GridSegmentationProcessor (Ignite 2.17.0)

All Superinterfaces:

GridComponent, GridProcessor

All Known Implementing Classes:

GridOsSegmentationProcessor
```
public interface GridSegmentationProcessor
extends GridProcessor
```
Kernal processor responsible for checking network segmentation issues.
Segment checks are performed by segmentation resolvers Each segmentation resolver checks segment for validity, using its inner logic. Typically, resolver should run light-weight single check (i.e. one IP address or one shared folder). Compound segment checks may be performed using several resolvers.

- Method Detail
  - isValidSegment
```
boolean isValidSegment()
```
    Performs network segment check.
    This method is called by discovery manager in the following cases:
    
    Before discovery SPI start.
    
    When other node leaves topology.
    
    When other node in topology fails.
    
    Periodically (see IgniteConfiguration.getSegmentCheckFrequency()).
    Returns:
    
    True if segment is correct.
