| ~TAO_Policy_Set (void)
| Destructor. More...

| Get the values (if any) for the policies in <types>, if <types> is an empty list the method returns *all* the current policies. More...

| Obtain a single policy. More...
CORBA::Policy_ptr | get_cached_const_policy (TAO_Cached_Policy_Type type) const
| Obtain a cached policy for speedy lookups. This method just returns a const reference to the policy to avoid obtaining a lock to increment the reference count. As such, it can only be used for single threaded cases or cases where the policies cannot be removed such as at the object and thread level scopes. This method is most likely not appropriate for accessing policies at the ORB level scope in any situation. More...

## Detailed Description

The policy manager implementation.

This class is used to implement both the CORBA::PolicyManager and the CORBA::PolicyCurrent interfaces.

## Constructor & Destructor Documentation

ACE_INLINE TAO_Policy_Set::TAO_Policy_Set | ( | TAO_Policy_Scope | scope | ) |

| Creates a TAO_Policy_Set that has a given scope. The scope is used to determinate whether or not a given policy can be set for the given Policy Manager Implementation.

TAO_Policy_Set::TAO_Policy_Set | ( | const TAO_Policy_Set & | rhs | ) |

TAO_Policy_Set::~TAO_Policy_Set | ( | void |  | ) |

| Destructor.

## Member Function Documentation

void TAO_Policy_Set::cleanup_i | ( | ACE_ENV_SINGLE_ARG_DECL |  | ) | `[private]`

| Remove and destroy all the policy objects owned by this policy manager.

ACE_INLINE CORBA::Boolean TAO_Policy_Set::compatible_scope | ( | TAO_Policy_Scope | policy_scope | ) | const`[private]`

| Utility method to determine if a policy's scope is compatible with ours.

void TAO_Policy_Set::copy_from | ( | TAO_Policy_Set *source | ACE_ENV_ARG_DECL | ) |

| Copy the state from <source>, it uses the copy() operator to obtain independent copies of all the policies.

CORBA::Policy_ptr TAO_Policy_Set::get_cached_const_policy | ( | TAO_Cached_Policy_Type | type | ) | const

| Obtain a cached policy for speedy lookups. This method just returns a const reference to the policy to avoid obtaining a lock to increment the reference count. As such, it can only be used for single threaded cases or cases where the policies cannot be removed such as at the object and thread level scopes. This method is most likely not appropriate for accessing policies at the ORB level scope in any situation.

CORBA::Policy_ptr TAO_Policy_Set::get_cached_policy | ( | TAO_Cached_Policy_Type | type | ) |

| Obtain a single cached policy.

CORBA::Policy_ptr TAO_Policy_Set::get_policy | ( | CORBA::PolicyType policy | ACE_ENV_ARG_DECL_WITH_DEFAULTS | ) |

| Obtain a single policy.

ACE_INLINE CORBA::Policy * TAO_Policy_Set::get_policy_by_index | ( | CORBA::ULong | index | ) |

| Returns the policy at the specified index. CORBA::Policy::_nil () is returned if the policy doesn't exist.

CORBA::PolicyList * TAO_Policy_Set::get_policy_overrides | ( | const CORBA::PolicyTypeSeq &types | ACE_ENV_ARG_DECL | ) |

| Get the values (if any) for the policies in <types>, if <types> is an empty list the method returns *all* the current policies.

ACE_INLINE CORBA::ULong TAO_Policy_Set::num_policies | ( | void |  | ) | const

TAO_Policy_Set TAO_Policy_Set::operator= | ( | const TAO_Policy_Set & |  | ) | `[private]`

void TAO_Policy_Set::set_policy | ( | const CORBA::Policy_ptr policy | ACE_ENV_ARG_DECL | ) |

| Utility method to set a single policy.

void TAO_Policy_Set::set_policy_overrides | ( | const CORBA::PolicyList & | policies,
|  | CORBA::SetOverrideType set_add | ACE_ENV_ARG_DECL
| ) |

| Modify the list of policies to include <policies>. If <set_add> is CORBA::SET_OVERRIDE then we replace all the old policies. If it is CORBA::ADD_OVERRIDE we simply add the policies in <policies>. No attempt is made to validate the policies for consistency.
