Class VirtualizationMappings

java.lang.Object

com.cloudera.director.aws.ec2.VirtualizationMappings

All Implemented Interfaces:

com.google.common.base.Function<String,List<String>>

public class VirtualizationMappings
extends Object
implements com.google.common.base.Function<String,List<String>>

Maps a virtualization type to the instance types that support it. EC2 does not provide a means through the API to discover mappings. This class looks up mappings using a built-in list and an override list that the user can easily modify.
