<<extension>> Specifies the data query that defines a com.rti.dds.subscription.TopicQuery
The query format is similar to the expression and parameters of a com.rti.dds.subscription.QueryCondition or a com.rti.dds.topic.ContentFilteredTopic, as described in com.rti.dds.domain.DomainParticipant.create_contentfilteredtopic_with_filter.
There are two special queries:
Object copy_from | ( | Object | src | ) |
This is the implementation of the Copyable
interface. This method will perform a deep copy of src
This method could be placed into TopicQuerySelectionTypeSupport
rather than here by using the -noCopyable
option to rtiddsgen.
src | The Object which contains the data to be copied. |
this
. NullPointerException | If src is null. |
ClassCastException | If src is not the same type as this . |
String filter_class_name = null |
The name of the filter to use.
Name of content filter to use. Must be one of the built-in filter names or previously registered with com.rti.dds.domain.DomainParticipant.register_contentfilter on the same com.rti.dds.domain.DomainParticipant.
Built-in filter names are com.rti.dds.domain.DomainParticipant.SQLFILTER_NAME and com.rti.dds.domain.DomainParticipant.STRINGMATCHFILTER_NAME.

String filter_expression = null |
The filter expression.
The expression to filter samples in the DataWriters. It follows the format described in Queries and Filters Syntax.
