Member Data Documentation

TransportMulticastSettingsSeq multicast_settings

Initial value:

=
        new TransportMulticastSettingsSeq()

A sequence of com.rti.dds.infrastructure.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)

String 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 com.rti.dds.infrastructure.MultiChannelQosPolicy.filter_name

The filter expression length (including NULL-terminated character) cannot be greater than com.rti.dds.infrastructure.DomainParticipantResourceLimitsQosPolicy.channel_filter_expression_max_length.
