Actions Status

A framework for Efficient and Dynamic Collection Selection.

The current version of this framework is a proof-of-concept for our paper at CGO'18.

We will soon be releasing a stable release version for everyones use. We are currentl fixing some rough edges :)

This instructions will get you to build and use CollectionsSwitch in your application.

Prerequisites

To build and run Collections-Bench you need:

Java >= 8
Maven

Installing

This version of the CollectionSwitch has a local dependency on smrt.jar, which is not in any public repository, so first run:

./configure.py ../${PATH_TO}/smrt.jar

You then can simply install the CollectionSwitch by running mvn install in the project.

Using CollectionSwitch Context

The entry point of the CollectionSwitch adaptation is the AllocationContext. To instantiate the context with a default type as JDK ArrayList, you can call the factory method.

static ListAllocationContext ctx = AllocationContextFactory.buildListContext(ListCollectionType.JDK_ARRAYLIST, "myContextName");

We recommend you to only use the context as a static member of a class.

To enable the adaptive behavior, you should allow the collection instantiation to be performed by the context, as follows:

List<T> list = ctx.createList();
