Detailed Description

An abstract class for plugging in different Policy Validator mechanisms.

This class was moved form the PortableServer library. The Portable Serever library used this abstraction to add policy validators to for the policies in the POA. This class seems so much useful for passing policy information between different loaded libraries.

Member Function Documentation

void TAO_Policy_Validator::add_validator TAO_Policy_Validator *    validator

Adds a validator to the "chain of validators". The TAO_POA_Policy_Validator implements something that looks like a chain of responsability in which different member of the chain have the responsability of validating a given set of policies.

CORBA::Boolean TAO_Policy_Validator::legal_policy CORBA::PolicyType    type

Return whether the specified policy type is legal for the current configuration. This is needed since the user can potentially specify policies that are unknown to an validate () routine, and these need to be caught.

virtual CORBA::Boolean TAO_Policy_Validator::legal_policy_impl CORBA::PolicyType    type [protected, pure virtual]

void TAO_Policy_Validator::merge_policies TAO_Policy_Set &policies    ACE_ENV_ARG_DECL

Add/merge policies.

void TAO_Policy_Validator::validate TAO_Policy_Set &policies    ACE_ENV_ARG_DECL

Validate that the policies in the specified set are consistent and legal. Throw an appropriate exception if that is not the case.
