The Packager block creates a packager object to
which payload can be added by subsequent blocks.
With the default parameter settings the buffer size (size of the
serialized package), as well as the sample time of the block is
determined automatically by backward propagation. However, that
values may also be set manually. An example there this
functionality is used is the
TestSerialPackager model. In that model the
parameter sampleTime is explicitly set, since backward
propagation is not possible in that case.
The block is used in several examples, e.g. in,
TestSerialPackager_UDP. The figure below shows an
arrangement in which a Packager object is created and
after that a payload of three Real values and one Integer value is
added, serialized and finally sent using UDP.
