Enum values

APPEND

enum val APPEND : ExistingWorkPolicy

If there is existing pending (uncompleted) work with the same unique name, append the newly-specified work as a child of all the leaves of that work sequence. Otherwise, insert the newly-specified work as the start of a new sequence.
Note: When using APPEND with failed or cancelled prerequisites, newly enqueued work will also be marked as failed or cancelled respectively. Use ExistingWorkPolicy#APPEND_OR_REPLACE to create a new chain of work.

APPEND_OR_REPLACE

enum val APPEND_OR_REPLACE : ExistingWorkPolicy

If there is existing pending (uncompleted) work with the same unique name, append the newly-specified work as the child of all the leaves of that work sequence. Otherwise, insert the newly-specified work as the start of a new sequence.
Note: If there are failed or cancelled prerequisites, these prerequisites are dropped and the newly-specified work is the start of a new sequence.

KEEP

enum val KEEP : ExistingWorkPolicy

If there is existing pending (uncompleted) work with the same unique name, do nothing. Otherwise, insert the newly-specified work.

REPLACE

enum val REPLACE : ExistingWorkPolicy

If there is existing pending (uncompleted) work with the same unique name, cancel and delete it. Then, insert the newly-specified work.
