Instance Method Details

#instantiate(str, gcSuspendCount = 0) ⇒ Object

Parses str and calls start_tag, end_tag, set_attribute and text methods of a subclass.

If gcSuspendCount is specified, the garbage collector will be disabled for that number of start or end tags. After that period it will clean up and then be disabled again. A value of about 1000 can significantly improve overall performance. The memory usage normally does not increase. Depending on the work done for every xml tag the value might have to be adjusted.
