water.parser.parquet.TypeUtils

public class TypeUtils
extends java.lang.Object

Several helper methods inspired by Guava library - https://github.com/google/guava/. We want to avoid bringing guava dependency when possible. Duplicating some code from that library is a small sacrifice for not bringing the whole dependency

Method Summary

Modifier and Type	Method and Description
static int	intFromBytes(byte b1, byte b2, byte b3, byte b4) Returns the int value whose byte representation is the given 4 bytes, in big-endian order; equivalent to Ints.fromByteArray(new byte[] {b1, b2, b3, b4}).
static long	longFromBytes(byte b1, byte b2, byte b3, byte b4, byte b5, byte b6, byte b7, byte b8) Returns the long value whose byte representation is the given 8 bytes, in big-endian order; equivalent to Longs.fromByteArray(new byte[] {b1, b2, b3, b4, b5, b6, b7, b8}).

                                 byte b2,
                                 byte b3,
                                 byte b4,
                                 byte b5,
                                 byte b6,
                                 byte b7,
                                 byte b8)

Returns the long value whose byte representation is the given 8 bytes, in big-endian order; equivalent to Longs.fromByteArray(new byte[] {b1, b2, b3, b4, b5, b6, b7, b8}).
