Method Detail

compare

public static int compare(byte[] b1,
                          int s1,
                          byte[] b2,
                          int s2,
                          Schema schema)

Compare binary encoded data. If equal, return zero. If greater-than, return 1, if less than return -1. Order is consistent with that of GenericData.compare(Object, Object, Schema).

compareBytes

public static int compareBytes(byte[] b1,
                               int s1,
                               int l1,
                               byte[] b2,
                               int s2,
                               int l2)

Lexicographically compare bytes. If equal, return zero. If greater-than, return a positive value, if less than return a negative value.

hashCode

public static int hashCode(byte[] bytes,
                           int start,
                           int length,
                           Schema schema)

Hash binary encoded data. Consistent with GenericData.hashCode(Object, Schema).

skipLong

public static int skipLong(byte[] bytes,
                           int start)

Skip a binary-encoded long, returning the position after it.
