Interface DialectSelector

All Superinterfaces:

LazyServiceResolver<Dialect>, Serializable, Service

All Known Implementing Classes:

AggregatedDialectSelector, DefaultDialectSelector

public interface DialectSelector
extends Service, LazyServiceResolver<Dialect>

Service which acts as a registry for named strategy implementations.

Strategies are more open ended than services, though a strategy managed here might very well also be a service. The strategy is any interface that has multiple, (possibly short) named implementations.

StrategySelector manages resolution of particular implementation by (possibly short) name via the StrategySelector.selectStrategyImplementor(java.lang.Class<T>, java.lang.String) method, which is the main contract here. As indicated in the docs of that method the given name might be either a short registered name or the implementation FQN. As an example, consider resolving the TransactionCoordinatorBuilder implementation to use. To use the JDBC-based TransactionCoordinatorBuilder the passed name might be either "jdbc" or "org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorBuilderImpl" (which is the FQN).

Strategy implementations can be managed by StrategySelector.registerStrategyImplementor(java.lang.Class<T>, java.lang.String, java.lang.Class<? extends T>) and StrategySelector.unRegisterStrategyImplementor(java.lang.Class<T>, java.lang.Class<? extends T>). Originally designed to help the OSGi use case, though no longer used there.

The service also exposes a general typing API via StrategySelector.resolveStrategy(java.lang.Class<T>, java.lang.Object) and StrategySelector.resolveDefaultableStrategy(java.lang.Class<T>, java.lang.Object, T) which accept implementation references rather than implementation names, allowing for a multitude of interpretations of said "implementation reference". See the docs for StrategySelector.resolveDefaultableStrategy(java.lang.Class<T>, java.lang.Object, T) for details.
