Detailed Description

Utility class implementing an atomic boolean on top of an int32.

The mysys lib does not support atomic booleans.

Constructor & Destructor Documentation

atomic_boolean()

atomic_boolean::atomic_boolean ( bool  value = false )

inline

Constructs a new atomic_boolean.

Parameters

value

The value to initialize the boolean with.

Member Function Documentation

is_set()

bool atomic_boolean::is_set ( bool  value = true )

inline

Checks if the atomic boolean has a certain value.

if used without an argument checks if the atomic boolean is on.

Parameters

value

the value to check for

Return values

true	the atomic boolean value matches the argument value
false	the atomic boolean value is different from the argument value

set()

void atomic_boolean::set ( bool  new_value )

inline

Sets a new value for the atomic boolean.

Parameters

new_value

value to set
