CASTransportable
public CASTransportable(CasPool casPool, OutOfTypeSystemData outOfTypeSystemData, UimaContext uimaContext, boolean includeDocText) This constructor is used on the service side - a CAS Pool reference is provided. We don't check a CAS out of the pool until we get a request.- Parameters:
casPool- the cas pooloutOfTypeSystemData- the out of type system datauimaContext- the uima contextincludeDocText- the include doc text

wrapAsSAXException
Create a SAXException that wraps the given IOException. The wrapping is done using the standard Java 1.4 mechanism, so that getCause() will work. Note that new SAXException(Exception) does NOT work.- Parameters:
e- an IOException to wrap- Returns:
- a SAX exception for which
getCause()will returne.
-
convertToIOException
Converts a Throwable to an IOException. Iftis an IOException, thentis returned. If not, then iftwas caused by an IOException (directly or indirectly), then that IOException is returned. Otherwise, a new IOException is created which wraps (is caused by)t.- Parameters:
t- the throwable to convert- Returns:
- an IOException which is either t, one of the causes of t, or a new IOException that wraps t.
