参数签名

描述

clear_serialized_itemclear_serialized_itemClearSerializedItemClearSerializedItemClearSerializedItemclear_serialized_item deletes a serialized item, which is passed by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basics of serialization). If a serialized item is created only by a data pointer, it will not be deleted. Such a data pointer, that points to the beginning of serialized item can be created by 该算子 get_serialized_item_ptrget_serialized_item_ptrGetSerializedItemPtrGetSerializedItemPtrGetSerializedItemPtrget_serialized_item_ptr. After calling clear_serialized_itemclear_serialized_itemClearSerializedItemClearSerializedItemClearSerializedItemclear_serialized_item, the handle of the serialized item becomes invalid.
