Reads a page of trackables based on some "equals" condition.

For example, someone wanting to find a page of trackables where "someId" is "123" would invoke this with something similar to: readPageWithEqualPredicate( contextInfo, page, "someId", "123", root -> root.get("someId"));

Parameters:: contextInfo - the context information of the request; page - the requested page to load; paramName - the name of the parameter being tested in the "equals" condition; paramValue - the value the parameter should have for the "equals" condition; fieldExpressionFunction - a function that generates an expression for the field to test in the "equals" condition; additionalPredicateFunctions - any additional predicates to add to the query
Returns:: a page of trackables

getManagedType
```
public Class<D> getManagedType()
```
Gets the type that the repository manages.

Returns:

the type that this repository manages
