public final class InterningChecker
extends BaseTypeChecker
A type-checker plug-in for the
Interned
qualifier that finds (and verifies the absence
of) equality-testing and interning errors.
The Interned
annotation indicates that a variable refers to the canonical instance of
an object, meaning that it is safe to compare that object using the "==" operator. This plugin
warns whenever "==" is used in cases where one or both operands are not Interned
.
Optionally, it suggests using "==" instead of ".equals" where possible.
