      public void configure(Map<String,byte[]> fileMetadata)
      Description copied from interface: AvroTypeManager
      Called when the type manager is reading out data from a data file such as in AvroFileReader
      Specified by:
      configure in interface AvroTypeManager
      Parameters:
      fileMetadata - metadata from the file header

      Throws:
      AvroTypeException

      public Optional<BiConsumer<BlockBuilder,Object>> overrideBuildingFunctionForSchema(org.apache.avro.Schema schema) throws AvroTypeException
      Description copied from interface: AvroTypeManager
      Object provided by FasterReader's deserialization with no conversions. Object class determined by Avro's standard generic data process BlockBuilder provided by Type returned above for the schema Possible to override for each primitive type as well.
      Specified by:
      overrideBuildingFunctionForSchema in interface AvroTypeManager
      Throws:
      AvroTypeException

      Description copied from interface: AvroTypeManager
      Extract and convert the object from the given block at the given position and return the Avro Generic Data forum. Type is either provided explicitly to the writer or derived from the schema using this interface.
      Specified by:
      overrideBlockToAvroObject in interface AvroTypeManager
      Throws:
      AvroTypeException

    • fromBigEndian

      public static long fromBigEndian(byte[] bytes)
      Decode a long from the two's complement big-endian representation.
      Parameters:
      bytes - the two's complement big-endian encoding of the number. It must contain at least 1 byte. It may contain more than 8 bytes if the leading bytes are not significant (either zeros or -1)
      Throws:
      ArithmeticException - if the bytes represent a number outside the range [-2^63, 2^63 - 1]

      Will resize big endian bytes to a desired array length while preserving the represented value.
      Throws:
      ArithmeticException - if conversion is not possible
