描述

该算子 clear_data_code_2d_modelclear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelClearDataCode2dModelclear_data_code_2d_model deletes a 2D data code model that was created by create_data_code_2d_modelcreate_data_code_2d_modelCreateDataCode2dModelCreateDataCode2dModelCreateDataCode2dModelcreate_data_code_2d_model or read_data_code_2d_modelread_data_code_2d_modelReadDataCode2dModelReadDataCode2dModelReadDataCode2dModelread_data_code_2d_model. All memory used by the model is freed. The handle of the model is passed in DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandledata_code_handle. After 该算子 call it is invalid.

For an explanation of the concept of the 2D data code reader see the introduction of chapter Identification / Data Code.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

This operator modifies the state of the following input parameter:

• DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandledata_code_handle

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