toHex

@NonNull
public static String toHex(byte b)

Retrieves a hexadecimal representation of the provided byte.

参数:

b - The byte to encode as hexadecimal.

返回:

A string containing the hexadecimal representation of the provided byte.

toHex

public static void toHex(byte b,
                         @NonNull
                         StringBuilder buffer)

Appends a hexadecimal representation of the provided byte to the given buffer.

参数:

b - The byte to encode as hexadecimal.

buffer - The buffer to which the hexadecimal representation is to be appended.

toHex

public static void toHex(byte b,
                         @NonNull
                         ByteStringBuffer buffer)

Appends a hexadecimal representation of the provided byte to the given buffer.

参数:

b - The byte to encode as hexadecimal.

buffer - The buffer to which the hexadecimal representation is to be appended.

toHex

@NonNull
public static String toHex(@NonNull
                                     byte[] b)

Retrieves a hexadecimal representation of the contents of the provided byte array. No delimiter character will be inserted between the hexadecimal digits for each byte.

参数:

b - The byte array to be represented as a hexadecimal string. It must not be null.

返回:

A string containing a hexadecimal representation of the contents of the provided byte array.

toHex

public static void toHex(@NonNull
                         byte[] b,
                         @NonNull
                         StringBuilder buffer)

Retrieves a hexadecimal representation of the contents of the provided byte array. No delimiter character will be inserted between the hexadecimal digits for each byte.

参数:

b - The byte array to be represented as a hexadecimal string. It must not be null.

buffer - A buffer to which the hexadecimal representation of the contents of the provided byte array should be appended.

toHex

public static void toHex(@NonNull
                         byte[] b,
                         @Nullable
                         String delimiter,
                         @NonNull
                         StringBuilder buffer)

Retrieves a hexadecimal representation of the contents of the provided byte array. No delimiter character will be inserted between the hexadecimal digits for each byte.

参数:

b - The byte array to be represented as a hexadecimal string. It must not be null.

delimiter - A delimiter to be inserted between bytes. It may be null if no delimiter should be used.

buffer - A buffer to which the hexadecimal representation of the contents of the provided byte array should be appended.

toHexPlusASCII

@NonNull
public static String toHexPlusASCII(@NonNull
                                              byte[] array,
                                              int indent)

Retrieves a hex-encoded representation of the contents of the provided array, along with an ASCII representation of its contents next to it. The output will be split across multiple lines, with up to sixteen bytes per line. For each of those sixteen bytes, the two-digit hex representation will be appended followed by a space. Then, the ASCII representation of those sixteen bytes will follow that, with a space used in place of any byte that does not have an ASCII representation.

参数:

array - The array whose contents should be processed.

indent - The number of spaces to insert on each line prior to the first hex byte.

返回:

A hex-encoded representation of the contents of the provided array, along with an ASCII representation of its contents next to it.

                                  StringBuilder buffer)

Appends a hex-encoded representation of the contents of the provided array to the given buffer, along with an ASCII representation of its contents next to it. The output will be split across multiple lines, with up to sixteen bytes per line. For each of those sixteen bytes, the two-digit hex representation will be appended followed by a space.
