The Checker Framework enhances Java's type system to make it more powerful and useful. This lets software developers detect and prevent errors in their Java programs. The Checker Framework includes compiler plug-ins ("checkers") that find bugs or verify their absence. It also permits you to write your own compiler plug-ins.

There is a newer version: 3.42.0-eisop4

/**
 * This annotation is used on a formal parameter to indicate that the parameter may be returned, but
 * it is not otherwise leaked. (A parameter is leaked if it is stored in a field where it could be
 * accessed later, and in that case this annotation would not apply.)
 *
 * 

For example, the receiver parameter of {@link StringBuffer#append(String s)} is annotated as * {@code @LeakedToResult}, because the method returns the updated receiver. * *

This annotation is currently trusted, not checked. * * @see NonLeaked * @checker_framework.manual #aliasing-checker Aliasing Checker */ // This is a type qualifier because of a Checker Framework limitation (Issue 383), but its hierarchy // is ignored. Once the stub parser gets updated to read non-type-qualifiers annotations on stub // files, this annotation won't be a type qualifier anymore. @Documented @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.TYPE_USE}) @SubtypeOf({NonLeaked.class}) public @interface LeakedToResult {}
