Parameters:

purge - If true, permanently delete the object AND its "ref" history from Orchestrate.

Returns:

The prepared delete request.

get

public <T> OrchestrateRequest<KvObject<T>> get(java.lang.Class<T> clazz)

get(Class).

Type Parameters:

T - The type to deserialize the result to.

Parameters:

clazz - Type information for marshalling objects at runtime.

Returns:

This KV resource.

get

public <T> OrchestrateRequest<KvObject<T>> get(@NonNull
                                               java.lang.Class<T> clazz,

                                               java.lang.String ref)

Fetch an object by key from the Orchestrate service.

Usage:

 
 KvObject<DomainObject> object =
         client.kv("someCollection", "someKey")
               .get(DomainObject.class)
               .get();

Parameters:

objectRef - The last known version of the stored object.

Returns:

This KV resource.
