EntitySpec (Apache Brooklyn)

java.lang.Object
- brooklyn.basic.AbstractBrooklynObjectSpec<T,EntitySpec<T>>
- - brooklyn.entity.proxying.EntitySpec<T>

Type Parameters:
T - The type of entity to be created

All Implemented Interfaces:

java.io.Serializable
```
public class EntitySpec<T extends Entity>
extends AbstractBrooklynObjectSpec<T,EntitySpec<T>>
```
Gives details of an entity to be created. It describes the entity's configuration, and is reusable to create multiple entities with the same configuration. To create an EntitySpec, it is strongly encouraged to use create(Class) etc. Users who need to implement this are strongly encouraged to extend EntitySpec.

Constructor Detail

EntitySpec

public EntitySpec(java.lang.Class<T> type)

Method Detail

create
```
public static <T extends Entity> EntitySpec<T> create(java.lang.Class<T> type)
```
Creates a new EntitySpec instance for an entity of the given type. The returned EntitySpec can then be customized.

Parameters:
type - An Entity interface

create
```
public static <T extends Entity,U extends T> EntitySpec<T> create(java.lang.Class<T> type,
                                                  java.lang.Class<U> implType)
```
Creates a new EntitySpec instance for an entity of the given type. The returned EntitySpec can then be customized.

Parameters:
type - An Entity interface
implType - An Entity implementation, which implements the type interface

create
```
public static <T extends Entity> EntitySpec<T> create(java.util.Map<?,?> config,
                                      java.lang.Class<T> type)
```
Creates a new EntitySpec instance with the given config, for an entity of the given type. This is primarily for groovy code; equivalent to EntitySpec.create(type).configure(config).

Parameters:
config - The spec's configuration (see configure(Map)).
type - An Entity interface

create
```
public static <T extends Entity> EntitySpec<T> create(EntitySpec<T> spec)
```
Copies entity spec so its configuration can be overridden without modifying the original entity spec.

newInstance

public static <T extends Entity> EntitySpec<T> newInstance(java.lang.Class<T> type)

getType
```

Returns:
The type of the object (or significant interface)

getId
```

@Nullable

getAdditionalInterfaces
```
public java.util.Set<java.lang.Class<?>> getAdditionalInterfaces()
```
Returns:
Additional interfaces (other than just getType()) that this entity implements; important for when accessing entity through a proxy to determine which interfaces the proxy exposes.
