public class AxisTableDeserializer
extends org.apache.axis.encoding.DeserializerImpl
implements TableHandler
Custom deserializer for VOTables.
The serialized stream is assumed to be a valid VOTABLE element containing
a RESOURCE element containing a TABLE element.
The implementation of this class is tailored to various ill-documented idiosyncracies of AXIS's deserialization machinery. Tinker at your peril.

startTable
public void startTable(uk.ac.starlink.table.StarTable meta) Description copied from interface:TableHandler
Called when a table is about to be transmitted. This call will occur somewhere between matched DATA elementstartElement
andendElement
calls. Themetadata
argument signals column and table metadata argument about the table whose rows are about to be transmitted. If the number of rows that will be transmitted via subsequent calls torowData
is known, this value should be made available as the row count ofmetadata
(StarTable.getRowCount()
); if it is not known, the row count should be -1. However, this object should not attempt to read any ofmeta
's cell data.The data to be transmitted in subsequent calls of
acceptRow
must match the metadata transmitted in this call in the same way that rows of a StarTable must match its own metadata (number and content clases of columns etc).- Specified by:
startTable
in interfaceTableHandler
- Parameters:
meta
- metadata object
-
rowData
Description copied from interface:TableHandler
Called when a row has been read. This method will be called between matchedstartTable
andendTable
calls.- Specified by:
rowData
in interfaceTableHandler
- Parameters:
row
- array of data objects representing a row in the current table- Throws:
SAXException
-
endTable
Description copied from interface:TableHandler
Called when there are no more rows to be transmitted.- Specified by:

in interfaceTableHandler
- Throws:
