Put data.

IntT PutArray(const SArray1dC<DataT> & data)

Put an array of data to stream.

void PutEOS()

Put End Of Stream marker.

bool IsGetReady() const

Is some data ready ?
true = yes.

DataT Get()

Get next piece of data.
May block if not ready, or it will return a constructed with the default constructor.

bool Get(DataT & buff)

Get next piece of data.
May block if not ready, or it will return a constructed with the default constructor.

IntT GetArray(SArray1dC<DataT> & data)

Get data directly.

bool Save(ostream & out) const

Save to ostream.

DListC<DPIPortBaseC> IPorts() const

Input ports.

DListC<DPOPortBaseC> OPorts() const

Output ports

DataT Get()

Get next piece of data.
May block if not ready, or it could throw an DataNotReadyC exception. NB. This function MUST be provided by client class.

bool Get(DataT & buff)

Try and get next piece of data.
This may not NOT block, if no data is ready it will return false, and not set buff. NB. The default version of this function uses the Get() method defined above and so need not be provided by derived classes.

IntT GetArray(SArray1dC<DataT> & data)

Get an array of data from stream.
returns the number of elements succesfully processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

const type_info & InputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

bool Discard()

Discard the next input datum.

bool Put(const DataT &)

Put data.
This function MUST be provided by client class.

IntT PutArray(const SArray1dC<DataT> & data)

Put an array of data to stream.
returns number of elements processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

const type_info & OutputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

StringC OpName() const

Op type name.

DListC<DPIPlugBaseC> IPlugs() const

Input plugs.

DListC<DPOPlugBaseC> OPlugs() const

Output plugs

DListC<DPIPortBaseC> IPorts() const

Is this port connected to another ?
If not returns invalid handle.

bool GetAttr(const StringC & attrName,StringC & attrValue)

Get a stream attribute.
Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.
