  • Method Details

    • accept

      public <R, P> R accept(AnnotatedTypeVisitor<R,P> v, P p)
      Description copied from class: AnnotatedTypeMirror
      Applies a visitor to this type.
      Specified by:
      accept in class AnnotatedTypeMirror
      Type Parameters:
      R - the return type of the visitor's methods
      P - the type of the additional parameter to the visitor's methods
      Parameters:
      v - the visitor operating on this type
      p - additional parameter to the visitor
      Returns:
      a visitor-specified result

    • getUnderlyingType

      public NullType getUnderlyingType()
      Description copied from class: AnnotatedTypeMirror
      Returns the underlying unannotated Java type, which this wraps.
      Overrides:
      getUnderlyingType in class AnnotatedTypeMirror
      Returns:
      the underlying type

    • deepCopy

      public AnnotatedTypeMirror.AnnotatedNullType deepCopy(boolean copyAnnotations)
      Description copied from class: AnnotatedTypeMirror
      Returns a deep copy of this type. A deep copy implies that each component type is copied recursively and the returned type refers to those copies in its component locations.

      Note: deepCopy provides two important properties in the returned copy:

      1. Structure preservation -- The exact structure of the original AnnotatedTypeMirror is preserved in the copy including all component types.
      2. Annotation preservation -- All of the annotations from the original AnnotatedTypeMirror and its components have been copied to the new type.
      If copyAnnotations is set to false, the second property, Annotation preservation, is removed. This is useful for cases in which the user may want to copy the structure of a type exactly but NOT its annotations.
      Specified by:
      deepCopy in class AnnotatedTypeMirror
      Returns:
      a deep copy

    • deepCopy

      public AnnotatedTypeMirror.AnnotatedNullType deepCopy()
      Description copied from class: AnnotatedTypeMirror
      Returns a deep copy of this type with annotations.

      Each subclass implements this method with the subclass return type. The method body must always be a call to deepCopy(true).

      Specified by:
      deepCopy in interface org.plumelib.util.DeepCopyable<AnnotatedTypeMirror>
      Specified by:
      deepCopy in class AnnotatedTypeMirror
      Returns:
      a deep copy of this type with annotations

    • shallowCopy

      public AnnotatedTypeMirror.AnnotatedNullType shallowCopy(boolean copyAnnotations)
      Description copied from class: AnnotatedTypeMirror
      Returns a shallow copy of this type. A shallow copy implies that each component type in the output copy refers to the same object as the object being copied.
      Specified by:
      shallowCopy in class AnnotatedTypeMirror
      Parameters:
      copyAnnotations - whether copy should have annotations, i.e. whether field annotations should be copied.

    • shallowCopy

      public AnnotatedTypeMirror.AnnotatedNullType shallowCopy()
      Description copied from class: AnnotatedTypeMirror
      Returns a shallow copy of this type with annotations.

      Each subclass implements this method with the subclass return type. The method body must always be a call to shallowCopy(true).

      Specified by:
      shallowCopy in class AnnotatedTypeMirror
      Returns:
      a shallow copy of this type with annotations
