                    throws javax.jms.JMSException

Throws:

Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Overrides:

close in class InputStream

Throws:

IOException

dispose

public void dispose()

getJMSProperties

public Map<String,Object> getJMSProperties()
                                    throws IOException

Return the JMS Properties which where used to send the InputStream

Returns:

jmsProperties

Throws:

IOException

receive

public ActiveMQMessage receive()
                        throws javax.jms.JMSException,
                               ActiveMQInputStream.ReadTimeoutException

This method allows the client to receive the Stream data as unaltered ActiveMQMessage object which is how the split stream data is sent. Each message will contains one chunk of the written bytes as well as a valid message group sequence id. The EOS message will have a message group sequence id of -1. This method is useful for testing, but should never be mixed with calls to the normal stream receive methods as it will break the normal stream processing flow and can lead to loss of data.

Returns:

an ActiveMQMessage object that either contains byte data or an end of strem marker.

Throws:

javax.jms.JMSException

ActiveMQInputStream.ReadTimeoutException

checkClosed

protected void checkClosed()
                    throws javax.jms.IllegalStateException

Throws:

javax.jms.IllegalStateException

public int read()
         throws IOException

Specified by:

Overrides:
