Examples of org.apache.xmlbeans.XmlCursor.dispose()

org.apache.xmlbeans.XmlCursor.dispose()
Deallocates resources needed to manage the cursor, rendering this cursor inoperable. Because cursors are managed by a mechanism which stores the XML, simply letting a cursor go out of scope and having the garbage collector attempt to reclaim it may not produce desirable performance.

So, explicitly disposing a cursor allows the underlying implementation to release its responsibility of maintaining its position.

After a cursor has been disposed, it may not be used again. It can throw IllegalStateException or NullPointerException if used after disposal.

                String namespace = temp.getName().getNamespaceURI();
                temp.dispose();
                if(!namespace.equals(GENERIC_NAMESPACE) && !namespace.equals(this.namespace) && !namespace.equals(OLD_GENERIC_NAMESPACE)) {
                    throw new DeploymentException("Cannot handle web plan with namespace "+namespace+" -- expecting "+GENERIC_NAMESPACE+" or "+this.namespace);
