public interface TypeMirror extends AnnotatedConstruct
Represents a type in the 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, modules, and the keywordvoid.Types should be compared using the utility methods in
Types. 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
TypeMirrorobject, either use a visitor or use the result of thegetKind()method. Usinginstanceofis not necessarily a reliable idiom for determining the effective class of an object in this modeling hierarchy since an implementation may choose to have a single object implement multipleTypeMirrorsubinterfaces.

Method Detail
-
getKind
TypeKind getKind()
Returns thekindof this type.- Returns:
- the kind of this type
-
equals
boolean equals(Object obj)
Obeys the general contract ofObject.equals. This method does not, however, indicate whether two types represent the same type. Semantic comparisons of type equality should instead useTypes.isSameType(TypeMirror, TypeMirror). The results oft1.equals(t2)andTypes.isSameType(t1, t2)may differ.- Overrides:
equalsin classObject- Parameters:
obj- the object to be compared with this type- Returns:
trueif the specified object is equal to this one- See Also:
Object.hashCode(),HashMap
-
hashCode
int hashCode()
Obeys the general contract ofObject.hashCode.- Overrides:
hashCodein classObject- Returns:
- a hash code value for this object.
- See Also:
equals(java.lang.Object)
-
toString
String toString()
Returns an informative string representation of this type. If possible, the string should be of a form suitable for representing this type in source code. Any names embedded in the result are qualified if possible.
-
accept
<R,P> R accept(TypeVisitor<R,P> v, P p)
Applies a visitor to this type.- Type Parameters:
R- the return type of the visitor's methodsP- the type of the additional parameter to the visitor's methods- Parameters:
v- the visitor operating on this typep- additional parameter to the visitor- Returns:
- a visitor-specified result
