Get the locators associated with this filter.
The locators are a sequence containing from one to four rti::core::Locator, used to specify the multicast address locators of an individual channel within a MultiChannel DataWriter.

The filter expression is 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.
The syntax of the expression will depend on the value of rti::core::policy::LocatorFilter::filter_name
