clear_ocr_class_knnT_clear_ocr_class_knnClearOcrClassKnnClearOcrClassKnn (Operator)

Name

clear_ocr_class_knnT_clear_ocr_class_knnClearOcrClassKnnClearOcrClassKnn — Clear an OCR classifier.

Signature

clear_ocr_class_knn( : : OCRHandle : )

clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnn clears the OCR classifier given by OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle that was created with create_ocr_class_knncreate_ocr_class_knnCreateOcrClassKnnCreateOcrClassKnnCreateOcrClassKnn and frees all memory required for the classifier. After calling clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnn, the classifier can no longer be used. The handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle 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:

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle

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

Parameters

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle (input_control, state is modified) ocr_knn → (handle)

Handle of the OCR classifier.

Result

If OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle is valid, the operator clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
