构造器详细资料

HexCodec

public HexCodec()

Creates a new codec with the default charset name Charsets.UTF_8

HexCodec

public HexCodec(Charset charset)

Creates a new codec with the given Charset.

参数:

charset - the charset.

从以下版本开始:

1.7

HexCodec

public HexCodec(String charsetName)

Creates a new codec with the given charset name.

参数:

charsetName - the charset name.

抛出:

UnsupportedCharsetException - If the named charset is unavailable

从以下版本开始:

1.7 throws UnsupportedCharsetException if the named charset is unavailable

方法详细资料

decode

public byte[] decode(byte[] array)
              throws CodecException

Converts an array of character bytes representing hexadecimal values into an array of bytes of those same values. The returned array will be half the length of the passed array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.

指定者:

decode 在接口中 BinaryCodec

指定者:

decode 在接口中 BinaryDecoder

指定者:

decode 在接口中 Decoder<byte[],byte[]>

指定者:

decode 在接口中 ICodec<byte[]>

参数:

array - An array of character bytes containing hexadecimal digits

返回:

A byte array containing binary data decoded from the supplied byte array (representing characters).

抛出:

CodecException - Thrown if an odd number of characters is supplied to this function

另请参阅:

Hex.decodeHex(char[])

encode

public byte[] encode(byte[] array)

Converts an array of bytes into an array of bytes for the characters representing the hexadecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

The conversion from hexadecimal characters to the returned bytes is performed with the charset named by getCharset().

指定者:

encode 在接口中 BinaryCodec

指定者:

encode 在接口中 BinaryEncoder

指定者:

encode 在接口中 Encoder<byte[],byte[]>

指定者:

encode 在接口中 ICodec<byte[]>

参数:

array - a byte[] to convert to Hex characters

返回:

A byte[] containing the bytes of the hexadecimal characters

从以下版本开始:

1.7 No longer throws IllegalStateException if the charsetName is invalid.

另请参阅:

Hex.encodeHex(byte[])

getCharset

public Charset getCharset()

Gets the charset.

返回:

the charset.

从以下版本开始:

1.7

getCharsetName

public String getCharsetName()

Gets the charset name.

返回:

the charset name.

从以下版本开始:

1.4

toString

public String toString()

Returns a string representation of the object, which includes the charset name.

覆盖:

toString 在类中 Object

返回:

a string representation of the object.
