Class VOTableDOMBuilder
java.lang.Object
uk.ac.starlink.votable.VOTableDOMBuilder
- All Implemented Interfaces:
- ContentHandler
public class VOTableDOMBuilder
- extends Object
- implements ContentHandler
Custom DOM builder for parsing VOTable documents or fragments.
For the most part it builds a DOM, but within data-heavy elements
(those which represent table data) it intercepts SAX events
directly to construct the table data
which it stores in the corresponding TableElement node,
rather than installing bulk data
as CDATA or Element nodes within the resulting DOM.

VOTableDOMBuilder
public VOTableDOMBuilder(StoragePolicy storagePolicy,
boolean strict)
- Constructor.
- Parameters:
storagePolicy
- policy for bulk data storagestrict
- true iff you want strict enforcement of VOTable standard
getDocument
public VODocument getDocument()
- Returns the DOM document built by this parser, following a parse.
Each TableElement has a TabularData object attached from which
the actual table data can be retrieved.
- Returns:
- VOTable DOM
