protected boolean	isActive(AnnotatedElement e)	Go up the scope chain (method > class > package > ...) and make sure any OptionalExtensions we encounter are satisified.
protected boolean	isOptional(OptionalExtension annotation)	If the trigger condition is not met, we filter it by not making the extension active, which means extensions could always be non-optional as far as ExtensionFinder.GuiceExtensionAnnotation is concerned.

Method Details

getOrdinal

protected double getOrdinal(OptionalExtension annotation)

Specified by:

getOrdinal in class ExtensionFinder.GuiceExtensionAnnotation<OptionalExtension>

isOptional

protected boolean isOptional(OptionalExtension annotation)

If the trigger condition is not met, we filter it by not making the extension active, which means extensions could always be non-optional as far as ExtensionFinder.GuiceExtensionAnnotation is concerned. But in some situations, the class cannot even be loaded which would make ExtensionFinder.GuiceExtensionAnnotation to fail, so we need to also make it optional.
