Struct SystemProperties_Handle

pub struct SystemProperties_Handle { /* private fields */ }

预定位属性的句柄。提前查找属性句柄可以实现对单个属性的最佳重复查找。

Implementations

impl SystemProperties_Handle

pub fn get(&self) -> String

返回属性的值

pub fn get_int(&self, def: i32) -> i32

返回int值或def在解析错误上 def 默认值

pub fn get_long(&self, def: i64) -> i64

返回long值或def在解析错误上 def 默认值

pub fn get_boolean(&self, def: bool) -> bool

返回boolean值或def在解析错误上 def 默认值

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 SystemProperties_Handle

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

Formats the value using the given formatter.

impl Deref for SystemProperties_Handle

type Target = GlobalRef

The resulting type after dereferencing.

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

Dereferences the value.

impl From<&GlobalRef> for SystemProperties_Handle

fn from(obj: &GlobalRef) -> Self

Converts to this type from the input type.

impl Into<GlobalRef> for &SystemProperties_Handle

fn into(self) -> GlobalRef

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

impl JObjNew for SystemProperties_Handle

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 SystemProperties_Handle

fn java_ref(&self) -> GlobalRef

获取java对象引用。

impl JType for SystemProperties_Handle

const CLASS: &'static str = "android/os/SystemProperties_Handle"

java类的名称。

const OBJECT_SIG: &'static str = "Landroid/os/SystemProperties_Handle;"

对象的签名描述。

type Error = Error

错误类型。

const DIM: u8 = 0u8

impl PartialEq for SystemProperties_Handle

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 SystemProperties_Handle

fn to_string(&self) -> String

Converts the given value to a String.
