Method Detail

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 Modules.OverriddenModuleBuilder override(Iterable<? 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 Module combine(Iterable<? extends Module> modules)

Returns a new module that installs all of modules.
