Class AnnotatedTypeMirror

java.lang.Object
  checkers.types.AnnotatedTypeMirror

Direct Known Subclasses:

public abstract class AnnotatedTypeMirror
extends Object

Represents a annotated type in the JSR308 Java programming language. Types include primitive types, declared types (class and interface types), array types, type variables, and the null type. Also represented are wildcard type arguments, the signature and return types of executables, and pseudo-types corresponding to packages and to the keyword void. Types should be compared using the utility methods in AnnotatedTypes. There is no guarantee that any particular type will always be represented by the same object. To implement operations based on the class of an TypeMirror object, either use a visitor or use the result of the getKind() method.

                                             AnnotatedTypeFactory typeFactory)

Creates the appropriate AnnotatedTypeMirror specific wrapper for the provided type

Parameters:

type -

env -

typeFactory -

Returns:

[to document]

directSuperTypes

public List<? extends AnnotatedTypeMirror> directSuperTypes()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

accept

public abstract <R,P> R accept(AnnotatedTypeVisitor<R,P> v,
                               P p)

Applies a visitor to this type.

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

getKind

public TypeKind getKind()

Returns the kind of this type

Returns:

the kind of this type

getUnderlyingType

public TypeMirror getUnderlyingType()

Returns the underlying unannotated Java type wrapped with this

Returns:

the underlying type

getEnclosingType

public AnnotatedTypeMirror getEnclosingType()

Returns the enclosing type, as in the type of A in the type A.B.

Returns:

enclosingType the enclosing type

getAnnotations

public Set<AnnotationMirror> getAnnotations()

Returns the annotations on this type. It does not include annotations in deep types (type arguments, array components, etc).

Returns:

a set of the annotations on this

getAnnotation
