Detailed Description

This filter implements the fastdds IContentFilterFactory interface. It is designed specifically as a workaround for https://github.com/eProsima/Fast-DDS/issues/3296. This implementation allows the user to register content filters for key annotated dynamic types, where a sample is dropped unless the key members match the user-provided values.

◆ create_content_filter()

eprosima::fastrtps::types::ReturnCode_t ddsfmu::detail::CustomKeyFilterFactory::create_content_filter	(	const char *	filter_class_name,
		const char *	type_name,
		const eprosima::fastdds::dds::TopicDataType *	data_type,

		eprosima::fastdds::dds::IContentFilter *&	filter_instance
	)

inlineoverride

Updating the filter will not delete the old one. Once a reader is added, it cannot be removed.

Parameters

filter_class_name	Custom filter name
type_name	Data type name
data_type	Data type pointer, which must be DynamicPubSubType*
filter_parameters	Parameters required by the filter
filter_instance	Instance of the filter to be evaluated

Returns: eprosima::fastrtps::types::ReturnCode_t::RETCODE_BAD_PARAMETER if the requirements for creating the ContentFilteredTopic using this factory are not met eprosima::fastrtps::types::ReturnCode_t::RETCODE_OK if the ContentFilteredTopic is correctly created

◆ delete_content_filter()

eprosima::fastrtps::types::ReturnCode_t ddsfmu::detail::CustomKeyFilterFactory::delete_content_filter	(	const char *	filter_class_name,
		eprosima::fastdds::dds::IContentFilter *	filter_instance
