Class EndianUtils

java.lang.Object
dev.vortex.api.proto.EndianUtils
public final class EndianUtils extends Object
Utility class for handling endianness conversions in Vortex protocol buffers. Provides methods for converting between big-endian and little-endian byte representations, particularly for decimal values that need to be serialized to the Vortex format.

    • reverse

      public static byte[] reverse(com.google.protobuf.ByteString src)
      Reverses the byte order of a ByteString, converting from one endianness to another.
      Parameters:
      src - the source ByteString to reverse
      Returns:
      a new byte array with bytes in reverse order

    • littleEndianDecimal

      public static byte[] littleEndianDecimal(BigDecimal decimal)
      Converts a BigDecimal to a little-endian byte array representation suitable for Vortex decimals. The method extracts the unscaled value of the decimal, converts it from big-endian to little-endian, and pads to a standard size (1, 2, 4, 8, 16, or 32 bytes) with proper sign extension for negative values.
      Parameters:
      decimal - the BigDecimal value to convert
      Returns:
      a little-endian byte array representation of the decimal's unscaled value
      Throws:
      RuntimeException - if the BigDecimal is too large for Arrow
