Detailed Description

A helper class that helps grabbing, releasing and waiting on tokens for a thread that needs access to the reactor's token.

Constructor & Destructor Documentation

ACE_Dev_Poll_Reactor::Token_Guard::Token_Guard ( ACE_Dev_Poll_Reactor_Token &  token )

inline

Constructor that will grab the token for us.

ACE_Dev_Poll_Reactor::Token_Guard::~Token_Guard ( void  )

inline

Destructor. This will release the token if it hasn't been released till this point

ACE_Dev_Poll_Reactor::Token_Guard::Token_Guard ( void  )

private

Member Function Documentation

int ACE_Dev_Poll_Reactor::Token_Guard::acquire

(

ACE_Time_Value *

max_wait = 0

)

A helper method that acquires the token at a high priority, and does wake the current token holder.

int ACE_Dev_Poll_Reactor::Token_Guard::acquire_quietly

(

ACE_Time_Value *

max_wait = 0

)

A helper method that acquires the token 1) at a low priority, and 2) wait quietly for the token, not waking another thread. This is appropriate for cases where a thread wants to wait for and dispatch an event, not causing an existing waiter to relinquish the token.

int ACE_Dev_Poll_Reactor::Token_Guard::is_owner ( void  )

inline

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

void ACE_Dev_Poll_Reactor::Token_Guard::release_token ( void  )

inline

Release the token ..

Member Data Documentation

int ACE_Dev_Poll_Reactor::Token_Guard::owner_

private

Flag that indicate whether the thread that created this object owns the token or not. A value of 0 indicates that this class hasn't got the token (and hence the thread) and a value of 1 vice-versa.

ACE_Dev_Poll_Reactor_Token& ACE_Dev_Poll_Reactor::Token_Guard::token_

private

The Reactor token.
