Class NestedBucketBuffer

java.lang.Object

org.dcache.xrootd.security.XrootdBucket

org.dcache.xrootd.security.NestedBucketBuffer

public class NestedBucketBuffer
extends XrootdBucket

Format of a NestedBucketBuffer: - int32 BucketType (usually kXRS_main) - int32 len - char[4] protocol (\0 padded) - int32 step (e.g. kXGS_cert) -- int32 BucketType (first nested bucket) -- int32 len -- byte[len] bucket-content -- int32 kXRS_none -- int32 BucketType (second nested bucket) ... - kXRS_none

                  Map<XrootdSecurityProtocol.BucketType,XrootdBucket> nestedBuckets)

Method Detail

deserialize

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

Deserialize the NestedBucketBuffer. Retrieve all the buckets and recursively deserialize them. Also, retrieve the protocol information and the step.

Parameters:

type - The type of the bucket (usually kXRS_main)

buffer - The buffer containing the nested bucket buffer

Returns:

Deserialized buffer

Throws:

IOException - Deserialization fails

getNestedBuckets

public Map<XrootdSecurityProtocol.BucketType,XrootdBucket> getNestedBuckets()

Returns:

the list of XrootdBuckets nested in this buffer

getStep

public int getStep()

getProtocol

public String getProtocol()

serialize

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

Overrides:

serialize in class XrootdBucket

getSize

public int getSize()

Overrides:

getSize in class XrootdBucket

Returns:

Length of the serialized bucket (in bytes)

toString

public String toString()

Overrides:

toString in class XrootdBucket
