OXQDataSource, the Oracle implementation of XQDataSource.
This is the documentation for Oracle's standalone XQuery 1.0 processor. It is implemented purely in Java and runs in the same JVM as the application. This processor supports the XQuery API for Java (XQJ) as well as some non-standard extensions. Specifically, this package contains:
OXQDataSource, an implementation of XQDataSource, which is usually the starting point for XQJ users.javax.xml.xquery (for example, OXQStaticContext).entity resolver framework which allows users to control how external entities are obtained by the query processor. This includes but is not limited to modules, schemas, collections, collations, documents, XML entities, and external functions.resource closing framework which allows users to control how external resources are associated with XQJ objects and closed together with those XQJ objects.The Oracle implementation of XQJ is not thread-safe. For example, an instance of XQSequence must be accessed by only one thread. However, a restricted form of thread safety is supported for managing instances of XQConnection.
XQConnection serves as a factory for creating instances of XQExpression, XQPreparedExpression, XQItem, XQSequence, XQItemType, and XQSequenceType. One thread can manage the creation of these objects for use by other threads. For example, XQPreparedExpression instances created in one thread by the same connection can be used in other threads. Each XQPreparedExpression instance, however, must be executed by only one thread. Any user-defined implementations of OXQEntityResolver that are specified must be thread-safe when expressions from the same connection are evaluated concurrently.XQConnection.close() method closes all XQExpression and XQPreparedExpression instances that were obtained from the connection. Closing those instances closes all XQResultSequence and XQResultItem instances obtained from the expressions. The XQConnection.close() method can be called while expressions obtained from the connection are being processed in other threads. In this case, all registered resources held by the expressions (such as java.io.InputStream and java.io.Reader) are closed. This contract assumes that all registered resources support a thread-safe close method. For example, many JDK implementations of java.io.Closeable satisfy this requirement. But, many implementations of javax.xml.stream.XMLStreamReader do not provide a thread-safe close method. Implementations without this support can give unpredictable results if they are closed while a second thread is still reading. See OXQCloseable for more information.
