# Aggregator Function
This module provides an aggregation function that can be reused and composed in other applications.
## Beans for injection
You can import the `AggregatorFunctionConfiguration` in a Spring Boot application and then inject the following bean.
`aggregatorFunction`
You can use `aggregatorFunction` as a qualifier when injecting.
Once injected, you can use the `apply` method of the `Function` to invoke it and get the result.
## Configuration Options

## Tests

## Other usage
