System::Boolean DDS::ExpressionProperty::writer_side_filter_optimization

Indicates if the filter implementation can cache the filtering result for the provided expression.

When this field is set to true, RTI Connext will do no caching or explicit filter evaluation for the associated DDS::DataReader. Instead, it will rely on the filter implementation to provide appropriate results.
