ParameterImpl (OpenJPA Parent POM 4.1.1 API)

java.lang.Object
- org.apache.openjpa.persistence.ParameterImpl<T>

Type Parameters:

T - type of value carried by this parameter.

All Implemented Interfaces:

jakarta.persistence.Parameter<T>
```
public class ParameterImpl<T>
extends Object
implements jakarta.persistence.Parameter<T>
```
A user-defined parameter of a query. A parameter is uniquely identified within the scope of a query by either its name or integral position. The integral position refers to the integer key as specified by the user. The index of this parameter during execution in a datastore query may be different.
A value can be bound to this parameter. This behavior of a parameter carrying its own value is a change from earlier versions (where no explicit abstraction existed for a query parameter).

Since:

2.0.0
