方法详细资料

toBytes

public static byte[] toBytes(char[] chars)

参数:

chars - the character array to be converted to a byte array.

返回:

the byte array of the UTF-8 encoded character array.

toBytes

public static byte[] toBytes(char[] chars,
                             String encoding)
                      throws org.apache.shiro.codec.CodecException

参数:

chars - the character array to be converted to a byte array

encoding - the character encoding to use to when converting to bytes.

返回:

the bytes of the specified character array under the specified encoding.

抛出:

org.apache.shiro.codec.CodecException - if the JVM does not support the specified encoding.

toBytes

public static byte[] toBytes(String source)

Converts the specified source argument to a byte array with Shiro's PREFERRED_ENCODING.

参数:

source - the string to convert to a byte array.

返回:

the bytes representing the specified string under the PREFERRED_ENCODING.

toBytes

public static byte[] toBytes(String source,
                             String encoding)
                      throws org.apache.shiro.codec.CodecException

Converts the specified source to a byte array via the specified encoding, throwing a CodecException if the encoding fails.

参数:

source - the source string to convert to a byte array.

encoding - the encoding to use to use.

返回:

the byte array of the specified source with the given encoding.

抛出:

org.apache.shiro.codec.CodecException - if the JVM does not support the specified encoding.

toString

public static String toString(byte[] bytes)

Converts the specified byte array to a String using the PREFERRED_ENCODING.

参数:

bytes - the byte array to turn into a String.

返回:

the specified byte array as an encoded String (PREFERRED_ENCODING).

另请参阅:

toString(byte[], String)

toString

public static String toString(byte[] bytes,
                              String encoding)
                       throws org.apache.shiro.codec.CodecException

Converts the specified byte array to a String using the specified character encoding. This implementation does the same thing as new String(byte[], encoding), but will wrap any UnsupportedEncodingException with a nicer runtime CodecException, allowing you to decide whether or not you want to catch the exception or let it propagate.

参数:

bytes - the byte array to convert to a String

encoding - the character encoding used to encode the String.

返回:

the specified byte array as an encoded String

抛出:

org.apache.shiro.codec.CodecException - if the JVM does not support the specified encoding.

toChars

public static char[] toChars(byte[] bytes)

Returns the specified byte array as a character array using the PREFERRED_ENCODING.

参数:

bytes - the byte array to convert to a char array

返回:

the specified byte array encoded as a character array (PREFERRED_ENCODING).

toChars

public static char[] toChars(byte[] bytes,
                             String encoding)
                      throws org.apache.shiro.codec.CodecException

参数:

bytes - the byte array to convert to a String

encoding - the character encoding used to encode the bytes.

返回:

the specified byte array as an encoded char array

抛出:

org.apache.shiro.codec.CodecException - if the JVM does not support the specified encoding.
