Class ServerRuntime

java.lang.Object
org.apache.cayenne.configuration.CayenneRuntime
org.apache.cayenne.configuration.server.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.

  • Constructor Details

    • 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.

      4.0

    • builder

      public static ServerRuntimeBuilder builder()
      Creates a builder of ServerRuntime.
      Returns:
      a builder of ServerRuntime.
      Since:
      4.0
    • 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.
      Since:
      4.0
    • performInTransaction

      public <T> T performInTransaction(TransactionalOperation<T> op, TransactionListener callback)
      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.

      4.0
    • performInTransaction

      public <T> T performInTransaction(TransactionalOperation<T> op, TransactionDescriptor descriptor)
      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.
      Type Parameters:
      T - result type
      Parameters:
      op - an operation to perform within the transaction.
      descriptor - describes additional transaction parameters
      Returns:
      a value returned by the "op" operation.
      Since:
      4.2
    • performInTransaction

      public <T> T performInTransaction(TransactionalOperation<T> op, TransactionListener callback, TransactionDescriptor descriptor)
      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.
      Type Parameters:
      T - returned value type
      Parameters:
      op - an operation to perform within the transaction.
      callback - a callback to notify as transaction progresses through stages.
      descriptor - describes additional transaction parameters
      Returns:
      a value returned by the "op" operation.

    • 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.
      Since:
      4.0
    • 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.
