Member Function Documentation

long ACE::Monitor_Control::Monitor_Base::add_constraint ( const char *  expression,
Control_Action action = 0 

Add a constraint, returns a unique constraint id.

Thread-safe and guaranteed to be unique.

This is thread-safe on its own so we don't have to guard it here.

Since we know external key is unique, we don't check for failure.

void ACE::Monitor_Control::Monitor_Base::add_ref ( void  )
void ACE::Monitor_Control::Monitor_Base::add_to_registry ( const ACE_Time_Value time = ACE_Time_Value::zero)

Common to all monitors.

double ACE::Monitor_Control::Monitor_Base::average ( void  ) const

Calculate the average of the accumulated samples.

void ACE::Monitor_Control::Monitor_Base::clear ( void  )

Reset function.

Reimplemented in ACE::Monitor_Control::Size_Monitor.

void ACE::Monitor_Control::Monitor_Base::clear_i ( void  )

Overridden in some monitors (for example the OS monitors) where clearing requires monitor-specific actions.

Monitor_Base::CONSTRAINTS & ACE::Monitor_Control::Monitor_Base::constraints ( void  )

Get all constraints.

size_t ACE::Monitor_Control::Monitor_Base::count ( void  ) const

Returns the number of samples.

Monitor_Control_Types::NameList ACE::Monitor_Control::Monitor_Base::get_list ( void  ) const

Return the list or error msg if wrong type.

double ACE::Monitor_Control::Monitor_Base::last_sample ( void  ) const

Returns the most recent sample value.

double ACE::Monitor_Control::Monitor_Base::maximum_sample ( void  ) const

Returns the maximum sample value.

double ACE::Monitor_Control::Monitor_Base::minimum_sample ( void  ) const

Returns the minimum sample value.

const char * ACE::Monitor_Control::Monitor_Base::name ( void  ) const
void ACE::Monitor_Control::Monitor_Base::name ( const char *  new_name)
void ACE::Monitor_Control::Monitor_Base::receive ( double  data)

Updates the monitor's data if it is a numeric floating point.

void ACE::Monitor_Control::Monitor_Base::receive ( size_t  data)

Updates the monitor's data if it is an integer size.

void ACE::Monitor_Control::Monitor_Base::receive ( const Monitor_Control_Types::NameList data)

Updates the monitor's data if it is a string type.

Control_Action * ACE::Monitor_Control::Monitor_Base::remove_constraint ( const long  constraint_id)

Remove a constraint and return the associated control action, which may be shared, for deletion or further use.

void ACE::Monitor_Control::Monitor_Base::remove_from_registry ( void  )
void ACE::Monitor_Control::Monitor_Base::remove_ref ( void  )
void ACE::Monitor_Control::Monitor_Base::retrieve ( Monitor_Control_Types::Data data) const

Data accessors.

void ACE::Monitor_Control::Monitor_Base::retrieve_and_clear ( Monitor_Control_Types::Data data)
double ACE::Monitor_Control::Monitor_Base::sum_of_squares ( void  ) const

Calculate the sum of the squares of the samples.

Monitor_Control_Types::Information_Type ACE::Monitor_Control::Monitor_Base::type ( void  ) const

Return the type of this statistic.

void ACE::Monitor_Control::Monitor_Base::update ( void  )

Implemented by the most-derived class. Does the actual work of fetching the monitored value.

Overridden in derived classes.

Reimplemented in ACE::Monitor_Control::Size_Monitor.
