void Q922_Frame::SetInformationFieldSize ( PINDEX  size  ) 

PBoolean Q922_Frame::DecodeAnnexQ ( const BYTE *  buffer,
PINDEX  size 
)

Decodes a Q.922 frame from a given buffer, encoded as descibed in H.323 Annex Q. Returns the success of this operation

Reimplemented in H224_Frame.

PINDEX Q922_Frame::GetAnnexQEncodedSize (  )  const

Returns the size if encoded as described in H.323 Annex Q

PBoolean Q922_Frame::EncodeAnnexQ ( BYTE *  buffer,
PINDEX &  size 
) const

Encodes this Q.922 frame into the given buffer. On return, size contains the number of octets occupied in the buffer

PBoolean Q922_Frame::DecodeHDLC ( const BYTE *  data,
PINDEX  size 
)

Decodes a Q.922 frame from a given buffer. Returns the success of this operation

Reimplemented in H224_Frame.

PINDEX Q922_Frame::GetHDLCEncodedSize (  )  const

Returns an estimate of the encoded size. The receiver will use at most the size when encoding. Returns zero if encoding will fail.

PBoolean Q922_Frame::EncodeHDLC ( BYTE *  buffer,
PINDEX &  size 
) const

Encodes this Q.922 frame into the given buffer. On return, size contains the number of octets occupied in the buffer.

PBoolean Q922_Frame::EncodeHDLC ( BYTE *  buffer,
PINDEX &  size,
BYTE &  bitPosition 
) const

Encodes this Q.922 frame into the given buffer. On return, size contains the number of octets occupied in the buffer. Use bitPosition to determine at which bit the Q.922 FLAG sequence should begin. On return, bitPosition contains the bit at which the encoded stream ends. bitPosition shall be in the range 0-7, whereas 7 means that the FLAG sequence is encoded at byte boundaries
