Predicates

indirectlyInstantiates	Generalisation of `instantiates` that takes subtyping into account:
instantiates	Holds if the type `t` is a parameterization of `g`, where the `i`-th type parameter of `g` is instantiated to `arg`.

Classes

CollectionMethod	A method declared in a collection type.
CollectionMutation	A method call that mutates a collection.
CollectionMutator	A method that mutates the collection it belongs to.
CollectionQueryMethod	A method that queries the contents of a collection without mutating it.
CollectionSizeMethod	The `size` method on `java.util.Collection`.
CollectionType	A reference type that extends a parameterization of `java.util.Collection`.
FreshCollection	A `new` expression that allocates a fresh, empty collection.
