Description

The operator clear_bar_code_modelclear_bar_code_modelClearBarCodeModelClearBarCodeModelclear_bar_code_model deletes a bar code model that was created by create_bar_code_modelcreate_bar_code_modelCreateBarCodeModelCreateBarCodeModelcreate_bar_code_model. All memory used by the model is freed. The handle of the model is passed in BarCodeHandleBarCodeHandleBarCodeHandlebarCodeHandlebar_code_handle, which is invalid after the operator call.

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:

• BarCodeHandleBarCodeHandleBarCodeHandlebarCodeHandlebar_code_handle

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

BarCodeHandleBarCodeHandleBarCodeHandlebarCodeHandlebar_code_handle (input_control, state is modified)  barcode(-array) → HBarCode, HTupleMaybeSequence[HHandle]HTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the bar code model.

Result

The operator clear_bar_code_modelclear_bar_code_modelClearBarCodeModelClearBarCodeModelclear_bar_code_model returns the value 2 ( H_MSG_TRUE) if a valid handle was passed and the referred bar code model can be freed correctly. Otherwise, an exception will be raised.
