Class LegacyDefaultMemberAccessPolicy

All Implemented Interfaces:

public final class LegacyDefaultMemberAccessPolicy extends Object implements MemberAccessPolicy
Legacy blacklist based member access policy, used only to keep old behavior, as it can't provide meaningful safety. Do not use it if you allow untrusted users to edit templates! Use WhitelistMemberAccessPolicy then.

      public ClassMemberAccessPolicy forClass(Class<?> containingClass)
      Description copied from interface: MemberAccessPolicy
      Returns the ClassMemberAccessPolicy that encapsulates the member access policy for a given class. ClassMemberAccessPolicy implementations need not be thread-safe. Because class introspection results are cached, and so this method is usually only called once for a given class, the ClassMemberAccessPolicy instances shouldn't be cached by the implementation of this method.

      containingClass - The exact class of object from which members will be get in the templates.
    • isToStringAlwaysExposed

      public boolean isToStringAlwaysExposed()
      Description copied from interface: MemberAccessPolicy
      If this returns true, we won't invoke the probably more expensive lookup to figure out if Object.toString() (including its overridden variants) is exposed for a given object. If this returns false, then no such optimization is made. This method was introduced as Object.toString() is called frequently, as it's used whenever an object is converted to string, like printed to the output, and it's not even a reflection-based call (we just call Object.toString() in Java). So we try to avoid the overhead of a more generic method call.
