Class OperatorExecutor2

java.lang.Object
  org.esa.beam.framework.gpf.experimental.OperatorExecutor2

public class OperatorExecutor2
extends Object

This executor triggers the computation of all tiles that the bands of the target product of the given operator have. The computation of these tiles is may be parallelized to use all available CPUs (cores) using the JAI TileScheduler.

Requirements:
1. Receive raster data for all bands for a requested tile size.
2. Deterministic vs. Non-deterministic Op/Graph Execution (asynchronous, synchronous)
3. Efficient computation of single pixels (may not be implemented here, but in MultiLevelImage)
4. Immediate Execution
5. Configurable with respect to e.g. parallelism, execution order

Since:

BEAM 4.9
