Create a MD5FileChecksum

方法详细资料

getAlgorithmName

public String getAlgorithmName()

The checksum algorithm name

指定者:

getAlgorithmName 在类中 FileChecksum

getLength

public int getLength()

The length of the checksum in bytes

指定者:

getLength 在类中 FileChecksum

getBytes

public byte[] getBytes()

The value of the checksum in bytes

指定者:

getBytes 在类中 FileChecksum

readFields

public void readFields(DataInput in)
                throws IOException

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

参数:

in - DataInput to deseriablize this object from.

抛出:

IOException

write

public void write(DataOutput out)
           throws IOException

Serialize the fields of this object to out.

参数:

out - DataOuput to serialize this object into.

抛出:

IOException

write

public static void write(org.znerd.xmlenc.XMLOutputter xml,
         MD5MD5CRC32FileChecksum that)
                  throws IOException

Write that object to xml output.

抛出:

IOException

valueOf

public static MD5MD5CRC32FileChecksum valueOf(Attributes attrs)
                                       throws SAXException

Return the object represented in the attributes.

抛出:

SAXException

toString

public String toString()

覆盖:

toString 在类中 Object
