TransportMulticastSettingsSeq ^ DDS::ChannelSettings_t::multicast_settings

A sequence of DDS::TransportMulticastSettings_t used to configure the multicast addresses associated with a channel.

The sequence cannot be empty.

The maximum number of multicast locators in a channel is limited to four (A locator is defined by a transport alias, a multicast address and a port)

[default] Empty sequence (invalid value)

System::String ^ DDS::ChannelSettings_t::filter_expression

A logical expression used to determine the data that will be published in the channel.

If the expression evaluates to TRUE, a sample will be published on the channel.

An empty string always evaluates the expression to TRUE.

A NULL value is not allowed.

The syntax of the expression will depend on the value of DDS::MultiChannelQosPolicy::filter_name

The filter expression length (including NULL-terminated character) cannot be greater than DDS::DomainParticipantResourceLimitsQosPolicy::channel_filter_expression_max_length.
