Description copied from interface: IOutputHandler

Retrieve a single output parameter definition by name

Specified by:

getOutputDef in interface IOutputHandler

Parameters:

name - name of the output parameter definition requested

Returns:

IOutputDef, output definition object

getFeedbackContentItem

public IContentItem getFeedbackContentItem()

Description copied from interface: IOutputHandler

Retrieve the ContentItem that describes the request interface for additional or missing information (missing from the original request)

Specified by:

getFeedbackContentItem in interface IOutputHandler

Returns:

ContentItem describing user feedback

getOutputContentItem

isResponseExpected

public boolean isResponseExpected()

Description copied from interface: IOutputHandler

Indicates whether or not the handler is expected to have data written to a response output stream managed by the handler. Typically, a handler will want to return true here if its getOutputContentItem or setOutput methods have been invoked and their invocations can result in a write to the response output stream that is managed by the handler. In general, handlers are responsible for setting this flag any time a client response is possible.

Specified by:

isResponseExpected in interface IOutputHandler

Returns:

true if the handler gave something the opportunity to write data to the its response output stream

setRuntimeContext
