Interface JpaProject

All Superinterfaces:

IAdaptable, JpaModel, Model

All Known Subinterfaces:

EclipseLinkJpaProject, JpaProject2_0

public interface JpaProject
extends JpaModel

A JPA project is associated with an Eclipse project (and its corresponding Java project). It holds the resource model that corresponds to the various JPA-related resources (the persistence.xml file, its mapping files [orm.xml], and the Java source files). It also holds the context model that represents the JPA metadata, as derived from spec-defined defaults, Java source code annotations, and XML descriptors.

To retrieve the JPA project corresponding to an Eclipse project:

 IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject("Foo Project");
 JpaProject jpaProject = (JpaProject) project.getAdapter(JpaProject.class);
 

This is a non-blocking call; and as a result it will return null if the JPA project is currently under construction. Use a JPA project reference to retrieve a JPA project in a blocking fashion that will return a JPA project once it has been constructed.

See org.eclipse.jpt.jpa.core/plugin.xml:org.eclipse.core.runtime.adapters.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:

2.0

discoversAnnotatedClasses

boolean discoversAnnotatedClasses()

Return whether the JPA project will not generate error messages for any annotated classes that are not listed in the persistence.xml file or one of its mapping files. If this flag is set to false, error messages will be generated for all of the annotated classes that are not explicitly listed. The JPA project always "discovers" annotated classes and allows the user to reference them throughout the model; this flag simply controls whether the error messages are generated during validation.

This is a user-specified preference that is probably only helpful when deploying to a JavaSE environment. The JPA spec says annotated classes are to be discovered automatically in a JavaEE environment; while the managed persistence classes must be explicitly listed in a JavaSE environment: "A list of all named managed persistence classes must be specified in Java SE environments to insure portability". This flag allows Dali to behave consistently with the user's JPA implementation, which may allow "discovery" in a JavaSE environment (e.g. EclipseLink). This setting can also be used when the user wants to explicitly list classes, even when the classes are "discovered" by the JPA implementation.

setDiscoversAnnotatedClasses

void setDiscoversAnnotatedClasses(boolean discoversAnnotatedClasses)

Set whether the JPA project will not generate error messages for any annotated classes that are not listed in the persistence.xml file or one of its mapping files.
