Method Detail

toLong

public static long toLong(byte[] bytes)

Converts a byte array to a long value. Reverses toBytes(long)

toLong

public static long toLong(byte[] bytes,
                          int offset)

Converts a byte array to a long value. Assumes there will be SIZEOF_LONG bytes available.

toBytes

public static byte[] toBytes(long val)

Convert a long value to a byte array using big-endian.

toBytes

public static byte[] toBytes(String str)

Converts a string to a UTF-8 byte array.

toCachedBytes

public static byte[] toCachedBytes(String str)

Converts a string to a UTF-8 byte array. This method will cache results and return cached results, so the resulting byte arrays must not be modified.

tail

public static byte[] tail(byte[] arr,
                          int length)

head

public static byte[] head(byte[] arr,
                          int length)

toString

public static String toString(byte[] arr)

toString

public static String toString(byte[] arr,
                              int off,
                              int len)

encodeHexString

public static String encodeHexString(@Nullable
                                     byte[] name)

decodeHexString

public static byte[] decodeHexString(@Nullable
                                     String hexString)

addIfNotEmpty

public static void addIfNotEmpty(com.google.common.base.MoreObjects.ToStringHelper helper,
                                 String name,
                                 byte[] bytes)

encodeBase64String

public static String encodeBase64String(byte[] data)

encodeBase64String

public static String encodeBase64String(byte[] data,
                                        int offset,
                                        int length)

decodeBase64

public static byte[] decodeBase64(String data)

startsWith

public static boolean startsWith(byte[] bytes,
                                 byte[] prefix)

Return true if the byte array on the right is a prefix of the byte array on the left.

compareTo

public static int compareTo(byte[] left,
                            byte[] right)

Compare two byte arrays.

Returns:

0 if equal, < 0 if left is less than right, etc
