Processor.Context (Hazelcast Root 5.4.0-SNAPSHOT API)

All Superinterfaces:

ProcessorMetaSupplier.Context, ProcessorSupplier.Context

All Known Implementing Classes:

TestProcessorContext

Enclosing interface:

Processor
```
public static interface Processor.Context
extends ProcessorSupplier.Context
```
Context passed to the processor in the init() call.

Since:

Jet 3.0

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`int`	`globalProcessorIndex()`	Returns the index of the processor among all the processors created for this vertex on all nodes: it's a unique cluster-wide index.
`int`	`localProcessorIndex()`	Returns the index of the processor among all the processors created for this vertex on a single node: it's a unique node-wide index.
`ILogger`	`logger()`	Return a logger for the processor
`default int[]`	`processorPartitions()`	Returns the slice of partitions for this processor.

- Method Detail
  - logger
```
@Nonnull
ILogger logger()
```
    Return a logger for the processor
    
    Specified by:
    
    logger in interface ProcessorMetaSupplier.Context
    
    Specified by:
    
    logger in interface ProcessorSupplier.Context
  - localProcessorIndex
```
int localProcessorIndex()
```
    Returns the index of the processor among all the processors created for this vertex on a single node: it's a unique node-wide index.
    The value is in the range [0...localParallelism-1].
  - globalProcessorIndex
```
int globalProcessorIndex()
```
    Returns the index of the processor among all the processors created for this vertex on all nodes: it's a unique cluster-wide index.
    The value is in the range [0...totalParallelism-1]. For example if there are 2 members in the cluster and local parallelism is 4, the processors on the 1st cluster member will have indexes 0..3 and on the second member they will have indexes 4..7.
  - processorPartitions
```
default int[] processorPartitions()
```
    Returns the slice of partitions for this processor. It distributes ProcessorSupplier.Context.memberPartitions() according to the ProcessorMetaSupplier.Context.localParallelism() and localProcessorIndex().
