Member Enumeration Documentation

enum SchedulingType

Available Scheduling Types.

Enumerator
kSerial	Any number of nodes of the same type can run in parallel,.
kGloballySerial	Node should be serialized locally, by chaining all nodes of this flag for sequential execution.
kUntrusted	Only one node of this type can be run at a time.
kLast	Node will do things that can't be predicted and nothing else can be scheduled to execute together with it. Just to mark the scheduling type count

Member Function Documentation

MPxCustomEvaluator evaluator

(

MStatus *

ReturnStatus

)

const

Get the evaluator responsible for this cluster node.

Parameters

[out]

ReturnStatus

Status flag

Returns

The evaluator for this object.

Status Codes:

• MS::kSuccess operation successful
• MS::kFailure operation failed (evaluator does not exist)

MEvaluationGraph ownerGraph

(

MStatus *

ReturnStatus

)

const

Get the graph that this node is a part of.

Parameters

[out]

ReturnStatus

Status flag

Returns

The cluster node's graph.

Status Codes:

• MS::kSuccess operation successful
• MS::kFailure operation failed (evaluator or graph do not exist)

MCustomEvaluatorClusterNode::SchedulingType schedulingType

(

MStatus *

ReturnStatus = NULL

)

const

Get the scheduling type for this cluster node.

Parameters

[out]

ReturnStatus

Status flag

Returns

Scheduling type

Status Codes:

• MS::kSuccess operation successful
• MS::kFailure operation failed (evaluator or graph do not exist)

Examples:

void evaluate

(

MStatus *

ReturnStatus = NULL

)

const

Evaluate the cluster of nodes.

Parameters

[out]

ReturnStatus

Status flag

Returns

None

Status Codes:

• MS::kSuccess operation successful
• MS::kFailure operation failed (evaluator or graph do not exist)

Examples:

void evaluateNode	(	const MEvaluationNode &	node,
		MStatus *	ReturnStatus
	)		const

Evaluate a single node in this cluster.

Note

In some cases, it can be useful when a user wants to change the order of evaluation of nodes inside the given cluster, or skip some nodes entirely. Note that this method should only be used on nodes that are members of the provided cluster.

Parameters

[in]	node	An evaluation node that is a member of the cluster
[out]	ReturnStatus	Status flag

Returns

None

Status Codes:

• MS::kSuccess operation successful
• MS::kFailure operation failed (evaluator or graph do not exist)

Examples:

const char * className ( )

static

Returns the name of this class.

Returns

The name of this class.
