    The following tables list the members exposed by MQDecoder.

    Public Constructors
     NameDescription
    Public ConstructorMQDecoder ConstructorInstantiates a new MQ-decoder, with the specified number of contexts and initial states. The compressed bytestream is read from the 'iStream' object.

    Public Properties
     NameDescription
    Public PropertyByteInputBufferReturns the underlying 'ByteInputBuffer' from where the MQ coded input bytes are read.  
    Public PropertyNumCtxtsReturns the number of contexts in the arithmetic coder.

    Public Methods
     NameDescription
    Public MethodcheckPredTermChecks for past errors in the decoding process using the predictable error resilient termination. This works only if the encoder used the predictable error resilient MQ termination, otherwise it reports wrong results. If an error is detected it means that the MQ bit stream has been wrongly decoded or that the MQ terminated segment length is too long. If no errors are detected it does not necessarily mean that the MQ bit stream has been correctly decoded.  
    Public MethoddecodeSymbol  
    Public MethoddecodeSymbols  
    Public MethodnextSegmentResets the MQ decoder to start a new segment. This is like recreating a new MQDecoder object with new input data.  
    Public MethodresetCtxtResets a context to the original probability distribution.  
    Public MethodresetCtxtsResets a context to the original probability distribution. The original probability distribution depends on the actual implementation of the arithmetic coder or decoder.
