    • override

      public static Modules.OverriddenModuleBuilder override​(Module... modules)
      Returns a builder that creates a module that overlays override modules over the given modules. If a key is bound in both sets of modules, only the binding from the override modules is kept. This can be used to replace the bindings of a production module with test bindings: 
       Module functionalTestModule
     = Modules.override(new ProductionModule()).with(new TestModule());

      Prefer to write smaller modules that can be reused and tested without overrides.

      Parameters:
      modules - the modules whose bindings are open to be overridden

    • override

      public static <? extends Module> modules)
      Returns a builder that creates a module that overlays override modules over the given modules. If a key is bound in both sets of modules, only the binding from the override modules is kept. This can be used to replace the bindings of a production module with test bindings: 
       Module functionalTestModule
     = Modules.override(getProductionModules()).with(getTestModules());

      Prefer to write smaller modules that can be reused and tested without overrides.

      Parameters:
      modules - the modules whose bindings are open to be overridden

    • combine

      public static Module combine​(Module... modules)
      Returns a new module that installs all of modules.

    • combine

      public static <? extends Module> modules)
      Returns a new module that installs all of modules.
