Constructor & Destructor Documentation

stor::QueueID::QueueID ( )

inline

A default-constructed QueueID is invalid; it can not be used to identify an actual queue.

Definition at line 83 of file QueueID.h.

                   :
    index_(0),
    policy_(enquing_policy::Max)
  { }

stor::QueueID::QueueID ( PolicyType  policy, size_t  index  )

inline

Create a QueueID used to identify a queue with enquing policy denoted by policy and with identifier index.

Definition at line 89 of file QueueID.h.

                                                  :
    index_(index),
    policy_(policy)
  { }

Member Function Documentation

size_t stor::QueueID::index ( ) const

inline

Return the index for this queue.

Definition at line 103 of file QueueID.h.

References index_.

Referenced by BeautifulSoup.PageElement::_invert(), and stor::operator<<().

  {
    return index_;
  }

bool stor::QueueID::isValid ( void  ) const

inline

Test for validity of a QueueID. Invalid QueueIDs do not represent the identity of any actual queue.

Definition at line 110 of file QueueID.h.

References stor::enquing_policy::Max, and policy_.

  {
    return policy_ != enquing_policy::Max;
  }

bool stor::QueueID::operator!= ( QueueID const &  other ) const

inline

operator!= is the negation of operator==.

Definition at line 133 of file QueueID.h.

References operator==().

  {
    return !( operator==(other));
  }

bool stor::QueueID::operator< ( QueueID const &  other ) const

inline

operator< induces a strict weak ordering, so that QueueID can be used as a key in std::map.

Definition at line 117 of file QueueID.h.

References index_, and policy_.

  {
    return policy_ == other.policy_
      ? index_ < other.index_
      : policy_ < other.policy_;
  }

bool stor::QueueID::operator== ( QueueID const &  other ) const

inline

operator== returns true if both the policies and indices are equal.

Definition at line 126 of file QueueID.h.

References index_, and policy_.

Referenced by operator!=().

  {
    return policy_ == other.policy_ && index_ == other.index_;
  }

QueueID::PolicyType stor::QueueID::policy ( ) const

inline

Return the tag for the queing policy of *this.

Definition at line 96 of file QueueID.h.
