Member Function Documentation

QString ImageModel::getTypeName (  )  const [inline, virtual]

Return the type of the model.

For display purposes only.

Reimplemented from SparseModel< ImagePoint >.

Definition at line 92 of file ImageModel.h.

virtual void ImageModel::toXml ( QTextStream &  out,
QString  indent = "",
QString  extraAttributes = "" 
) const [inline, virtual]

Stream this exportable object out to XML on a text stream.

Reimplemented from SparseModel< ImagePoint >.

Definition at line 94 of file ImageModel.h.

References SparseModel< PointType >::toXml().

virtual bool SparseModel< ImagePoint >::isOK (  )  const [inline, virtual, inherited]

Return true if the model was constructed successfully.

Classes that refer to the model should always test this before use.

Implements Model.

Definition at line 43 of file SparseModel.h.

virtual size_t SparseModel< ImagePoint >::getStartFrame (  )  const [virtual, inherited]

Return the first audio frame spanned by the model.

Implements Model.

virtual size_t SparseModel< ImagePoint >::getEndFrame (  )  const [virtual, inherited]

Return the last audio frame spanned by the model.

Implements Model.

virtual size_t SparseModel< ImagePoint >::getSampleRate (  )  const [inline, virtual, inherited]

Return the frame rate in frames per second.

Implements Model.

Definition at line 46 of file SparseModel.h.

virtual Model* SparseModel< ImagePoint >::clone (  )  const [virtual, inherited]

Return a copy of this model.

If the model is not editable, this may be effectively a shallow copy. If the model is editable, however, this operation must properly copy all of the model's editable data.

In general this operation is not useful for non-editable dense models such as waveforms, because there may be no efficient copy operation implemented -- for such models it is better not to copy at all.

Caller owns the returned value.

Implements Model.

virtual size_t SparseModel< ImagePoint >::getResolution (  )  const [inline, virtual, inherited]

Definition at line 55 of file SparseModel.h.

virtual void SparseModel< ImagePoint >::setResolution ( size_t  resolution  )  [virtual, inherited]

virtual bool SparseModel< ImagePoint >::isEmpty (  )  const [virtual, inherited]

Return whether the model is empty or not.

virtual size_t SparseModel< ImagePoint >::getPointCount (  )  const [virtual, inherited]

Get the total number of points in the model.

virtual PointList SparseModel< ImagePoint >::getPoints ( long  start,
long  end 
) const [virtual, inherited]

Get all of the points in this model between the given boundaries (in frames), as well as up to two points before and after the boundaries.

If you need exact boundaries, check the point coordinates in the returned list.

virtual PointList SparseModel< ImagePoint >::getPoints ( long  frame  )  const [virtual, inherited]

Get all points that cover the given frame number, taking the resolution of the model into account.

virtual const PointList& SparseModel< ImagePoint >::getPoints (  )  const [inline, virtual, inherited]

Get all points.

Definition at line 92 of file SparseModel.h.

virtual PointList SparseModel< ImagePoint >::getPreviousPoints ( long  frame  )  const [virtual, inherited]

Return all points that share the nearest frame number prior to the given one at which there are any points.

virtual PointList SparseModel< ImagePoint >::getNextPoints ( long  frame  )  const [virtual, inherited]

Return all points that share the nearest frame number subsequent to the given one at which there are any points.

virtual void SparseModel< ImagePoint >::clear (  )  [virtual, inherited]

Remove all points.

virtual void SparseModel< ImagePoint >::addPoint ( const ImagePoint point  )  [virtual, inherited]

Add a point.

virtual void SparseModel< ImagePoint >::deletePoint ( const ImagePoint point  )  [virtual, inherited]

Remove a point.

Points are not necessarily unique, so this function will remove the first point that compares equal to the supplied one using Point::Comparator. Other identical points may remain in the model.

virtual bool SparseModel< ImagePoint >::isReady ( int *  completion = 0  )  const [inline, virtual, inherited]

Return true if the model has finished loading or calculating all its data, for a model that is capable of calculating in a background thread.

The default implementation is appropriate for a thread that does not background any work but carries out all its calculation from the constructor or accessors.

If "completion" is non-NULL, this function should return through it an estimated percentage value showing how far through the background operation it thinks it is (for progress reporting). If it has no way to calculate progress, it may return the special value COMPLETION_UNKNOWN.
