java.lang.Object
- org.apache.sysds.runtime.controlprogram.parfor.TaskPartitioner

Direct Known Subclasses:

TaskPartitionerFactoring, TaskPartitionerFixedsize
```
public abstract class TaskPartitioner
extends Object
```
This is the base class for all task partitioner. For this purpose it stores relevant information such as the loop specification (FROM, TO, INCR), the index variable and the task size. Furthermore, it declares two prototypes: (1) full task creation, (2) streaming task creation. Known implementation classes: TaskPartitionerFixedsize, TaskPartitionerFactoring
