Method Detail

getContentStream

public java.io.InputStream getContentStream()
                                     throws StreamIOException

Gets an InputStream to the content of this externally-referenced datastream.

The DSLocation of this datastream must be non-null before invoking this method.

If successful, the DSMIME type is automatically set based on the web server's response header. If the web server doesn't send a valid Content-type: header, as a last resort, the content-type is guessed by using a map of common extensions to mime-types.

If the content-length header is present in the response, DSSize will be set accordingly.

Overrides:

getContentStream in class Datastream

Throws:

StreamIOException
