Method Detail

withFactories

public ModelRegistry withFactories(IEntityFactory<?,?,?>... factories)

Create a registry with the given models.

Parameters:

factories - Entity factories to be registered.

Returns:

this (Fluent interface)

newInstance

public IEntity newInstance(org.symphonyoss.s2.common.dom.json.ImmutableJsonObject jsonObject)
                    throws org.symphonyoss.s2.common.exception.InvalidValueException

Specified by:

newInstance in interface IModelRegistry

Throws:

org.symphonyoss.s2.common.exception.InvalidValueException

parseOneJsonObject

public static org.symphonyoss.s2.common.dom.json.ImmutableJsonObject parseOneJsonObject(Reader reader)
                                                                                 throws org.symphonyoss.s2.common.exception.InvalidValueException

Parse a single JSON object from the given Reader. This method does not do a partial read, it is expected that the contents of the Reader are a single object.

Parameters:

reader - The source of a JSON object.

Returns:

The parsed object as an ImmutableJsonObject.

Throws:

org.symphonyoss.s2.common.exception.InvalidValueException - If the input cannot be parsed or does not contain a single object.

parseOneJsonValue

public static org.symphonyoss.s2.common.dom.json.JsonValue<?,?> parseOneJsonValue(Reader reader)
                                                                           throws org.symphonyoss.s2.common.exception.InvalidValueException

Parse a single JSON value from the given Reader. This method does not do a partial read, it is expected that the contents of the Reader are a single value.

Parameters:

reader - The source of a JSON value.

Returns:

The parsed value as an (Immutable) JsonValue.

Throws:

org.symphonyoss.s2.common.exception.InvalidValueException - If the input cannot be parsed or does not contain a single object.
