public static final class Intent.FilterComparison
extends Object
| java.lang.Object | |
| ↳ | android.content.Intent.FilterComparison |
包装类持有一个意图和执行比较在过滤的目的。 该类将其equals()和hashCode()方法实现为包装的Intent上的对filterEquals(Intent) filterEquals（）}和filterHashCode() filterHashCode（）的简单调用。

boolean equals (Object obj)
指示其他某个对象是否“等于”这一个。
equals方法在非空对象引用上实现等价关系：
Android开发手册x, x.equals(x) should return true. x and y, x.equals(y) should return true if and only if y.equals(x) returns true. x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified. x, x.equals(null) should return false. 类equals方法Object实现了对象上最可能的等价关系; 也就是说，对于任何非空参考值x和y ，当且仅当x和y引用同一对象（ x == y的值为true ）时，此方法返回true 。
请注意，无论何时重写此方法，通常都需要重写 hashCode方法，以便维护 hashCode方法的常规协定，该方法声明等同对象必须具有相同的哈希代码。
| Parameters | |
|---|---|
obj |
Object: the reference object with which to compare. |
| Returns | |
|---|---|
boolean |
true if this object is the same as the obj argument; false otherwise. |
Intent getIntent ()
返回FilterComparison表示的Intent。
| Returns | |
|---|---|
Intent |
Returns the Intent held by the FilterComparison. Do not modify! |
int hashCode ()
返回对象的哈希码值。 这种方法支持散列表的好处，例如HashMap提供的HashMap 。
hashCode的总合同是：
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. equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. 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，由类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。）

a hash code value for this object. |
