Camera.Size

public class Camera.Size
extends Object

java.lang.Object
    android.hardware.Camera.Size


该类在API级别21中已被弃用。
我们建议将新的android.hardware.camera2 API用于新应用程序。

图像大小(宽度和高度尺寸)。

摘要(Summary)

Fields

public int height

图片的高度

public int width

图片的宽度

Public constructors

Camera.Size(int w, int h)

设置图片的尺寸。

公共方法(Public methods)

boolean equals(Object obj)

obj与此大小比较。

int hashCode()

返回对象的哈希码值。

继承方法(Inherited methods)

From class java.lang.Object

Fields

height

Added in API level 1
int height

图片的高度

width

Added in API level 1
int width

图片的宽度

Public constructors

Camera.Size

Added in API level 1
Camera.Size (int w, 
                int h)

设置图片的尺寸。

参数(Parameters)
w int: the photo width (pixels)
h int: the photo height (pixels)

公共方法(Public methods)

equals

Added in API level 1
boolean equals (Object obj)

obj与此大小比较。

参数(Parameters)
obj Object: the object to compare this size with.
返回(Returns)
boolean true if the width and height of obj is the same as those of this size. false otherwise.

hashCode

Added in API level 1
int hashCode ()

返回对象的哈希码值。 为了散列表的好处而支持该方法,例如由HashMap提供的HashMap

hashCode的总合同是:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

尽可能合理实用,类Object定义的hashCode方法确实为不同的对象返回不同的整数。 (这通常通过将对象的内部地址转换为整数来实现,但Java TM编程语言不需要此实现技术。)

返回(Returns)
int a hash code value for this object.

Hooray!
