Example 3 with PropertyAccess

use of org.apache.tapestry5.commons.services.PropertyAccess in project tapestry-5 by apache.

the class ExceptionUtils method findCause.

/**
 * Locates a particular type of exception, working its way down via any property that returns some type of Exception.
 * This is more expensive, but more accurate, than {@link #findCause(Throwable, Class)} as it works with older exceptions
 * that do not properly implement the (relatively new) {@linkplain Throwable#getCause() cause property}.
 *
 * @param t      the outermost exception
 * @param type   the type of exception to search for
 * @param access used to access properties
 * @return the first exception of the given type, if found, or null

the class TapestryModule method contributeApplicationInitializer.

/**
 * Adds a listener to the {@link org.apache.tapestry5.internal.services.ComponentInstantiatorSource} that clears the

            initializer.initializeApplication(context);
            // We don't care about the result, but this forces a load of the
            // service
            // at application startup, rather than on first request.

Example 5 with PropertyAccess

use of org.apache.tapestry5.commons.services.PropertyAccess in project tapestry-5 by apache.

the class HibernateModule method contributeValueEncoderSource.
