Method Detail

getSequenceNumber

public long getSequenceNumber()

getStructureSize

public int getStructureSize()

getBuffer

public SMBBuffer getBuffer()

The buffer from which this packet is read if it was a received packet

Overrides:

getBuffer in class SMBPacket<SMB2PacketData,SMB2PacketHeader>

Returns:

The buffer

write

public void write(SMBBuffer buffer)

writeTo

protected void writeTo(SMBBuffer buffer)

Write the message fields into the buffer, as specified in the [MS-SMB2] specification.

Parameters:

buffer -

read

protected final void read(SMB2PacketData packetData)
                   throws Buffer.BufferException

Specified by:

read in class SMBPacket<SMB2PacketData,SMB2PacketHeader>

Throws:

Buffer.BufferException

readMessage

protected void readMessage(SMBBuffer buffer)
                    throws Buffer.BufferException

Read the packet body, this should be implemented by the various packet types.

Parameters:

buffer -

Throws:

Buffer.BufferException

isSuccess

public final boolean isSuccess()

Whether this packet contains a success response or an error response

Returns:

true if the packet does not contain error data

isIntermediateAsyncResponse

public boolean isIntermediateAsyncResponse()

Check whether this packet is an intermediate ASYNC response

getMaxPayloadSize

public int getMaxPayloadSize()

Returns the maximum payload size of this packet. Normally this is the SINGLE_CREDIT_PAYLOAD_SIZE. Can be overridden in subclasses to support multi-credit messages.

Returns:

getCreditsAssigned

public int getCreditsAssigned()

setCreditsAssigned

public void setCreditsAssigned(int creditsAssigned)

getError

public SMB2Error getError()

getPacket

public SMB2Packet getPacket()

Method that can be overridden by Packet Wrappers to ensure that the original (typed) packet is obtainable.

Returns:

this

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
