question: public boolean validateSensor ( String sensorName , LayoutBlock blk , Component openFrame ) { if ( sensorName . length ( ) < 1 ) { return false ; } Sensor s = blk . validateSensor ( sensorName , openFrame ) ; if ( s == null ) { return false ; } return true ; }
target:  Validates that the supplied occupancy sensor name corresponds to an existing sensor and is unique among all blocks. If valid, returns true and sets the block sensor name in the block. Else returns false, and does nothing to the block.
