Member Function Documentation

void te::rst::RasterSummaryManager::add	(	const Raster *	raster,
		RasterSummary *	summary
	)

Adds a new entry in the summary manager.

Parameters

raster	The raster to be added.
summary	The raster summary of the respective raster. The manager will take its ownership.

Note

If the raster was already added, the summary will be replaced.

const te::rst::RasterSummary * te::rst::RasterSummaryManager::find

(

const Raster *

raster

)

const

It searches for a raster summary.

Parameters

raster

The raster to be found.

Returns

The calculated raster summary, or a null summary otherwise.

Definition at line 50 of file RasterSummaryManager.cpp.

References getConnInfoStr(), and m_rasterSummaries.

const te::rst::RasterSummary * te::rst::RasterSummaryManager::get	(	const Raster *	raster,
		const SummaryTypes	st,
		bool	readall = false
	)

It searches for a raster summary. If not found it creates the summary and returns it.

Parameters

raster	The raster to be found.
types	The desired types of summary to be calculated (min, max, ...).
readall	Force the reading the entire image (can be slow) for computing min and max values.

Returns

The calculated raster summary.
