Class ServerRuntime


  • public class ServerRuntime
    extends CayenneRuntime
    Object representing Cayenne stack. Serves as an entry point to Cayenne for user applications and a factory of ObjectContexts. Implementation is a thin wrapper of the dependency injection container.

    The "Server" prefix in the name is in contrast to ROP "client" (that is started via ClientRuntime). So ServerRuntime is the default Cayenne stack that you should be using in all apps with the exception of client-side ROP.

      • ServerRuntime

        protected ServerRuntime​(Collection<Module> modules)
        Creates a server runtime configuring it with a standard set of services contained in ServerModule. CayenneServerModule is created with one or more 'configurationLocations'. An optional array of extra modules may contain service overrides and/or user services.

      • builder

        public static ServerRuntimeBuilder builder()
        Creates a builder of ServerRuntime.
        Returns:
        a builder of ServerRuntime.

      • builder

        public static ServerRuntimeBuilder builder​(String name)
        Creates a builder of ServerRuntime.
        Parameters:
        name - optional symbolic name of the created runtime.
        Returns:
        a named builder of ServerRuntime.
      • performInTransaction

        public <T> T performInTransaction​(TransactionalOperation<T> op)
        Runs provided operation wrapped in a single transaction. Transaction handling delegated to the internal TransactionManager. Nested calls to 'performInTransaction' are safe and attached to the same in-progress transaction. TransactionalOperation can be some arbitrary user code, which most often than not will consist of multiple Cayenne operations.

      • getDataDomain

        public DataDomain getDataDomain()
        Returns the main runtime DataDomain. Note that by default the returned DataDomain is the same as the main DataChannel returned by CayenneRuntime.getChannel(). Although users may redefine DataChannel provider in the DI registry, for instance to decorate this DataDomain with a custom wrapper.
      • getDataSource

        public DataSource getDataSource()
        Returns a default DataSource for this runtime. If no default DataSource exists, an exception is thrown.

      • getDataSource

        public DataSource getDataSource​(String dataNodeName)
        Provides access to the JDBC DataSource assigned to a given DataNode. A null argument will work if there's only one DataNode configured.

        Normally Cayenne applications don't need to access DataSource or any other JDBC code directly, however in some unusual conditions it may be needed, and this method provides a shortcut to raw JDBC.
