Detailed Description

Synchronized raster raster band blocks manager.

Constructor & Destructor Documentation

te::rst::SynchronizedBandBlocksManager::SynchronizedBandBlocksManager ( )

te::rst::SynchronizedBandBlocksManager::~SynchronizedBandBlocksManager ( )

void te::rst::SynchronizedBandBlocksManager::free ( )

Note: Free all allocated internal resources and go back to the initial state.

void* te::rst::SynchronizedBandBlocksManager::getBlockPointer	(	unsigned int	band,
		unsigned int	x,
		unsigned int	y
	)

Returns a pointer to the required data block.

Parameters

unsigned int te::rst::SynchronizedBandBlocksManager::getMaxNumberOfCacheBlocks ( ) const

inline

The maximum number of cache blocks.

te::rst::Raster* te::rst::SynchronizedBandBlocksManager::getRaster ( ) const

Returns the associated raster.

RasterSynchronizer* te::rst::SynchronizedBandBlocksManager::getSynchronizer ( ) const

inline

Return a pointer to the assotiated synchronizer instance or NULL if there is none.

bool te::rst::SynchronizedBandBlocksManager::initialize	(	RasterSynchronizer &	sync,
		const unsigned char	maxMemPercentUsed
	)

Initialize this instance to an initial state.

Parameters

sync	The synchronized used by this instance.
maxMemPercentUsed	The maximum free memory percentual to use valid range: [1:100].

Note: For the case where using the write raster access policy: The use of multiple cached blocks can cause deadlocks if multiple threads are locking blocks needed by other threads, use it with caution!

bool te::rst::SynchronizedBandBlocksManager::initialize	(	const unsigned int	maxNumberOfCacheBlocks,
		RasterSynchronizer &	sync
	)

Initialize this instance to an initial state.

Parameters

sync	The synchronized used by this instance.
maxNumberOfCacheBlocks	The maximum number of cache blocks.

Note: For the case where using the write raster access policy: The use of multiple cached blocks can cause deadlocks if multiple threads are locking blocks needed by other threads, use it with caution!

void te::rst::SynchronizedBandBlocksManager::initState ( )

private

Initialize this instance to an initial state.

bool te::rst::SynchronizedBandBlocksManager::isInitialized ( ) const

inline

Returns true if this instance is initialized.
