Field Details

FACTORIES

static final List<ResourceFactory> FACTORIES

The factories as found by the ServiceLoader.

Method Details

create

static <T extends Resource> T create(ResourceType<T> type,
 Project project,
 Object... args)

Returns a new resource with the given type, passing the given arguments to the constructor of the resource. The implementation uses ServiceLoader to find a ResourceFactory that creates the resource, i.e. that does not return Optional.empty() when <T>newResource(org.jdrupes.builder.api.ResourceType<T>,org.jdrupes.builder.api.Project,java.lang.Object...) is called.

Type Parameters:

T - the generic resource type

Parameters:

type - the resource type

project - the project

args - the additional arguments

Returns:

the resource

create

static <T extends Resource> T create(ResourceType<T> type,
 Object... args)

Short for create(type, null, args).

Type Parameters:

T - the generic resource type

Parameters:

type - the resource type

args - the additional arguments

Returns:

the resource

newResource

<T extends Resource> Optional<T> newResource(ResourceType<T> type,
 Project project,
 Object... args)

Returns a new resource of the given type if the factory instance can create it.

Type Parameters:

T - the generic resource type

Parameters:

type - the resource type

project - the project

args - the additional arguments

Returns:

the result. Optional.empty() if the resource cannot be created by the factory instance.
