Examples with CascadeStyle org.hibernate.engine.spi.CascadeStyle used on opensource projects

Example 1 with CascadeStyle

use of org.hibernate.engine.spi.CascadeStyle in project hibernate-orm by hibernate.

the class Cascade method cascadeComponent.

private static void cascadeComponent(final CascadingAction action, final CascadePoint cascadePoint, final EventSource eventSource, final int componentPathStackDepth, final Object parent, final Object child, final CompositeType componentType, final Object anything) {
    Object[] children = null;
    final Type[] types = componentType.getSubtypes();
    final String[] propertyNames = componentType.getPropertyNames();
    for (int i = 0; i < types.length; i++) {
        final CascadeStyle componentPropertyStyle = componentType.getCascadeStyle(i);
        final String subPropertyName = propertyNames[i];
        if (componentPropertyStyle.doCascade(action)) {
            if (children == null) {
                // Get children on demand.
                children = componentType.getPropertyValues(child, eventSource);
            }
            cascadeProperty(action, cascadePoint, eventSource, componentPathStackDepth + 1, parent, children[i], types[i], componentPropertyStyle, subPropertyName, anything, false);
        }
    }
}

Example 2 with CascadeStyle

use of org.hibernate.engine.spi.CascadeStyle in project hibernate-orm by hibernate.

the class Property method getCascadeStyle.

private static CascadeStyle getCascadeStyle(String cascade) {
    if (cascade == null || cascade.equals("none")) {
        return CascadeStyles.NONE;
    } else {
        StringTokenizer tokens = new StringTokenizer(cascade, ", ");
        CascadeStyle[] styles = new CascadeStyle[tokens.countTokens()];
        int i = 0;
        while (tokens.hasMoreTokens()) {
            styles[i++] = CascadeStyles.getCascadeStyle(tokens.nextToken());
        }
        return new CascadeStyles.MultipleCascadeStyle(styles);
    }
}

Example 3 with CascadeStyle

use of org.hibernate.engine.spi.CascadeStyle in project hibernate-orm by hibernate.

the class Cascade method cascade.

/**
 * Cascade an action from the parent entity instance to all its children.  This
 * form is typically called from within cascade actions.
 *
 * @param persister The parent's entity persister
 * @param parent The parent reference.
 * @param anything Anything ;)   Typically some form of cascade-local cache
 * which is specific to each CascadingAction type
