Examples of org.apache.openjpa.kernel.Extent.list()

org.apache.openjpa.kernel.Extent.list()
Returns a list of all objects represented by this extent. This method creates a {@link List} by traversing the entire iterator returned by acall to {@link #iterator}. This means that {@link Collection#size} willwork correctly, but if the extent represents a large data set, this method may be quite slow and may consume quite a bit of memory.
