Class LegacyDefaultMemberAccessPolicy

  • All Implemented Interfaces:
    MemberAccessPolicy
    public final class LegacyDefaultMemberAccessPolicy
extends java.lang.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.
    Since:
    2.3.30

    • Method Detail

      • forClass

        public ClassMemberAccessPolicy forClass​(java.lang.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.
        Specified by:
        forClass in interface MemberAccessPolicy
        Parameters:
        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.
