Detailed Description

template<class OWNER>
class proland::GetCurveDatasTask< OWNER >

GetCurveDatasTask is used for Layers that need "random" Tiles produced from an other Producer.

For example, if it requires all the data about a given Curve, it will need every tiles crossed by this Curve. It may also be used to prefetch CurveData (call to CurveDataFactory::getCurveData()). Prefetched CurveDatas will have to be accessed using the CurveDataFactory::findCurveData() method, and released via the CurveDataFactory::putCurveData() method (The release should be automatic).

	parent	the parent TaskGraph of task.
	owner	the layer that requires this GetCurveDatasTask.
	graphProducer	the GraphProducer for which we need the data.
	target	the TileProducer required for owner's tile creation.
	factory	the factory that creates the CurveDatas.
	level	the level of the created Tile.
	tx	the x coordinate of the created Tile.
