Element Details

value

String value

The output branch fed by this parameter. Used by OutputEmitter parameters, which always feed exactly one branch, and by MultiOutputIterator parameters streaming to a single branch.

Returns:

the branch name, __default__ if not set.

Default:

"__default__"

branches

String[] branches

The branches a MultiOutputIterator parameter routes records to, when it feeds more than one. This is declarative metadata only: it lets the design/Studio layer know the output connections of the component, the routing itself is done at runtime through TaggedOutput or MultiOutputIterator.setIterator(String, java.util.Iterator). When left empty, value() is used, which covers the single branch streaming case. It is not supported on OutputEmitter parameters.

Returns:

the branch names, empty to fallback on value().

Default:

{}
