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

Returns:

The buffer

getMessageStartPos

public int getMessageStartPos()

The start position of this packet in the getBuffer(). Normally this is 0, except when this packet was compounded.

Returns:

The start position of this received packet in the buffer

getMessageEndPos

public int getMessageEndPos()

THe end position of this packet in the getBuffer(). Normally this is the last written position, except when this packet was compounded.

Returns:

The end position of this received packet in 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].pdf specification.

Parameters:

buffer -

read

public final void read(SMBBuffer buffer)
                throws Buffer.BufferException

Throws:

Buffer.BufferException

readError

protected void readError(SMBBuffer buffer)
                  throws Buffer.BufferException

Throws:

Buffer.BufferException

readMessage

protected void readMessage(SMBBuffer buffer)
                    throws Buffer.BufferException

Read the message, this is only called in case the response is a success response according to #isSuccess(NtStatus)

Parameters:

buffer -

Throws:

Buffer.BufferException

isSuccess

protected boolean isSuccess(long statusCode)

Callback to verify whether the status is a success status. Some responses have error codes that should be treated as success responses.

Parameters:

status - The status to verify

Returns:

true is NtStatus.isSuccess()

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()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
