Examples with Dependency org.elasticsearch.common.inject.spi.Dependency used on opensource projects

Example 1 with Dependency

use of org.elasticsearch.common.inject.spi.Dependency in project elasticsearch by elastic.

the class ProviderToInternalFactoryAdapter method get.

@Override
public T get() {
    final Errors errors = new Errors();
    try {
        T t = injector.callInContext(new ContextualCallable<T>() {

            @Override
            public T call(InternalContext context) throws ErrorsException {
                Dependency dependency = context.getDependency();
                return internalFactory.get(errors, context, dependency);
            }
        });
        errors.throwIfNewErrors(0);
        return t;
    } catch (ErrorsException e) {
        throw new ProvisionException(errors.merge(e.getErrors()).getMessages());
    }
}

Example 2 with Dependency

use of org.elasticsearch.common.inject.spi.Dependency in project elasticsearch by elastic.

the class ProviderMethodsModule method createProviderMethod.

<T> ProviderMethod<T> createProviderMethod(Binder binder, final Method method) {
    binder = binder.withSource(method);
    Errors errors = new Errors(method);
    // prepare the parameter providers
    Set<Dependency<?>> dependencies = new HashSet<>();
    List<Provider<?>> parameterProviders = new ArrayList<>();
    List<TypeLiteral<?>> parameterTypes = typeLiteral.getParameterTypes(method);
    Annotation[][] parameterAnnotations = method.getParameterAnnotations();
    for (int i = 0; i < parameterTypes.size(); i++) {
        Key<?> key = getKey(errors, parameterTypes.get(i), method, parameterAnnotations[i]);
        dependencies.add(Dependency.get(key));
        parameterProviders.add(binder.getProvider(key));
    }
    // Define T as the method's return type.
    @SuppressWarnings("unchecked") TypeLiteral<T> returnType = (TypeLiteral<T>) typeLiteral.getReturnType(method);
    Key<T> key = getKey(errors, returnType, method, method.getAnnotations());
    Class<? extends Annotation> scopeAnnotation = Annotations.findScopeAnnotation(errors, method.getAnnotations());
    for (Message message : errors.getMessages()) {
        binder.addError(message);
    }
    return new ProviderMethod<>(key, method, delegate, unmodifiableSet(dependencies), parameterProviders, scopeAnnotation);
}
