The TwoQueriesMany exists of 4 runs. During each run the Sender writes 20 samples to DDS.
After that it informs the receiver that the samples were written. The receiver
in turn sets a filter and starts to pull the samples from DDS, using the Getter.
Once the receiver has received all samples, it informs the Sender that the next
run can be started.
Since the getter only receives non-read samples, an extra check is build in. The
receiver also performs a read on a different port in order to check whether the
right samples are available in DDS. This Reader should always receive ALL samples
since the QueryFilter only applies to the Getter.
The following query expression is defined:
( (iteration > %0) AND (iteration < %1) )
The following runs are defined:
1. Sender writes iterations 1-20 to DDS for a certain number of keys,
defined in the deployment plan. The receiver sets the filter and filter
parameters and starts receiving the samples at once, using get_many.
After that it changes the filter parameters and informs the Sender that a
new run can be started.
2. Sender writes iterations 21-40 to DDS for the defined number of keys. After
that it informs the receiver which starts to get the samples from DDS. After
that, the receiver reset the QueryFilter (by setting the expression to an
empty string) and informs the Sender that a new run can be started.
3. Sender writes iterations 41-60 to DDS for the defined number of keys. After
that it informs the receiver which should receive with a get_many all samples
with iterations 1-60 without the ones it read during run 1 and 2.
The receiver then creates a new filter, using the same expression as used during
runs 1 and 2 but with different parameters. Again the receiver informs the
Sender that a new run can be started.
4. Sender writes iterations 61-80 to DDS for the defined number of keys. Again it
informs the receiver about this action. The receiver should only get the samples
according to the query expression and its parameters.
After each get-action, the receiver reads the data from DDS. During this read action,
the receiver should read all samples the Sender has written up to that moment. Since
there's no filter applied to this reader, all sample states should be 'FRESH_INFO'.
