SizeFunctions (Stardog-9.0.0 API)

java.lang.Object
- com.complexible.common.base.SizeFunctions

```
public final class SizeFunctions
extends java.lang.Object
```
Implementation of size computation for commonly used object types. The result will typically be an approximation rather than an exact amount. Speed is more important than accuracy since this utility is primarily used to adjust the number of elements in a cache.
