compare

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

Compare two objects in binary. b1[s1:l1] is the first object, and b2[s2:l2] is the second object.

パラメータ:

b1 - The first byte array.

s1 - The position index in b1. The object under comparison's starting index.

l1 - The length of the object in b1.

b2 - The second byte array.

s2 - The position index in b2. The object under comparison's starting index.

l2 - The length of the object under comparison in b2.

戻り値:

An integer result of the comparison.
