public final class ConnectQosSaxFactory
extends XmlQoSBase
implements I_ConnectQosFactory

This class encapsulates the qos of a login() or connect().

So you don't need to type the 'ugly' XML ASCII string by yourself. After construction access the ASCII-XML string with the toXml() method.
A typical connect QoS could look like this:

<qos>
   <securityService type="htpasswd" version="1.0">
     <![CDATA[
     <user>joe</user>
     <passwd>secret</passwd>
     ]]>
   </securityService>

   <session name='/node/heron/client/joe' timeout='3600000'
                 maxSessions='10' clearSessions='false'
                 reconnectSameClientOnly='false'/>

   <ptp>true</ptp>  

   <duplicateUpdates>true</duplicateUpdates>

   <!-- The client side queue (is ignored on server side): -->
   <queue relating='client' type='CACHE' version='1.0' maxEntries='1000' maxBytes='4000' onOverflow='exception'>
      <address type='IOR'>
         IOR:10000010033200000099000010....
      </address>
   <queue>

   <!-- Configures the server side callback queue: -->
   <queue relating='callback' type='CACHE' version='1.0' maxEntries='1000' maxBytes='4000' onOverflow='deadMessage'>
      <callback type='IOR' sessionId='4e56890ghdFzj0'>
         IOR:10000010033200000099000010....
         <burstMode collectTime='400' />
      </callback>
   </queue>
</qos>
 

NOTE: As a user of the Java client helper classes (client.I_XmlBlasterAccess) you don't need to create the

<callback>

element. This is generated automatically from I_XmlBlasterAccess when instantiating the callback driver.

A typical connect return QoS could look like this (this is the acknowledge returned by the server to the client on successful connect):

<qos>
   <securityService type="htpasswd" version="1.0">
     <![CDATA[
     <user>joe</user>
     <passwd>secret</passwd>
     ]]>
   </securityService>

   <session name='/node/heron/client/joe/-9' timeout='3600000' maxSessions='10' clearSessions='false'
               clearSessions='false' sessionId='sessionId:192.168.1.4-null-1042823803521-2074317763-3'/>

   <reconnected>false</reconnected>  <!-- Has the client reconnected to an existing session? -->

   <!-- The server side callback queue: -->
   <queue relating='callback' type='CACHE' version='1.0' maxEntries='1000' maxBytes='4000' onOverflow='deadMessage'>
      <callback type='XMLRPC' bootstrapHostname='192.168.1.4' sessionId='4e56890ghdFzj0'>
         http://192.168.1.4:8081/
         <burstMode collectTime='400' />
      </callback>
   <queue>
</qos>

Method Detail

readObject

public ConnectQosData readObject(java.lang.String xmlQos)
                          throws XmlBlasterException

Parses the given xml Qos and returns a ConnectQosData holding the data. Parsing of connect() and connect-return QoS is supported here. This call is thread safe if not intermixed with getConnectQosData() calls.

Specified by:

readObject in interface I_ConnectQosFactory

Parameters:

the - XML based ASCII string

Throws:

XmlBlasterException

getConnectQosData

public ConnectQosData getConnectQosData()

This is NOT thread safe so you need a new factory for each parse. Use this variant if you have a bigger xml markup and want to delegate startElement(), endElement() calls to this. PRECONDITION: Call setConnectQosData() first!

setConnectQosData

public void setConnectQosData(ConnectQosData data)

If a delegate call startElement() directly

startElement

public void startElement(java.lang.String uri,
                         java.lang.String localName,
                         java.lang.String name,
                         org.xml.sax.Attributes attrs)

Start element, event from SAX parser.

Specified by:

startElement in interface org.xml.sax.ContentHandler

Overrides:

startElement

public void startElement(java.lang.String uri,

                         java.lang.StringBuffer character,
                         org.xml.sax.Attributes attrs)

Start element from SAX parsing, call as delegate delivers the character

endElement

public void endElement(java.lang.String uri,
                       java.lang.String localName,
                       java.lang.String name)
