Examples of jodd.introspector.ClassDescriptor

jodd.introspector.ClassDescriptor
A descriptor class for all methods/fields/properties/constructors of a class. Static methods/fields are ignored.
Descriptors are 'lazy': various internal caches are created on first request.
Throughout this class, public members are defined as members defined with "public" keyword and declared in a public type. Public members declared by a non-public class is considered non-public because access to it from outside is prohibited by the java access control anyway.
Public members defined in public classes are always preferred even when we allow private/protected members and types to be visible. So if a non-public subtype and a public super type both have a field with the same name, the field in the public super type is always used.

   * @param type class type
   * @param staticMethodName static method name
   * @param arguments method argument types, may be <code>null</code>
