getStreamerName
Description copied from class:SystemFunction
Get a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.- Overrides:
getStreamerName
in classSystemFunction
- Returns:
- a name that identifies a class that supports streamed evaluation of this system
function, or null if no such class is available. The mapping of names to classes is
defined in the Saxon-EE class
StreamerMap
. In non-streaming Saxon editions (HE and PE) the method always returns null.
