result

public Type result()

Description copied from interface: Expr

Get the type that this expression will evaluate to. This type splits into a nominal and raw component. The nominal component retains name information and, as such, is incomplete. This means one should not use the nominal component for subtype testing; rather it should only be used for reporting information to the user (e.g. type errors, etc). The raw component represents the fully expanded type, and can safely be used for type testing. However, it can be rather long and cumbersome to read so should not be reported to the user.

Specified by:

result in interface Expr

Returns:

toString

public String toString()

Overrides:

toString in class Object
