Class OSBadBooleanDeserializer

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<Boolean>

org.openstack4j.core.transport.internal.OSBadBooleanDeserializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.NullValueProvider

public class OSBadBooleanDeserializer
extends com.fasterxml.jackson.databind.JsonDeserializer<Boolean>

Openstack API V2 has a few Services which return a 'True' as a boolean value. Jackson typically will not realize that this is equivalent to 'true' and will throw an error. This Deserializer is a workaround to both problems
