Examples of com.volantis.xml.pipeline.sax.ResourceOwner

com.volantis.xml.pipeline.sax.ResourceOwner
Implementation of this interface indicates that the object owns, or could own resources that need cleaning up.
Resources in this sense is a very asbstract term as it could refer to external resources such as sockets, or database connections but equally it could just refer to a Java object that can be reused and so needs adding back to an object pool.
