Examples of DTMManagerDefault

com.sun.org.apache.xml.internal.dtm.ref.DTMManagerDefault
The default implementation for the DTMManager. %REVIEW% There is currently a reentrancy issue, since the finalizer for XRTreeFrag (which runs in the GC thread) wants to call DTMManager.release(), and may do so at the same time that the main transformation thread is accessing the manager. Our current solution is to make most of the manager's methods synchronized. Early tests suggest that doing so is not causing a significant performance hit in Xalan. However, it should be noted that there is a possible alternative solution: rewrite release() so it merely posts a request for release onto a threadsafe queue, and explicitly process that queue on an infrequent basis during main-thread activity (eg, when getDTM() is invoked). The downside of that solution would be a greater delay before the DTM's storage is actually released for reuse.
