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 and to the keyword void.

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 TypeMirror object, either use a visitor or use the result of the getKind() method. Using instanceof is 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 multiple TypeMirror subinterfaces.

方法概要

限定符和类型	方法	说明
<R,P> R	accept(TypeVisitor<R,P> v, P p)	Applies a visitor to this type.
boolean	equals(Object obj)	Obeys the general contract of Object.equals.
TypeKind	getKind()	Returns the kind of this type.
int	hashCode()	Obeys the general contract of Object.hashCode.
String	toString()	Returns an informative string representation of this type.

方法详细资料

getKind

TypeKind getKind()

Returns the kind of this type.

返回:

the kind of this type

equals

boolean equals(Object obj)

Obeys the general contract of Object.equals. This method does not, however, indicate whether two types represent the same type. Semantic comparisons of type equality should instead use Types.isSameType(TypeMirror, TypeMirror). The results of t1.equals(t2) and Types.isSameType(t1, t2) may differ.

覆盖:

equals 在类中 Object

参数:

obj - the object to be compared with this type

返回:

true if the specified object is equal to this one

Object.hashCode(), HashMap

hashCode

int hashCode()

Obeys the general contract of Object.hashCode.

覆盖:

hashCode 在类中 Object

返回:

a hash code value for this object.

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.

覆盖:

toString 在类中 Object

返回:

a string representation of this type

accept

<R,P> R accept(TypeVisitor<R,P> v,
               P p)

Applies a visitor to this type.

类型参数:

R - the return type of the visitor's methods

P - the type of the additional parameter to the visitor's methods

参数:

v - the visitor operating on this type

p - additional parameter to the visitor

返回:

a visitor-specified result
