Interface Feature<T extends Feature<T>>

All Known Implementing Classes:

GuavaLibrary, SourceLevel

public interface Feature<T extends Feature<T>>

A feature encapsulates the availability of a type or source level feature that can be used in the source written to a SourceBuilder, such as Java language-level features, or Guava types and methods.

A feature will typically provide a FeatureType constant that can be passed to SourceBuilder#feature(FeatureType) to determine the current status of a feature. For instance, to determine whether the diamond operator is available for use:

code.feature(SOURCE_LEVEL).supportsDiamondOperator()
