Constructor Detail

• OptimizingModbusBlockFetcher

  OptimizingModbusBlockFetcher(SchemaDevice schemaDevice, ModbusDevice modbusDevice)

Method Detail

• getAllowedGapReadSize

   final Integer getAllowedGapReadSize()

  How many registers may needlessly be read to optimize fetching

• setAllowedGapReadSize

   final Unit setAllowedGapReadSize(Integer allowedGapReadSize)

• calculateModbusQueries

   List<ModbusQuery> calculateModbusQueries(List<Field> fields, Long maxAge)

  Reduce the full set of modbus queries to a lower number by combining requests that are close enough together.

  Parameters:

  fields - The list of fields that must be updated

  maxAge - The maximum age (in milliseconds) of the data for it to need an update.

• splitMergedModbusRequest

   final List<ModbusQuery> splitMergedModbusRequest(MergedModbusQuery modbusQuery, Function1<MergedModbusQuery, Boolean> isFull)

  Split an existing MergedModbusQuery into 2 or more smaller modbus queries. This simply walks over the underlying modbus queries and recombines them up to a limit which is determined by the 'isFull' lambda.

• mergeQueries

   final List<ModbusQuery> mergeQueries(List<ModbusQuery> providedModbusQueries, Integer maxRegistersPerModbusRequest, Integer maxDiscretesPerModbusRequest)

  Combine the provided set of queries into a smaller set of Merged Queries where possible.
