SchedulerPolicy::SchedulerPolicy Constructor

Constructs a new scheduler policy and populates it with values for policy keys supported by Concurrency Runtime schedulers and the Resource Manager.

SchedulerPolicy();

SchedulerPolicy(
   size_t _PolicyKeyCount,
   ...
);

SchedulerPolicy(
   const SchedulerPolicy& _SrcPolicy
);

Parameters

  • _PolicyKeyCount
    The number of key/value pairs that follow the _PolicyKeyCount parameter.

  • _SrcPolicy
    The source policy to copy.

Remarks

The first constructor creates a new scheduler policy where all policies will be initialized to their default values.

The second constructor creates a new scheduler policy that uses a named-parameter style of initialization. Values after the _PolicyKeyCount parameter are supplied as key/value pairs. Any policy key which is not specified in this constructor will have its default value. This constructor could throw the exceptions invalid_scheduler_policy_key, invalid_scheduler_policy_value or invalid_scheduler_policy_thread_specification.

The third constructor is a copy constructor. Often, the most convenient way to define a new scheduler policy is to copy an existing policy and modify it using the SetPolicyValue or SetConcurrencyLimits methods.
