clear_class_knnclear_class_knnClearClassKnnClearClassKnn (Operator)

Name

clear_class_knnclear_class_knnClearClassKnnClearClassKnn — Clear a k-NN classifier.

clear_class_knnclear_class_knnClearClassKnnClearClassKnnClearClassKnn clears the k-NN classifiers given in KNNHandleKNNHandleKNNHandleKNNHandleKNNHandle. After calling clear_class_knnclear_class_knnClearClassKnnClearClassKnnClearClassKnn, KNNHandleKNNHandleKNNHandleKNNHandleKNNHandle becomes invalid.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

This operator modifies the state of the following input parameter:

KNNHandleKNNHandleKNNHandleKNNHandleKNNHandle

The value of this parameter may not be shared across multiple threads without external synchronization.

Parameters

KNNHandleKNNHandleKNNHandleKNNHandleKNNHandle (input_control, state is modified) class_knn → (integer)

Handle of the k-NN classifier.

Result

If the parameters are valid, the operator clear_class_knnclear_class_knnClearClassKnnClearClassKnnClearClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.

Possible Predecessors
