}

Example 14 with AnnotationValue

use of javax.lang.model.element.AnnotationValue in project realm-java by realm.

the class ModuleMetaData method hasCustomClassList.

    }
}

Example 15 with AnnotationValue

use of javax.lang.model.element.AnnotationValue in project auto by google.

the class AnnotationMirrors method getAnnotationValuesWithDefaults.

/**
   * Returns the {@link AnnotationMirror}'s map of {@link AnnotationValue} indexed by
   * {@link ExecutableElement}, supplying default values from the annotation if the
   * annotation property has not been set.  This is equivalent to
   * {@link Elements#getElementValuesWithDefaults(AnnotationMirror)} but can be called
   * statically without an {@link Elements} instance.
