public ReadVResponse(ReadVRequest request,
                     GenericReadRequestMessage.EmbeddedReadRequest[] requests,
                     io.netty.buffer.ByteBuf[] data,

                     int length,
                     boolean isIncomplete)

Method Detail

getRequest

public ReadVRequest getRequest()

Description copied from interface: XrootdResponse

Returns the request this is a response to.

Specified by:

getRequest in interface XrootdResponse<ReadVRequest>

getStatus

public int getStatus()

Description copied from interface: XrootdResponse

The xrootd response status code.

Specified by:

getStatus in interface XrootdResponse<ReadVRequest>

getSegments

public List<io.netty.buffer.ByteBuf> getSegments()

Returns the data segments of the response. Only the segments contained in this response are returned. The buffers returned are unmodifiable views of the actual data segments. Reference counts are shared and the caller should not release any reference to the returned buffers.

getSegmentLengths

public List<Integer> getSegmentLengths()

getIndex

public int getIndex()

Returns the starting index into the request read segments that this response addresses.

getLength

public int getLength()

Returns the number of segments contained in this response.

getDataLength

public int getDataLength()

Description copied from interface: XrootdResponse

Returns the length of the response body. This is the value of the dlen field in the Xrootd Server Response Format. This does not include the length of the 8 byte header.

Specified by:

getDataLength in interface XrootdResponse<ReadVRequest>

writeTo

public void writeTo(io.netty.channel.ChannelHandlerContext ctx,
                    io.netty.channel.ChannelPromise promise)

Description copied from interface: XrootdResponse

Writes the encoded message to the given channel context. Does not flush the channel. This is a destructive call and must at most be called once. Decreases the reference count by 1 and deallocates this object if the reference count reaches 0.

Specified by:

writeTo in interface XrootdResponse<ReadVRequest>

toString

public String toString()

Overrides:

toString in class Object

touch

public io.netty.util.ReferenceCounted touch(Object hint)

Specified by:

touch in interface io.netty.util.ReferenceCounted

deallocate

protected void deallocate()

Specified by:

deallocate in class io.netty.util.AbstractReferenceCounted
