# rama-helpers

This project contains helpful utilities for developing [Rama](https://redplanetlabs.com/docs/~/index.html) modules.

- `ModuleUniqueIdPState`: Generates 64 bit IDs guaranteed to be unique across the whole module.

- `TaskUniqueIdPState`: Generates 32 or 64 bit IDs unique on the task.

- `TopologyScheduler`: Schedules future work for a topology in a robust and fault-tolerant way.

- `KeyToLinkedEntitySetPStateGroup`: Implements map of linked sets data structure. Inner sets can be efficiently queried by membership or by order of insertion.

- `KeyToFixedItemsPStateGroup`: Implements map of fixed lists data structure. Lists of values automatically drop their oldest elements on write when exceeding the configured max size.

- `KeyToUniqueFixedItemsPStateGroup`: Like `KeyToFixedItemsPStateGroup` but also ensures values in inner lists are unique.

- `TaskGlobalField`: Declare an object at the module level to be locally available on every task.

- `TopologyUtils`: Assorted Java functions useful for development and testing.
