ConstructorCache (AWS Java SDK :: Checksums 2.37.3 API)

java.lang.Object
- software.amazon.awssdk.checksums.internal.ConstructorCache

```
@SdkInternalApi
public final class ConstructorCache
extends Object
```
A cache that stores classes and exposes a method to retrieve its zero-argument constructor.
This cache stores weak references to loaded classes, allowing them to be garbage collected at any point.
Classes are loaded by first attempting to load it via the thread context ClassLoader (or system ClassLoader if the calling thread does not have one). If that fails, it will attempt using the ClassLoader that loaded ClassLoaderHelper.
If a class or its zero-argument constructor cannot be found, an empty result is returned.
