DDS_Boolean | key_only_filter |
Indicates if the filter expression is based only on key fields. In this case, RTI Connext itself can cache the filtering results. More... | |
DDS_Boolean | writer_side_filter_optimization |
Indicates if the filter implementation can cache the filtering result for the provided expression. More... | |
Provides additional information about the filter expression passed to DDSWriterContentFilter::writer_compile.
It is used by the filter implementation to indicate to the middleware whether or not the DDSWriterContentFilter will cache the result of filter evaluation.
DDS_Boolean DDS_ExpressionProperty::key_only_filter |
Indicates if the filter expression is based only on key fields. In this case, RTI Connext itself can cache the filtering results.
When this field is set to DDS_BOOLEAN_TRUE, it indicates to RTI Connext that the filter expression is based only on key fields.
DDS_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 DDS_BOOLEAN_TRUE, RTI Connext will do no caching or explicit filter evaluation for the associated DDSDataReader. Instead, it will rely on the filter implementation to provide appropriate results.
