The XmlStatistics
class encapsulates
statistical information about the number of keys in existence for a
given index. Statistics are available for the total number of keys
currently in use by the index, as well as the total number of unique
keys in use by the index. Use XmlStatistics::getNumberOfIndexedKeys
and XmlStatistics::getNumberOfUniqueKeys, respectively, to retrieve
these values.
Be aware that the number the number of keys maintained for an index is a function of the number and size of documents stored in the container, and of the type of index being examined.
XmlStatistics
objects are instantiated by
XmlContainer::lookupStatistics. This object is free threaded, and
can be safely shared among threads in an application.
