Method Detail

concat

public static byte[] concat(byte[] array1,
                            byte[] array2)

Concatenate the given byte arrays into one, with overlapping array elements included twice.

The order of elements in the original arrays is preserved.

Parameters:

array1 - the first array.

array2 - the second array.

Returns:

the new array.

concatAll

public static byte[] concatAll(byte[]... arrays)

Concatenate the given byte arrays into one, with overlapping array elements included twice. Returns a new, empty array if arrays was empty and returns the first array if arrays contains only a single array.

The order of elements in the original arrays is preserved.

Parameters:

arrays - the arrays.

Returns:

the new array.

split

public static byte[][] split(byte[] source,
                             int c)

Split source into partitioned arrays using delimiter c.

Parameters:

source - the source array.

c - delimiter.

Returns:

the partitioned arrays.

mergeArrays

public static byte[][] mergeArrays(byte[] firstArray,
                                   byte[]... additionalArrays)

Merge multiple byte arrays into one array

Parameters:

firstArray - must not be null

additionalArrays - must not be null

Returns:

getBytes

public static byte[] getBytes(ByteBuffer byteBuffer)

Extract a byte array from ByteBuffer without consuming it.

Parameters:

byteBuffer - must not be null.

Returns:
