Examples with PersistenceWeaver org.eclipse.persistence.internal.jpa.weaving.PersistenceWeaver used on opensource projects

Example 1 with PersistenceWeaver

use of org.eclipse.persistence.internal.jpa.weaving.PersistenceWeaver in project eclipselink by eclipse-ee4j.

the class EntityManagerSetupImpl method predeployCompositeMembers.

        // if both composite and composite member weavings enabled copy class details from member's weaver to composite's one.
        if (enableWeaving && containedWeaver != null) {
            this.weaver.getClassDetailsMap().putAll(containedWeaver.getClassDetailsMap());

Example 2 with PersistenceWeaver

use of org.eclipse.persistence.internal.jpa.weaving.PersistenceWeaver in project eclipselink by eclipse-ee4j.

    PersistenceWeaver tw = null;

    } catch (Exception e) {
        fail(getName() + " failed: " + e.toString());
    }
    assertNotNull("could not build TopLinkWeaver", tw);
    return tw;
