/**
* {@link Condition} that will match when none of the nested class conditions match. Can
* be used to create composite conditions, for example:
*
*
* static class OnNeitherJndiNorProperty extends NoneNestedConditions {
*
* OnNeitherJndiNorProperty() {
* super(ConfigurationPhase.PARSE_CONFIGURATION);
* }
*
* @ConditionalOnJndi()
* static class OnJndi {
* }
*
* @ConditionalOnProperty("something")
* static class OnProperty {
* }
*
* }
*
*
* The
* {@link org.springframework.context.annotation.ConfigurationCondition.ConfigurationPhase
* ConfigurationPhase} should be specified according to the conditions that are defined.
* In the example above, all conditions are static and can be evaluated early so
* {@code PARSE_CONFIGURATION} is a right fit.
