Param (eo-runtime 0.29.5 API)

java.lang.Object
- org.eolang.Param

```
public final class Param
extends Object
```
Param of an object (convenient retrieval mechanism).
The job of the utility object is to help our EO objects retrieve attributes from other objects and from their own \rho (owners). On top of retrieval this object also does simple type checking. When an attribute is expected to be of some type, we use strong(Class). This method will throw a runtime exception if types don't match. If just a simple retrieval without type checking is necessary, just use the method weak().
