Constructor & Destructor Documentation

te::rp::FeederConstRasterVector::FeederConstRasterVector

(

const std::vector< const te::rst::Raster * >

rasters

)

Constructor from a vector of input rasters pointers;.

Parameters

rasters

Input vector of rasters pointers.

Note

The given rasters must always be avaliable.

The feeder WILL NOT ACQUIRE the pointers.

Member Function Documentation

te::rst::Raster const * te::rp::FeederConstRasterVector::getCurrentObj ( ) const

virtual

Return the current sequence object.

Returns

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

Implements te::rp::FeederConstRaster.

Definition at line 52 of file FeedersRaster.cpp.

References m_currentOffset, and m_rasters.

unsigned int te::rp::FeederConstRasterVector::getCurrentOffset ( ) const

virtual

Return the index of the current object.

Returns

The index of the current object.

Implements te::rp::FeederConstRaster.

References m_currentOffset.

unsigned int te::rp::FeederConstRasterVector::getObjsCount ( ) const

virtual

Return the total number of feeder objects.

Returns

The total number of feeder objects.

Implements te::rp::FeederConstRaster.

Definition at line 89 of file FeedersRaster.cpp.

References m_rasters.

bool te::rp::FeederConstRasterVector::moveNext ( )

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.

Implements te::rp::FeederConstRaster.

bool te::rp::FeederConstRasterVector::moveTo ( const unsigned int  index )

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.

Implements te::rp::FeederConstRaster.

Definition at line 71 of file FeedersRaster.cpp.

References m_currentOffset, and m_rasters.

void te::rp::FeederConstRasterVector::reset ( )

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.

Implements te::rp::FeederConstRaster.
