interface — Checks whether a class object is an interface
is array — Checks whether a type is an array type
is reference type (Java), is class type (C#/CIL) — Checks whether a type is a reference type or a built-in type

A filter transforms a set by applying a boolean check to each member of the set individually; if the check succeeds, the member is included in the result set.

Like transforms, filters are applied to the front of a set expression. For example, interface is a filter that applies to classes and passes only those classes that are interfaces. So the set expression

interface classes in package "org.eclipse.core.runtime"

returns the interfaces that are in the org.eclipse.core.runtime package.
