Class TypeResolver

java.lang.Object
  org.hibernate.type.TypeResolver

All Implemented Interfaces:

Serializable

public class TypeResolver
extends Object
implements Serializable

Acts as the contract for getting types and as the mediator between BasicTypeRegistry and TypeFactory.

Constructor Summary

TypeResolver()

TypeResolver(BasicTypeRegistry basicTypeRegistry, TypeFactory typeFactory)

Method Summary

BasicType	basic(String name) Locate a Hibernate basic type given (one of) its registration names; if scoped to a SessionFactoryImplementor, the scoped type is returned.
TypeFactory	getTypeFactory()
Type	heuristicType(String typeName) See heuristicType(String, Properties)
Type	heuristicType(String typeName, Properties parameters) Uses heuristics to deduce the proper Type given a string naming the type or Java class.
void	registerTypeOverride(BasicType type)
void	registerTypeOverride(CompositeUserType type, String[] keys)
void	registerTypeOverride(UserType type, String[] keys)
TypeResolver	scope(SessionFactoryImplementor factory)

basic

public BasicType basic(String name)

Locate a Hibernate basic type given (one of) its registration names; if scoped to a SessionFactoryImplementor, the scoped type is returned.

Parameters:

name - The registration name

Returns:

The registered type

heuristicType

public Type heuristicType(String typeName)
                   throws MappingException

See heuristicType(String, Properties)

Parameters:

typeName - The name (see heuristic algorithm discussion on heuristicType(String, Properties)).

Returns:

The deduced type; may be null.

Throws:

MappingException - Can be thrown from heuristicType(String, Properties)

heuristicType

public Type heuristicType(String typeName,
                          Properties parameters)
                   throws MappingException

Uses heuristics to deduce the proper Type given a string naming the type or Java class.

The search goes as follows:

1. search for a basic type with 'typeName' as a registration key
2. look for 'typeName' as a class name and
   1. if it names a Type implementor, return an instance
   2. if it names a CompositeUserType or a UserType, return an instance of class wrapped intot the appropriate Type adapter
   3. if it implements Lifecycle, return the corresponding entity type
   4. if it implements Serializable, return the corresponding serializable type

Parameters:

typeName - The name (see heuristic algorithm above).

parameters - Any parameters for the type. Only applied if built!

Returns:

The deduced type; may be null.

Throws:

MappingException - Indicates a problem attempting to resolve 'typeName' as a Class
