Finding implementations of an interface in Eclipse

Question

I'm looking at the following method.

public void setRecordValidator(Validator recordValidator) {
    this.recordValidator = recordValidator;
}

In this case class Validator is an interface. I'm not sure what kind of object to pass on to the method since I'm not sure what classes actually implement Validator.

The question is how can I view classes that implement Validator in Eclipse?

Answer 1

Click on Validator somewhere in the code and press Ctrl+T - this will open the Type Hierarchy popup.

Answer 2

Rightclick on Validator -> Declarations -> Project

Rightclick on Validator in the search result -> Implementations -> Project
