Interface ByteArrayComparator

All Known Implementing Classes:

BasicByteArrayComparator, PureByteArrayComparator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ByteArrayComparator

An abstract super interface for comparing byte arrays.

Since:

0.8.0

Method Summary

Modifier and Type	Method and Description
int	compare(byte[] b1, int s1, int l1, byte[] b2, int s2, int l2) Compares the two byte array regions (as unsigned bytes), and returns their sign value.
default boolean	equals(byte[] b1, int s1, int l1, byte[] b2, int s2, int l2) Returns whether the each byte array region is equivalent or not.

Method Detail

equals

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

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

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

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

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

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
