Method Detail

copy

public Datastream copy()

Overrides:

copy in class Datastream

getContentStream

public InputStream getContentStream(Context context)
                             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

getContentLength

public long getContentLength(MIMETypedStream stream)

Returns the length of the content of this stream.

Parameters:

stream - the MIMETypedStream

Returns:

length the length of the content
