public int getCommandVersion()
This version must be incremented, if this command is modified!
Note, that a final
command cannot be modified!!! You can only modify a final command
if this command was newly introduced in the current SNAPSHOT. Never modify a command after it
was released!!!
The version returned by the implementation of this method in MinimumCumulus4jVersion
is the
lowest version of cumulus4j that runs with the current datastore.
In other words: This version here must be set to the current Cumulus4j version, if a lower version of Cumulus4j cannot be used with the datastore structure represented by the current source code, anymore.
This version is composed of the following parts:
For example, the 3rd non-downgradable change to the version 9.08.07-SNAPSHOT would result in the numeric result 90807002 (the serial starts at 0, hence 3rd change = 2). This number is not incremented at the release of 9.08.07! It is only incremented, if the data structure changes in a way that prevents older versions from operating!
