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.

AxisTableDeserializer
public AxisTableDeserializer(StoragePolicy storagePolicy)
- Constructor.
- Parameters:
storagePolicy
- policy for storing streamed table data
onStartChild
public org.apache.axis.message.SOAPHandler onStartChild(String namespace,
String localName,
String prefix,
Attributes atts,
org.apache.axis.encoding.DeserializationContext context)
throws SAXException
- Overrides:
onStartChild
in class org.apache.axis.encoding.DeserializerImpl
- Throws:
SAXException
onEndElement
public void onEndElement(String namespace,
String localName,
org.apache.axis.encoding.DeserializationContext context)
throws SAXException
- Overrides:
onEndElement
in class org.apache.axis.encoding.DeserializerImpl
- Throws:
SAXException
startTable
public void startTable(StarTable meta)
- Description copied from interface:
TableHandler
- Called when a table is about to be transmitted.
This call will occur somewhere between matched DATA element
startElement and endElement calls.
The metadata 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 to rowData is known, this value should be made
available as the row count of metadata
(
StarTable.getRowCount()
); if it is not known, the row count
should be -1. However, this object should not attempt to read
any of meta'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 interface TableHandler
- Parameters:
meta
- metadata object
rowData
public void rowData(Object[] row)
throws SAXException
- Description copied from interface:
TableHandler
- Called when a row has been read. This method will be called
between matched startTable and endTable calls.
- Specified by:
rowData
in interface TableHandler
- Parameters:
row
- array of data objects representing a row in the
current table
- Throws:
SAXException
endTable
public void endTable()
throws SAXException
- Description copied from interface:
TableHandler
- Called when there are no more rows to be transmitted.
- Specified by:
endTable
in interface TableHandler
- Throws:
SAXException
getValue
public Object getValue()
- Overrides:
getValue
in class org.apache.axis.encoding.DeserializerImpl
componentsReady
public boolean componentsReady()
- Overrides:
componentsReady
in class org.apache.axis.encoding.DeserializerImpl
valueComplete
public void valueComplete()
throws SAXException
- Overrides:
valueComplete
in class org.apache.axis.encoding.DeserializerImpl
- Throws:
