Method Detail
setSystemId
void setSystemId(String systemId)
Set the system identifier for this Source.
The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

-
systemId
- The system identifier as a URL string.

object is empty. Empty means that there is no input available from this Source.

- The default implementation of this method throws
UnsupportedOperationException
. - Returns:
- true if the
Source
object is empty, false otherwise
