```
public static <E extends BaseEntity> com.github.collinalpert.lambda2sql.functions.SqlPredicate<E> getConstraints(Class<E> clazz)
```
    Retrieves a composition SqlPredicate for all constraints that have been added for a class or any superclass of it.
    
    Type Parameters:
    
    E - The type of the class to get the constraints for.
    
    Parameters:
    
    clazz - The class to retrieve query constraints from.
    
    Returns:
    
    A SqlPredicate describing the added constraints.
  - addConstraint
```
public static <E extends BaseEntity> void addConstraint(Class<E> clazz,
                                                        com.github.collinalpert.lambda2sql.functions.SqlPredicate<E> predicate)
```
    Adds a query constraint to a query made with a certain entity. This means that any query made with this entity will include this predicate.
    
    Type Parameters:
    
    E - The type of the entity.
    
    Parameters:
    
    clazz - The entity to add the constraint to.
    
    predicate - The constraint.
  - removeConstraints
```
public static void removeConstraints(Class<? extends BaseEntity> clazz)
```
    Removes all query constraints which were set for a specific entity.
    
    Parameters:
    
    clazz - The entity class to remove the constraints for.
