public interface OutputHandlerProvider
Event listener interface for QueryOutputHandlersEvent
s.
Implementing this interface allows to dynamically register OutputHandler
implementations
for a graphml document write action.
Implementations can be registered with
GraphMLHandler.addOutputHandlerProvider(OutputHandlerProvider)
or GraphMLWriter.addOutputHandlerProvider(y.io.graphml.output.OutputHandlerProvider)
or (preferably) with
the various DataProvider
based convenience methods on GraphMLHandler
that create the output
handler automatically.
