Class SplittedSaxJoiner

java.lang.Object
  sk.uniba.euromath.gene.controller.SplittedSaxJoiner

final class SplittedSaxJoiner
extends Object

Resolves emp:mark elements and caches results. Able to process SAX results only; all other results are converted to SAX in the following manner:

• DOM is simply converted to SAX
• Stream is fully read and converted to a single text event.
• Object is converted to a single text event using its toString() function.

Results are cached in case when multiple emp:marks with same id occurs.

exactly one startDocument() occurs on start and endDocument() occurs on end. Start / end document events produced by Sources produced by the resolver are suppressed.
