Method Detail

getBeanInfo

public static gw.internal.gosu.parser.GenericBeanInfo getBeanInfo(Class beanClass)

Introspect on a Java bean and learn all about its properties, exposed methods, below a given "stop" point.

If the BeanInfo class for a Java Bean has been previously Introspected based on the same arguments, then the BeanInfo class is retrieved from the BeanInfo cache.

Parameters:

beanClass - The bean class to be analyzed.

Throws:

IntrospectionException - if an exception occurs during introspection.

flushCaches

public static void flushCaches()

Flush all of the Introspector's internal caches. This method is not normally required. It is normally only needed by advanced tools that update existing "Class" objects in-place and need to make the Introspector re-analyze existing Class objects.

getDeclaredMethods

public static Method[] getDeclaredMethods(Class clz)

getRootCause

public static Throwable getRootCause(Throwable throwable)

Traverse exception chain to return the root cause.

Parameters:

throwable - The top-level exception in the chain

Returns:

The root (or top-level if none chained)
