Method Detail

setSaveParameters

public void setSaveParameters(Function<Map<String,String>,rx.Completable> saveParameters)

get

public String get(String key)

Description copied from interface: JobParameters

Return the value associated with the key or null if there is no such parameter

Specified by:

get in interface JobParameters

put

public String put(String key,
                  String value)

Description copied from interface: JobParameters

Associates the value with the key and returns the old value if there previously was a mapping for the key

Specified by:

put in interface JobParameters

remove

public String remove(String key)

Description copied from interface: JobParameters

Removes the value associated with the key or null if there is no such parameter

Specified by:

remove in interface JobParameters

containsKey

public boolean containsKey(String key)

Description copied from interface: JobParameters

Return true if the parameters contain a value for the key

Specified by:

containsKey in interface JobParameters

getMap

public Map<String,String> getMap()

Description copied from interface: JobParameters

Return an immutable map of the parameters. Note that this map is a copy. Any changes made to the parameters through methods like get or put will not be reflected in this map.

Specified by:

getMap in interface JobParameters

save

public rx.Completable save()

Description copied from interface: JobParameters

Asynchronously save the parameters back to Cassandra. For reoccurring jobs any changes to parameters will automatically be persisted when the job finishes and is rescheduled for its next run. This method can be useful for long running jobs that perform a lot of work. It can be used to create checkpoints so that if a job is abruptly stopped and restarted it can resume its work from that checkpoint rather than starting all over.

Specified by:

save in interface JobParameters
