Class TfitsDataNode

Method Details

• 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

• allowsChildren

  public boolean allowsChildren()

  Description copied from class: DefaultDataNode

  The DefaultDataNode implementation of this method returns false.

  Specified by:

  allowsChildren in interface DataNode

  Overrides:

  allowsChildren in class DefaultDataNode

  Returns:

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

• getChildIterator

  public Iterator getChildIterator()

  Description copied from class: DefaultDataNode

  The DefaultDataNode implementation of this method throws UnsupportedOperationException (DefaultDataNode.allowsChildren() is false).

  Specified by:

  getChildIterator in interface DataNode

  Overrides:

  getChildIterator in class DefaultDataNode

  Returns:

  an Iterator over the children. Each object iterated over should be a DataNode. Behaviour is undefined if this method is called on an object for which allowsChildren returns false.

• getPathSeparator

  Description copied from class: DefaultDataNode

  Returns a default separator string.

  Specified by:

  Returns:

  a short description of the type of this DataNode
