> This is an implementation of JEP JDK-8315129: Module Import Declarations > (Preview). Please see the JEP for details: > https://bugs.openjdk.org/browse/JDK-8315129 > > It is mostly straightforward - the module imports are parsed, and then > expanded to import-on-demand in `TypeEnter`. > There is a few notable aspects, however: > - the AST node for import (`JCImport`) is holding the imported element as a > field access, because so far, the imported element always had to have a '.' > (even for import-on-demand). But for module imports, it is permissible to > import from a module whose name does not have a dot (`import module m;`). The > use of field access for ordinary import seems very useful, so I preferred to > keep that, and created a new internal-only AST node for module imports. There > is still only one public API AST node/interface, so this is purely an > implementation choice. > - JShell now supports module imports as well; and the default, implicit, > script is changed to use it to import all of `java.base` if preview is > enabled. It is expected that the default would be changed if/when the module > imports feature is finalized.
