GridCollections (Ignite 2.17.0)

java.lang.Object
- org.apache.ignite.internal.util.GridCollections

```
public final class GridCollections
extends Object
```
Provides locked wrappers around given maps and collections. Since ReentrantLock performs a lot better than standard Java synchronization, these locked wrappers should perform better as their analogous methods in java.util.Collections class.
