Package org.springframework.lang
package org.springframework.lang
Common annotations with language-level semantics: nullability as well as JDK API indications.
These annotations sit at the lowest level of Spring's package dependency arrangement, even
lower than
org.springframework.util, with no Spring-specific concepts implied.
Used descriptively within the framework codebase. Can be validated by build-time tools (e.g. FindBugs or Animal Sniffer), alternative JVM languages (e.g. Kotlin), as well as IDEs (e.g. IntelliJ IDEA or Eclipse with corresponding project setup).
