# 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.
