Detailed Description

A helper class that helps grabbing, releasing and waiting on tokens for a thread that tries calling handle_events ().

In short, this class will be owned by one thread by creating on the stack. This class gives the status of the ownership of the token and manages the ownership

Constructor & Destructor Documentation

ACE_TP_Token_Guard::ACE_TP_Token_Guard ( ACE_Select_Reactor_Token &  token )

inline

Constructor that will grab the token for us.

ACE_TP_Token_Guard::~ACE_TP_Token_Guard ( void  )

inline

Destructor. This will release the token if it hasnt been released till this point

Member Function Documentation

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 ()

bool ACE_TP_Token_Guard::is_owner ( void  )

inline

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

void ACE_TP_Token_Guard::release_token ( void  )

inline

Release the token ..

Member Data Documentation

bool ACE_TP_Token_Guard::owner_

private

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

ACE_Select_Reactor_Token& ACE_TP_Token_Guard::token_

private

The Select Reactor token.
