Interface ConfigurationPersistenceStrategy2

  • All Known Subinterfaces:
    ConfigurationPersistenceStrategyMultiplexer
    @ConsumerType
public interface ConfigurationPersistenceStrategy2
    Defines how configuration data is stored in the configuration resource. This SPI allows application to define their own content structure and node types to be used for configuration data storage.

        Returns:
        true if the data was persisted. false if persisting the data was not accepted by this persistence strategy (in case of error throw an exception).

        Delete configuration or configuration collection data from repository using the inner-most context path as reference.
        Parameters:
