Example 20 with GroovyRuntimeException

use of groovy.lang.GroovyRuntimeException in project groovy-core by groovy.

the class ConversionHandler method invoke.

/**
     * This method is a default implementation for the invoke method given in
     * InvocationHandler. Any call to a method with a declaring class that is
     * not Object, excluding toString() and default methods is redirected to invokeCustom.
     * <p>
     * Methods like equals and hashcode are called on the class itself instead
     * of the delegate because they are considered fundamental methods that should
     * not be overwritten. The toString() method gets special treatment as it is
     * deemed to be a method that you might wish to override when called from Groovy.
     * Interface default methods from Java 8 on the other hand are considered being
     * default implementations you don't normally want to change. So they are called
     * directly too
     * </p><p>
     * In many scenarios, it is better to overwrite the invokeCustom method where
     * the core Object related methods are filtered out.
     *</p>
     * @param proxy  the proxy
     * @param method the method
     * @param args   the arguments
     * @return the result of the invocation by method or delegate
     * @throws Throwable if caused by the delegate or the method
     * @see #invokeCustom(Object, Method, Object[])
