org.xnio.ByteString

All Implemented Interfaces:

Serializable, Comparable<ByteString>

public final class ByteString
extends Object
implements Comparable<ByteString>, Serializable

An immutable string of bytes. Since instances of this class are guaranteed to be immutable, they are safe to use as Option values and in an OptionMap.

Method Detail

of

public static ByteString of(byte... bytes)

Create a byte string of the given literal bytes. The given array is copied.

Parameters:

bytes - the bytes

Returns:

the byte string

copyOf

public static ByteString copyOf(byte[] b,
                int offs,
                int len)

Create a byte string from the given array segment.

Parameters:

b - the byte array

offs - the offset into the array

len - the number of bytes to copy

Returns:

the new byte string

getBytes

public static ByteString getBytes(String str,
                  String charset)
                           throws UnsupportedEncodingException

Get a byte string from the bytes of a character string.

Parameters:

str - the character string

charset - the character set to use

Returns:

the byte string

Throws:

UnsupportedEncodingException - if the encoding is not supported

getBytes

public static ByteString getBytes(String str,
                  Charset charset)

Get a byte string from the bytes of a character string.

Parameters:

str - the character string

charset - the character set to use

Returns:

the byte string

getBytes

public static ByteString getBytes(ByteBuffer buffer)

Get a byte string from all remaining bytes of a ByteBuffer.

Parameters:

buffer - the buffer

Returns:

the byte string

getBytes

public static ByteString getBytes(ByteBuffer buffer,
                  int length)

Get a byte string from a ByteBuffer.

Parameters:

buffer - the buffer

length - the number of bytes to get

Returns:

the byte string

getBytes

public byte[] getBytes()

Get a copy of the bytes of this ByteString.

Returns:

the copy

getBytes

public void getBytes(byte[] dest)

Copy the bytes of this ByteString into the destination array. If the array is too short to hold the bytes, then only enough bytes to fill the array will be copied.

Parameters:

dest - the destination array

getBytes

public void getBytes(byte[] dest,
            int offs)

Copy the bytes of this ByteString into the destination array. If the array is too short to hold the bytes, then only enough bytes to fill the array will be copied.

Parameters:

dest - the destination array

offs - the offset into the destination array

getBytes

public void getBytes(byte[] dest,
            int offs,
            int len)

Copy the bytes of this ByteString into the destination array. If the array is too short to hold the bytes, then only enough bytes to fill the array will be copied.

Parameters:

dest - the destination array

offs - the offset into the destination array

len - the maximum number of bytes to copy

toString

public String toString(String charset)
                throws UnsupportedEncodingException

Convert this byte string to a standard string.

Parameters:

charset - the character set to use

Returns:

the standard string

Throws:

UnsupportedEncodingException - if the charset is unknown

length

public int length()

Get the number of bytes in this byte string.

Returns:

the number of bytes

substring

public ByteString substring(int offs)

Get the substring of this string starting at the given offset.

Parameters:

offs - the offset

Returns:

the substring

substring

public ByteString substring(int offs,
                   int len)

Get the substring of this string starting at the given offset.

Parameters:

offs - the offset

len - the substring length
