java.lang.Object org.apache.axis.handlers.BasicHandler org.apache.axis.SimpleChain
A Simple Chain is a 'composite' Handler in that it aggregates a collection of Handlers and also acts as a Handler which delegates its operations to the collection.
A Simple Chain initially has no Handlers. Handlers may be added until the chain is invoke()d after which Handlers may not be added (and any attempt to do so will throw an exception).

Method Summary | |
void |
addHandler(Handler handler)
Adds a handler to the end of the chain. |
boolean |
canHandleBlock(QName qname)
Indicate if this handler can process qname . |
void |
cleanup()
Cleanup is called when the chain containing this Handler object is done processing the chain. |
boolean |
contains(Handler handler)
Discover if a handler is in this chain. |
void |
generateWSDL(MessageContext msgContext)
Iterate over the chain letting each handler have a crack at contributing to a WSDL description. |
org.w3c.dom.Element |
getDeploymentData(org.w3c.dom.Document doc)
This will return the root element of an XML doc that describes the deployment information about this handler. |
Handler[] |
getHandlers()
Get the list of handlers in the chain. |
void |
init()
Init is called when the chain containing this Handler object is instantiated. |
void |
invoke(MessageContext msgContext)
Iterate over the chain invoking each handler. |
void |
onFault(MessageContext msgContext)
Notify the handlers in this chain because some handler later on has faulted - in reverse order. |
