Make a specific request to the underlying transport

Parameters:

endpoint - the endpoint to use when connecting to the resource

timeout - the maximum time the operation should block before returning. The call should return immediately if there is data available. If no data becomes available before the timeout elapses, null will be returned

Returns:

the result of the request wrapped in a UMOMessage object. Null will be returned if no data was avaialable

Throws:

Exception - if the call to the underlying protocal cuases an exception

Throws:

org.mule.umo.UMOException

getConnector

public org.mule.umo.provider.UMOConnector getConnector()

doDispose

protected void doDispose()
