hasDataObject

public boolean hasDataObject(DataType dtype)

Description copied from class: DefaultDataNode

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).

Specified by:

hasDataObject in interface DataNode

Overrides:

hasDataObject in class DefaultDataNode

Parameters:

dtype - data object type of interest

Returns:

true iff a subsequent call of getDataObject(type) is likely to be successful

getDataObject

public Object getDataObject(DataType dtype)
                     throws DataObjectException

Description copied from class: DefaultDataNode

The DefaultDataNode implementation returns any data object which has been registered using DefaultDataNode.registerDataObject(uk.ac.starlink.datanode.nodes.DataType, java.lang.Object).

Specified by:

getDataObject in interface DataNode

Overrides:

getDataObject in class DefaultDataNode

Parameters:

dtype - data object type of interest

Returns:

data object of type type

Throws:

DataObjectException

makeStarTable

public static StarTable makeStarTable(String loc)
                               throws NoSuchDataException

Throws:

NoSuchDataException

makeStarTable

public static StarTable makeStarTable(DataSource datsrc)
                               throws NoSuchDataException

Throws:

NoSuchDataException

getTableFactory
