Detailed Description

Parse thread flags from string to a long.

Encapsulate flags used for creating threads with ACE_OS::thr_create and ACE_Task::activate.

Note

On platforms that do not support the thread schedulers, the ACE OS adaptation layer preserves the symbols for THR_SCHED_*, but defines them as zero. Thus, on such platforms, setting a scheduler in the flags, then inquiring for the scheduler type will yield the same result as an unknown or unset scheduler.

This should really be part of ACE or ACE_OS, and maybe someday it will, but right now it's not.

Member Function Documentation

long TAO_EC_Thread_Flags::default_priority

(

)

const

Return an acceptable default priority for the scheduler returned by sched().

Returns

the priority, or ACE_DEFAULT_THREAD_PRIORITY if the scheduler is unknown.

long TAO_EC_Thread_Flags::flags ( void  ) const

inline

Returns numeric equivalent of the thread flags suitable for passing to ACE_Task::activate.

TAO_EC_Thread_Flags::operator long ( ) const

inline

Synonym for flags(), i.e., syntactic sugar.

const TAO_EC_Thread_Flags& TAO_EC_Thread_Flags::operator= ( const char *  symbolic_flags )

inline

Assign a new set of symbolic flags, setting flags, scope, and sched as possible.

The flags can be symbolic, separated by the vertical bar ('|'). In case a platform supports a creation flag not available symbolically, the user can specify a numeric value any place a symbol could be used.

long TAO_EC_Thread_Flags::sched ( ) const
