Annotation Interface ELEnvironment

@Documented @Retention(RUNTIME) @Target({TYPE,ANNOTATION_TYPE,FIELD,METHOD,PARAMETER}) public @interface ELEnvironment
Declares the compilation time environment shared by the expressions of the annotated type.

The environment is the compilation time counterpart of the jakarta.el.ELContext: it provides the variable types, the imported classes and the functions that are known when the expressions are compiled.

An environment declared on a field, a method or a parameter applies to the expressions declared on that member, on top of the environment of the class. The expressions declared on a method, or on one of its parameters, additionally see the parameters of the method as variables, under their names and with their declared types, unless a variable of the same name is declared explicitly.
