DPOSPortBodyC()

Default constructor.

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.

bool Seek(UIntT off)

Seek to location in stream.
Returns false, if seek failed. (Maybe because its not implemented.) if an error occurered (Seek returned False) then stream position will not be changed.

bool DSeek(IntT off)

Delta Seek, goto location relative to the current one.
The default behavour of this functions is : Do some error checking then: Seek((UIntT)((IntT) Tell() + off)); if an error occurered (DSeek returned False) then stream position will not be changed.

UIntT Tell() const

Find current location in stream.
Defined as the index of the next object to be written or read. May return ((UIntT) (-1)) if not implemented.

UIntT Size() const

Find the total size of the stream. (assuming it starts from 0)
May return ((UIntT) (-1)) if not implemented.

UIntT Start() const

Find the offset where the stream begins, normally zero.
Defaults to 0

void PutEOS()

Put End Of Stream marker.

bool IsPutReady() const

Is port ready for data ?

const type_info & OutputType() const

Output type.

bool Save(ostream & out) const

Save to ostream.

bool Save(ostream & out) const

Save to ostream.

bool Save(BinOStreamC & out) const

Save to binary stream.

RCBodyVC & Copy() const

Creat a copy of this object.

bool IsAsync() const

Does port work asynchronously ?

bool Save(ostream & out) const

Save to ostream.

DPPortC ConnectedTo() 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.

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

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

bool Save(ostream & out) const

Save to stream 'out'.

bool Save(BinOStreamC & out) const

Save to binary stream 'out'.

RCBodyVC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

bool Save(ostream & out) const

Save to ostream.

bool Save(BinOStreamC & out) const

Save to binary stream.

RCBodyVC & Copy() const

Creat a copy of this object.

UIntT References() const

Access count of handles open to this object.

RCBodyC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

void IncRefCounter()

Increment reference counter.

bool DecRefCounter()

Decrement reference counter.
