question: public void findAndInit ( Object someObj ) { if ( someObj instanceof com . bbn . openmap . MapBean ) { Debug . message ( "overview" , "OverviewMapHandler found a MapBean object" ) ; setSourceMap ( ( MapBean ) someObj ) ; } }
target:  Called when the OverviewMapHandler is added to the BeanContext, and whenever an object is added to the BeanContext after that. The OverviewMapHandler looks for a MapBean to use as a source map, and for a PropertiesHandler object to use to load itself with layers and other properties. If a source MapBean is already set and another MapBean is found, the last MapBean will be used as the source MapBean. Every time a PropertyHandler is found, the OverviewMapHandler will reinitialize itself.
