Cut out a fixed length sequence.
Parent Classes:
Methods:
- DPSeqSliceC(IntT nframeLimit = -1,IntT startPos = -1)
-
Constructor
Start pos is ignored at the moment.
- DPIPortC<DataT> & Input()
-
Access input port.
- IntT FrameLimit() const
-
Get the frame limit.
- UIntT FrameCount() const
-
Access frame count.
- DataT Get()
-
Get next piece of data.
- BooleanT Get(DataT & buff)
-
Try and get next piece of data.
If none, return FALSE.
else put data into buff.
- IntT GetArray(SArray1dC<DataT> & data)
-
Get an array of data from stream.
returns the number of elements processed.
- const DPEntityC & operator=(const DPEntityC & dat)
-
Assignment.
- DPEntityBodyC & Body()
-
Access body.
- const DPEntityBodyC & Body() const
-
Access body.
- BooleanT Save(ostream & out) const
-
- 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.
- 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 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.
- 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.
- const DPEntityC & operator=(const DPEntityC & dat)
-
Assignment.
- DPEntityBodyC & Body()
-
Access body.
- const DPEntityBodyC & Body() const
-
Access body.
- BooleanT Save(ostream & out) const
-
