setSavedCollection

public static void setSavedCollection(Object uri,
 Object value,
 Environment env)

Add a uri-to-value binding that setSavedCollection can later return.

setSavedCollection

public static void setSavedCollection(Object uri,
 Object value)

Add a uri-to-value binding that setSavedCollection can later return.

getSavedCollection

public static Object getSavedCollection(Object uri,
 Environment env)

Default resolver for fn:collection. Return nodes previously bound using setSavedCollection.

getSavedCollection

public static Object getSavedCollection(Object uri)

Default resolver for fn:collection. Return nodes previously bound using setSavedCollection.

collection

public static Object collection(Object uri,
 Object base)
                         throws Throwable

Throws:

Throwable

docCached

public static Object docCached(Object uri,
 Object base)
                        throws Throwable

Parse an XML document, caching the result. Only positive results are cached; failures are not.) This implements the standard XQuery fn:doc function.

Throws:

Throwable

availableCached

public static boolean availableCached(Object uri,
 Object base)
                               throws Throwable

Check if an XML document is available, caching the result. Only positive results are cached; failures are not. Thus it is possible for a false result to be followed by a true result, but not vice versa. This implements the standard XQuery fn:doc-available function.

Throws:

Throwable
