question: private Map < String , VPlexDeviceInfo > mapDevices ( VPlexDeviceInfo parentDevice ) { _logger . info ( "\tmapping device " + parentDevice . getName ( ) ) ; Map < String , VPlexDeviceInfo > mirrorDevices = new TreeMap < String , VPlexDeviceInfo > ( ) ; for ( VPlexDeviceInfo dev : parentDevice . getChildDeviceInfo ( ) ) { mirrorDevices . put ( dev . getSlotNumber ( ) , dev ) ; } return mirrorDevices ; }
target:  Creates a Map of slot numbers to VPlexDeviceInfo child objects of a given top level device VPlexDeviceInfo, for use in creating the VPLEX native mirror map.
