Struct Surface

pub struct Surface { /* private fields */ }

处理由屏幕合成器管理的原始缓冲区。 Surface 通常由图像缓冲区的使用者（例如 SurfaceTexture、android.media.MediaRecorder 或 android.renderscript.Allocation）创建或从其创建，并交给某种生产者（例如 OpenGL、MediaPlayer 或 CameraDevice）进行绘制。 注意：Surface 就像与其关联的使用者的弱引用。它本身不会阻止其父级使用者被回收。

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 Surface

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

Formats the value using the given formatter.

impl Deref for Surface

type Target = GlobalRef

The resulting type after dereferencing.

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

Dereferences the value.

impl From<&GlobalRef> for Surface

fn from(obj: &GlobalRef) -> Self

Converts to this type from the input type.

impl Into<GlobalRef> for &Surface

fn into(self) -> GlobalRef

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

impl JObjNew for Surface

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 Surface

fn java_ref(&self) -> GlobalRef

获取java对象引用。

impl JType for Surface

const CLASS: &'static str = "android/view/Surface"

java类的名称。

const OBJECT_SIG: &'static str = "Landroid/view/Surface;"

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 Surface

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 Surface

fn to_string(&self) -> String

Converts the given value to a String.
