  Constructor

Parameters:
  `workHandler` - the Handler we're going to wrap with Fault semantics.

Method Detail

### init

    public void init()

  Description copied from class: `BasicHandler`
  Stubbed-out methods. Override in your child class to implement any real behavior.

  Specified by:
    `init` in interface `Handler`
  Overrides:
    `init` in class `BasicHandler`

### cleanup

    public void cleanup()

  Description copied from interface: `Handler`
  Cleanup is called when the chain containing this Handler object is done processing the chain.

  Specified by:
    `cleanup` in interface `Handler`
  Overrides:
    `cleanup` in class `BasicHandler`

### invoke

    public void invoke(MessageContext msgContext)
                throws AxisFault

  Invokes the specified handler. If there's a fault the appropriate key will be calculated and used to find the fault chain to be invoked. This assumes that the workHandler has caught the exception and already done its fault processing - as needed.

  Specified by:
    `invoke` in interface `Handler`
  Specified by:
    `invoke` in class `BasicHandler`
    `AxisFault`

### onFault

    public void onFault(MessageContext msgContext)

  Some handler later on has faulted so we need to process the fault.

  Specified by:
    `onFault` in interface `Handler`
  Overrides:
    `onFault` in class `BasicHandler`

### canHandleBlock

    public boolean canHandleBlock(QName qname)

  Description copied from interface: `Handler`
  Can this Handler process this QName?

  Specified by:
    `canHandleBlock` in interface `Handler`
  Overrides:
    `canHandleBlock` in class `BasicHandler`
