Class Transmitter

java.lang.Object
  extended by net.sf.saxon.event.Transmitter
All Implemented Interfaces:
Source

public abstract class Transmitter
extends Object
implements Source

A Transmitter is a source of events sent to a Receiver. An implementation of this interface can be used in any Saxon interface allowing a Source to be supplied, and allows an input document to be created programmatically in the form of a stream of "push" events send to the supplied Receiver.

Transmitter

public Transmitter()
Method Detail

transmit

public abstract void transmit(Receiver receiver)
                       throws XPathException
Send events to a supplied Receiver

Parameters:
receiver - the Receiver to which events should be sent.

The pipelineConfiguration property of this Receiver is guaranteed to be initialized, providing access to objects such as the Saxon Configuration and NamePool.

The implementation of this class does not necessarily need to construct Receiver events directly. It can do so, for example, via the StreamWriterToReceiver class, which translates XMLStreamWriter events to Receiver events, or via the ReceivingContentHandler class, which translates SAX ContentHandler events to Receiver events.

Throws:
XPathException - if any failure occurs

setSystemId

public void setSystemId(String systemId)
Set the system identifier for this Source.

The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

Specified by:
setSystemId in interface Source
Parameters:
systemId - The system identifier as a URL string.

getSystemId

public String getSystemId()
Get the system identifier that was set with setSystemId.

Specified by:
getSystemId in interface Source
Returns:
The system identifier that was set with setSystemId, or null if setSystemId was not called.
