nl_tokens: Helper to handle the result of getNext and call the user s callback as appropriate . The callback will see one of the following patterns : - callback ( [ an Error object ] undefined ) -- an error ocurred . - callback ( null [ a Packet object ] ) -- data from under the tree . - callback ( null null ) -- end of tree .
pl_tokens: function result ( error , varbinds ) { if ( combinedTimeoutExpired ) { return ; } if ( error ) { clearTimeout ( combinedTimeoutTimer ) ; callback ( error ) ; } else { if ( inTree ( options . startOid , varbinds [ 0 ] . oid ) ) { if ( varbinds [ 0 ] . value === 'endOfMibView' || varbinds [ 0 ] . value === 'noSuchObject' || varbinds [ 0 ] . value === 'noSuchInstance' ) { clearTimeout ( combinedTimeoutTimer ) ; callback ( null , vbs ) ; } else if ( vbs . length && compareOids ( vbs . slice ( - 1 ) [ 0 ] . oid , varbinds [ 0 ] . oid ) !== 1 ) { return callback ( new Error ( 'OID not increasing' ) ) ; } else { vbs . push ( varbinds [ 0 ] ) ; var next = { oid : varbinds [ 0 ] . oid } ; defaults ( next , options ) ; self . getNext ( next , <mask> ) ; } } else { clearTimeout ( combinedTimeoutTimer ) ; callback ( null , vbs ) ; } } }
