| Constructor that will grab the token for us.

ACE_INLINE ACE_TP_Token_Guard::~ACE_TP_Token_Guard | ( | void |  | ) |

## Member Function Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL int ACE_TP_Token_Guard::acquire_read_token | ( | ACE_Time_Value * | max_wait_time = `0` | ) |

| A helper method that grabs the token for us, after which the thread that owns that can do some actual work.

int ACE_TP_Token_Guard::acquire_token | ( | ACE_Time_Value * | max_wait_time = `0` | ) |

| A helper method that grabs the token for us, after which the thread that owns that can do some actual work. This differs from acquire_read_token() as it uses acquire () to get the token instead of acquire_read ()

ACE_INLINE int ACE_TP_Token_Guard::is_owner | ( | void |  | ) |

| Returns whether the thread that created this object ownes the token or not.

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

ACE_INLINE void ACE_TP_Token_Guard::release_token | ( | void |  | ) |

| Release the token ..
