/**
|
|
* Interface for determining locally available program elements, such as
|
|
* local variables and imports.
|
|
* Upon creation, a Scope is associated with a given program position;
|
|
* for example, a {@linkplain Tree tree node}. This position may be used to
|
|
* infer an enclosing method and/or class.
|
|
*
|
|
* <p>A Scope does not itself contain the details of the elements corresponding
|
|
* to the parameters, methods and fields of the methods and classes containing
|
|
* its position. However, these elements can be determined from the enclosing
|
|
* elements.
|
|
*
|
|
* <p>Scopes may be contained in an enclosing scope. The outermost scope contains
|
|
* those elements available via "star import" declarations; the scope within that
|
|
* contains the top level elements of the compilation unit, including any named
|
|
* imports.
