PreAllocatedArray (Apache Accumulo Core 2.0.0 API)

java.lang.Object
- org.apache.accumulo.core.util.PreAllocatedArray<T>

All Implemented Interfaces:

Iterable<T>
```
public class PreAllocatedArray<T>
extends Object
implements Iterable<T>
```
An ArrayList implementation that represents a type-safe pre-allocated array. This should be used exactly like an array, but helps avoid type-safety issues when mixing arrays with generics. The iterator is unmodifiable.
