Method Detail

equals

public boolean equals(byte[] b1,
                      int s1,
                      int l1,
                      byte[] b2,
                      int s2,
                      int l2)

Description copied from interface: ByteArrayComparator

Returns whether the each byte array region is equivalent or not.

Specified by:

equals in interface ByteArrayComparator

Parameters:

b1 - the first byte array

s1 - the starting offset in the first byte array (in bytes)

l1 - the length in the first byte array (in bytes)

b2 - the second byte array

s2 - the starting offset in the second byte array (in bytes)

l2 - the length in the second byte array (in bytes)

Returns:

true if the each byte array range is equivalent, otherwise false

compare

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

Description copied from interface: ByteArrayComparator

Compares the two byte array regions (as unsigned bytes), and returns their sign value.

Specified by:

compare in interface ByteArrayComparator

Parameters:

b1 - the first byte array

s1 - the starting offset in the first byte array (in bytes)

l1 - the length in the first byte array (in bytes)

b2 - the second byte array

s2 - the starting offset in the second byte array (in bytes)

l2 - the length in the second byte array (in bytes)

Returns:

< 0, = 0, or > 0 as the first byte array range is less than, equal to, or greater than the second range
