Member Function Documentation

template<typename ObjType>

virtual ObjType* te::rp::AbstractFeeder< ObjType >::getCurrentObj ( ) const

pure virtual

Return the current sequence object.

Returns

A pointer to the current object or a null pointer if there are no object to return.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().

template<typename ObjType>

virtual unsigned int te::rp::AbstractFeeder< ObjType >::getCurrentOffset ( ) const

pure virtual

Return the index of the current object.

Returns

The index of the current object.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().

template<typename ObjType>

virtual unsigned int te::rp::AbstractFeeder< ObjType >::getObjsCount ( ) const

pure virtual

Return the total number of feeder objects.

Returns

The total number of feeder objects.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().

template<typename ObjType>

virtual bool te::rp::AbstractFeeder< ObjType >::moveNext ( )

pure virtual

Advances to the next sequence obeject.

Returns

true if the advance was completed or false if the objects sequence end was reached.

Note

This method can invalidate any pointer returned by getCurrentObj.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().

template<typename ObjType>

virtual bool te::rp::AbstractFeeder< ObjType >::moveTo ( const unsigned int  index )

pure virtual

Jump to the given object index.

Returns

true if the jump was completed or false on errors.

Note

This method can invalidate any pointer returned by getCurrentObj.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().

template<typename ObjType>

virtual void te::rp::AbstractFeeder< ObjType >::reset ( )

pure virtual

Reset the feeder to the first position (subsequent accesses will start from the first sequence obejct).

Note

This method can invalidate any pointer returned by getCurrentObj.

Implemented in te::rp::FeederConstRasterDirectory, te::rp::FeederConstRasterInfo, te::rp::FeederConstRasterVector, and te::rp::FeederConstRaster.

Referenced by te::rp::AbstractFeeder< const te::rst::Raster >::~AbstractFeeder().
