```
public abstract class ParameterTypeVisitor
extends AbstractTraverseParentVisitor
```
This visitor calculates the type of an input parameter.
Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

```
    The InputParameter for which its type will be searched by visiting the query.
  - type
```
protected java.lang.Class<?> type
```
    The well defined type, which does not have to be calculated.
  - typeName
```
protected java.lang.String typeName
```
    The fully qualified name of the type.
  - visitedExpressions
```
protected final java.util.Set<Expression> visitedExpressions
