Description
get_params_ocr_class_knnget_params_ocr_class_knnGetParamsOcrClassKnnGetParamsOcrClassKnnget_params_ocr_class_knn returns the parameters of an OCR
classifier that were specified when the classifier was created with
create_ocr_class_knncreate_ocr_class_knnCreateOcrClassKnnCreateOcrClassKnncreate_ocr_class_knn. This is particularly useful if the
classifier was read with read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn. The output of
get_params_ocr_class_knnget_params_ocr_class_knnGetParamsOcrClassKnnGetParamsOcrClassKnnget_params_ocr_class_knn can, for example, be used to check
whether a character to be read is contained in the classifier. For

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

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