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.

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

Member Function Documentation

default_priority()

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.

flags()

long TAO_EC_Thread_Flags::flags ( ) const

inline

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

operator long()

TAO_EC_Thread_Flags::operator long ( ) const

inline

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

operator=()

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.

Note

The sched value only gets set if the scheduler is specified using symbols.

parse_symbols()

void TAO_EC_Thread_Flags::parse_symbols ( const char * syms )

protected

Value of THR_SCHED_*.

sched()

long TAO_EC_Thread_Flags::sched ( ) const

inline

Returns value of THR_SCHED_* used, or zero if unknown.

scope()

long TAO_EC_Thread_Flags::scope ( ) const

inline

Returns value of THR_SCOPE_* used, or zero if unknown.
