Define Documentation

#define ACE_ES_DISPATCHING_MODULE   ACE_ES_Priority_Dispatching

ACE_ES_DISPATCHING_MODULE determines what Dispatching Module is used by the channel. ACE_ES_Dispatching_Base is a null dispatcher that can be used to build an EFD.

Variable Documentation

const long ACE_ES_BITMASK_DESIGNATOR = 12

const long ACE_ES_CONJUNCTION_DESIGNATOR = 8

const long ACE_ES_DISJUNCTION_DESIGNATOR = 9

const int ACE_ES_DISPATCH_REQUEST_MEMORY_POOL = 1024

const long ACE_ES_EVENT_ACT = 2

const long ACE_ES_EVENT_ANY = 0

const int ACE_ES_EVENT_CONTAINER_MEMORY_POOL = 1024

This is the chunk size of the cached allocator for ACE_ES_Event_Container.

const long ACE_ES_EVENT_DEADLINE_TIMEOUT = 6

const long ACE_ES_EVENT_INTERVAL_TIMEOUT = 5

const int ACE_ES_EVENT_MEMORY_POOL = 1024

const long ACE_ES_EVENT_NOTIFICATION = 3

const long ACE_ES_EVENT_SHUTDOWN = 1

const long ACE_ES_EVENT_SOURCE_ANY = 0

const long ACE_ES_EVENT_TIMEOUT = 4

const long ACE_ES_EVENT_UNDEFINED = 16

const long ACE_ES_GLOBAL_DESIGNATOR = 7

const long ACE_ES_LOGICAL_AND_DESIGNATOR = 11

const long ACE_ES_MASKED_TYPE_DESIGNATOR = 13

const int ACE_ES_MAX_CONSUMERS_PER_SUPPLIER = 100

Max number of consumers that one supplier can have subscribed to one type of event (including source-only). This restriction is very lightweight since subscription lists are dynamic. This constant is only used for ACE_ES_Simple_Set in Event_Channel.* for disconnecting consumers. Since these objects are allocated off the stack, we can increase this number without requiring more heap memory.

const int ACE_ES_MAX_SUBSCRIPTIONS = 32

This is the number of events a consumer can subscribe to.

const long ACE_ES_NEGATION_DESIGNATOR = 10

const long ACE_ES_NULL_DESIGNATOR = 14

const long ACE_Scheduler_MAX_PREEMPTION_PRIORITY = 0

Max preemption priority.

const long ACE_Scheduler_MAX_PRIORITIES = 5

The max number of priorities provided by the target platform. Todo: This should be defined in ACE (somehow) and only mapped here to some variables (and even that is doubtful).

const u_long ACE_Scheduler_MAX_SUB_PRIORITY

Initial value: ACE_Message_Block::MB_USER - 1 This is the maximum sub priority.

const long ACE_Scheduler_MIN_PREEMPTION_PRIORITY

Initial value: ACE_Scheduler_MAX_PRIORITIES - 1 The minimum preemption priority.

const u_long ACE_Scheduler_MIN_SUB_PRIORITY

Initial value: ACE_Message_Block::MB_NORMAL This is the minimum sub priority.

const TimeBase::TimeT ACE_Scheduler_Rates[ACE_Scheduler_MAX_PRIORITIES]

Initial value: { 250000, 500000, 1000000, 2000000, 10000000 }

const int THREADS_PER_DISPATCH_QUEUE = 1

This is the number of threads spawned for *each* priority queue in the channel's Dispatching Module. This is used by the channel when creating the dispatch module.
