Examples with DataDomain org.apache.cayenne.access.DataDomain used on opensource projects

Example 1 with DataDomain

use of org.apache.cayenne.access.DataDomain in project cayenne by apache.

the class OsgiDataDomainProvider method get.

@Override
public DataDomain get() throws ConfigurationException {
    // here goes the class loading hack, temporarily setting application
    // bundle ClassLoader to be a thread ClassLoader for runtime to start.
    Thread thread = Thread.currentThread();
    ClassLoader activeCl = thread.getContextClassLoader();
    try {
        // using fake package name... as long as it is not
        // org.apache.cayenne, this do the right trick
        thread.setContextClassLoader(classLoaderManager.getClassLoader("com/"));
        DataDomain domain = super.get();
        EntityResolver entityResolver = domain.getEntityResolver();
        for (ObjEntity e : entityResolver.getObjEntities()) {
            // it is not enough to just call 'getObjectClass()' on
            // ClassDescriptor - there's an optimization that prevents full
            // descriptor resolving... so calling some other method...
            entityResolver.getClassDescriptor(e.getName()).getProperty("__dummy__");
            entityResolver.getCallbackRegistry();
        }
        // this triggers callbacks initialization using thread class loader
        entityResolver.getCallbackRegistry();
        return domain;
    } finally {
        thread.setContextClassLoader(activeCl);
    }
