question: private boolean removeOutputNode_internal ( String outputNodeId ) { if ( ! outputNodes . containsKey ( outputNodeId ) ) { log . warning ( "node " + outputNodeId + " is not an output node for " + nodeId ) ; } BNode outputNode = outputNodes . remove ( outputNodeId ) ; return ( outputNode != null ) ; }
target:  Removes an outgoing relation to the node. This method should never be called outside the removeRelation method, to ensure consistency between the input and output links.
