Struct Method

pub struct Method { /* private fields */ }

方法提供有关类或接口上的单个方法的信息和访问权。反射方法可以是类方法或实例方法（包括抽象方法）。当将要调用的实际参数与底层方法的形式参数匹配时，方法允许发生扩展转换，但如果发生缩小转换，则会引发 IllegalArgumentException。

Implementations

impl Method

pub fn get_name(&self) -> String

以字符串形式返回此 Method 对象所表示的方法的名称。

pub fn get_parameter_count(&self) -> i32

返回此对象所代表的可执行文件的形式参数数量（无论是显式声明、隐式声明还是均未声明）。 返回：此对象所代表的可执行文件的形式参数数量

Methods from Deref<Target = Executable>

pub fn get_name(&self) -> String

返回此对象所代表的可执行文件的名称。

pub fn get_parameter_count(&self) -> i32

返回此对象所代表的可执行文件的形式参数数量（无论是显式声明、隐式声明还是均未声明）。 返回：此对象所代表的可执行文件的形式参数数量

Methods from Deref<Target = GlobalRef>

pub fn as_obj(&self) -> &JObject<'static>

Get the object from the global ref

This borrows the ref and prevents it from being dropped as long as the JObject sticks around.

Methods from Deref<Target = JObject<'static>>

pub fn as_raw(&self) -> *mut _jobject

Returns the raw JNI pointer.

Trait Implementations

impl Debug for Method

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for Method

type Target = Executable

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Method

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<&GlobalRef> for Method

fn from(obj: &GlobalRef) -> Self

Converts to this type from the input type.

impl Into<GlobalRef> for &Method

fn into(self) -> GlobalRef

Converts this type into the (usually inferred) input type.

impl JObjNew for Method

type Fields = ()

字段类型

fn _new(this: &GlobalRef, fields: Self::Fields) -> Self

从java对象创建本地对象。 this java对象引用。

fn null() -> Self

where Self: Sized, Self::Fields: Default,

创建空对象。

impl JObjRef for Method

fn java_ref(&self) -> GlobalRef

获取java对象引用。

impl JType for Method

const CLASS: &'static str = "java/lang/reflect/Method"

java类的名称。

const OBJECT_SIG: &'static str = "Ljava/lang/reflect/Method;"

对象的签名描述。

type Error = Error

错误类型。

const DIM: u8 = 0u8

数组维度，0表示不是数组

impl PartialEq for Method

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToString for Method

fn to_string(&self) -> String

Converts the given value to a String.
