Examples with TypeCompound com.sun.tools.javac.code.Attribute.TypeCompound used on opensource projects

Example 6 with TypeCompound

use of com.sun.tools.javac.code.Attribute.TypeCompound in project checker-framework by typetools.

the class TypeParamElementAnnotationApplier method handleTargeted.

/**
 * @param targeted the list of annotations that were on the lower/upper bounds of the type
 *     parameter
 *     <p>Note: When handling type parameters we NEVER add primary annotations to the type
 *     parameter. Primary annotations are reserved for the use of a type parameter (e.g. @Nullable
 *     T t; )
 *     <p>If an annotation is present on the type parameter itself, it represents the lower-bound
 *     annotation of that type parameter. Any annotation on the extends bound of a type parameter
 *     is placed on that bound.
