String that might or might not be a compiler message key.The top qualifier.
This type qualifier indicates how much of an object has been fully initialized.

String type has unknown localization properties.Represents a
Method or Constructor expression whose run-time value is not known at compile time.Indicates that the
String type has an unknown property key property.Represents the top of the Regex qualifier hierarchy.
The value's signedness is not known to the Signedness Checker.
The top type for the Returns Receiver Checker's type system.
UnknownUnits is the top type of the type hierarchy.
UnknownVal is a type annotation indicating that the expression's value is not known at compile
type.
A special annotation intended solely for representing an unqualified type in the qualifier
hierarchy, as an argument to
SubtypeOf.value(), in a type qualifier declaration.The value is to be interpreted as unsigned.
A node for bitwise right shift operations with zero extension:
Denotes a reference that is untainted, i.e.
Declares that the field may not be accessed if the receiver is of the specified qualifier type
(or any supertype).
Implements the introduction rules for the Upper Bound Checker.

A type-checker for preventing arrays from being accessed with values that are too high.
A meta-annotation applied to the declaration of a type qualifier.
A literal value.
Contains the transfer functions for the upper bound type system, a part of the Index Checker.
A variable not known to have a relation to any sequence length.
Warns about array accesses that could be too high.
Exception type indicating a mistake by an end user in using the Checker Framework, such as
incorrect command-line arguments.
Class declaration to indicate the class does not override
equals(Object), and therefore
a.equals(b) and a == b behave identically.AnnotatedTypeFactory for the Value type system.
The Constant Value Checker is a constant propagation analysis: for each variable, it determines
whether that variable's value can be known at compile time.
