Struct ValueObjectFactory

pub struct ValueObjectFactory { /* private fields */ }

Factory for creating value objects from schema definitions and JSON values.

The factory maintains a registry of constructors and can dynamically create appropriate value objects based on attribute definitions.

Implementations

impl ValueObjectFactory

pub fn new() -> Self

Create a new factory with default constructors registered.

pub fn create_value_object( &self, definition: &AttributeDefinition, value: &Value, ) -> ValidationResult<Box<dyn ValueObject>>

Create a value object from a schema definition and JSON value.

pub fn get_expected_type(&self, attribute_name: &str) -> Option<AttributeType>

Get the expected attribute type for a given attribute name.

pub fn register_constructor( &mut self, constructor: Box<dyn ValueObjectConstructor>, )

Register a custom constructor.

pub fn validate_composite_rules( &self, objects: &[Box<dyn ValueObject>], ) -> ValidationResult<()>

Validate composite rules across multiple value objects.

pub fn has_constructors(&self) -> bool

Check if the factory has any constructors registered.

pub fn create_value_objects_from_json( &self, definitions: &[AttributeDefinition], json_obj: &Map<String, Value>, ) -> ValidationResult<Vec<Box<dyn ValueObject>>>

Create a collection of value objects from a JSON object.
