Method Detail

getType

public XrootdSecurityProtocol.BucketType getType()

serialize

public void serialize(org.jboss.netty.buffer.ChannelBuffer out)

deserialize

public static XrootdBucket deserialize(XrootdSecurityProtocol.BucketType type,
                       org.jboss.netty.buffer.ChannelBuffer buffer)
                                throws IOException

Deserialize an XrootdBucket. Depending on the BucketType, return an XrootdBucket of a specific subtype. The only type where the returned type is not a-priori known is kXRS_main, which can be encrypted. If it is encrypted, a binary (raw) bucket is returned, if it is not encyrpted, a list of contained buckets (nestedBuffer) is returned.

Parameters:

type - The type of the bucket that should be deserialized

buffer - The buffer containing the buckets

Returns:

The deserialized bucket

Throws:

IOException - Deserialization fails.

getSize

public int getSize()

Returns:

Length of the serialized bucket (in bytes)

toString

public String toString()

Overrides:

toString in class Object

writeInt

protected void writeInt(OutputStream out,
            int v)
                 throws IOException

Throws:

IOException
