Parent Classes:

public DPIPortC<class DataT>

DPIImagePNMByteGreyC(FilenameC fn)

Constructor from filename.

DPIImagePNMByteGreyC(const IStreamC & strm)

Constructor from stream.

DPIPortBodyC<ImageC<ByteGreyValueT>> & Body()

Access body.

const DPIPortBodyC<ImageC<ByteGreyValueT>> & Body() const

Access body.

ImageC<ByteGreyValueT> Get()

Get next piece of data.

BooleanT Get(ImageC<ByteGreyValueT> & buff)

Try and get next piece of data.
If none, return FALSE. else put data into buff.

IntT GetArray(SArray1dC<ImageC<ByteGreyValueT>> & data)

Get an array of data from stream.
returns the number of elements processed.

DPIPortBaseBodyC & Body()

Access body.

const DPIPortBaseBodyC & Body() const

Access body.

const type_info & InputType() const

Get type of input port.

BooleanT IsGetReady() const

Is valid data.

BooleanT IsGetEOS() const

Is valid data.

BooleanT Discard()

Discard the next input datum.
returns true on success.

DPPortBodyC & Body()

Access body.

const DPPortBodyC & Body() const

Access body.

BooleanT IsAsync() const

Does port work asynchronously ??

DPPortC ConnectedTo() const

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

BooleanT 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.

BooleanT 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.

const DPEntityC & operator=(const DPEntityC & dat)

Assignment.

DPEntityBodyC & Body()

Access body.

const DPEntityBodyC & Body() const

Access body.

BooleanT Save(ostream & out) const

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

BooleanT Save(ostream & out) const

Save to ostream.

RCHandleAC<DPEntityBodyC> Copy() const

Creat a deep copy of this object.
protected:

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<DPEntityBodyC> & operator=(const RCHandleC<DPEntityBodyC> & oth)

Assignment.

BooleanT operator==(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

DPEntityBodyC & Body()

Direct access to body.

const DPEntityBodyC & Body() const

Constant access to body.
