cvs commit: xml-xalan/java/src/org/apache/xml/dtm/ref TestDTM.java
jkesselm 02/03/19 12:44:27
Modified: java/src/org/apache/xml/dtm/ref TestDTM.java
Log:
Replace old version, which was specific to particular implentations of
DTM, with one which is specific only to DTMManagerDefault and which
can be generalized more easily to conduct other tests.

/**
- * Tests the DTM by creating
+ * Unit test for DTMManager/DTM
*
- * REWRITTEN to use SAX2 ContentHandler APIs -- original draft used
- * an incomplete/incorrect version of SAX1 DocumentHandler, which is
- * being phased out as quickly as we can possibly manage it.
+ * Loads an XML document from a file (or, if no filename is supplied,
+ * an internal string), then dumps its contents. Replaces the old
+ * version, which was specific to the ultra-compressed implementation.
+ * (Which, by the way, we probably ought to revisit as part of our ongoing
+ * speed/size performance evaluation.)
*
- * %TBD% I _think_ the SAX convention is that "no namespace" is expressed
- * as "" rather than as null (which is the DOM's convention). What should
- * DTM expect? What should it do with the other?
- */
+ * %REVIEW% Extend to test DOM2DTM, incremental, DOM view of the DTM,
+ * whitespace-filtered, indexed/nonindexed, ...
+ * */
