方法详细资料

getTypeParameters

List<? extends TypeParameterElement> getTypeParameters()

Returns the formal type parameters of this executable in declaration order.

指定者:

getTypeParameters 在接口中 Parameterizable

返回:

the formal type parameters, or an empty list if there are none

getReturnType

TypeMirror getReturnType()

Returns the return type of this executable. Returns a NoType with kind VOID if this executable is not a method, or is a method that does not return a value.

返回:

the return type of this executable

getParameters

List<? extends VariableElement> getParameters()

Returns the formal parameters of this executable. They are returned in declaration order.

返回:

the formal parameters, or an empty list if there are none

getReceiverType

TypeMirror getReceiverType()

Returns the receiver type of this executable, or NoType with kind NONE if the executable has no receiver type. An executable which is an instance method, or a constructor of an inner class, has a receiver type derived from the declaring type. An executable which is a static method, or a constructor of a non-inner class, or an initializer (static or instance), has no receiver type.

返回:

the receiver type of this executable

isVarArgs

boolean isVarArgs()

Returns true if this method or constructor accepts a variable number of arguments and returns false otherwise.

返回:

true if this method or constructor accepts a variable number of arguments and false otherwise

isDefault

boolean isDefault()

Returns true if this method is a default method and returns false otherwise.

返回:

true if this method is a default method and false otherwise

从以下版本开始:

1.8

getThrownTypes

List<? extends TypeMirror> getThrownTypes()

Returns the exceptions and other throwables listed in this method or constructor's throws clause in declaration order.

返回:

the exceptions and other throwables listed in the throws clause, or an empty list if there are none

getDefaultValue

AnnotationValue getDefaultValue()

Returns the default value if this executable is an annotation type element. Returns null if this method is not an annotation type element, or if it is an annotation type element with no default value.

返回:

the default value, or null if none

getSimpleName

Name getSimpleName()

Returns the simple name of a constructor, method, or initializer. For a constructor, the name "<init>" is returned, for a static initializer, the name "<clinit>" is returned, and for an anonymous class or instance initializer, an empty name is returned.

指定者:

getSimpleName 在接口中 Element

返回:

the simple name of a constructor, method, or initializer
