                int quality, 
                int latency,

requiresNetworkConnection boolean
features Set

Public methods

describeContents

Added in API level 21
int describeContents ()

描述此Parcelable实例的封送表示中包含的特殊对象的种类。 例如,如果对象将在writeToParcel(Parcel, int)的输出中包含writeToParcel(Parcel, int) ,则此方法的返回值必须包含CONTENTS_FILE_DESCRIPTOR位。

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

equals

Added in API level 21
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:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values 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.
  • For any non-null reference value x, x.equals(null) should return false.

equals方法Object实现了对象上最可能的等价关系; 即对于任何非空参考值xy ,此方法返回true当且仅当xy引用同一对象( x == y具有值true )。

请注意,无论何时覆盖此方法,通常都必须覆盖 hashCode方法,以维护 hashCode方法的一般合同,该方法声明相等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.

getFeatures

Added in API level 21
Set<String> getFeatures ()

返回给定语音支持的一组功能。 特征可以是框架定义的,例如KEY_FEATURE_NETWORK_TIMEOUT_MS或特定引擎。 引擎特定的键必须以其预期的引擎名称作为前缀。 这些键可以用作参数speak(String, int, java.util.HashMap)synthesizeToFile(String, java.util.HashMap, String) 特征值是字符串,其值必须符合其文档中描述的限制。

Returns
Set<String> Set instance. May return null on error.

getLatency

Added in API level 21
int getLatency ()

Returns
int The voice's latency (lower is better)

也可以看看:

getLocale

Added in API level 21
Locale getLocale ()

Returns
Locale The voice's locale

getName

Added in API level 21
String getName ()

Returns
String Unique voice name.

getQuality

Added in API level 21
int getQuality ()

Returns
int The voice's quality (higher is better)

也可以看看:

hashCode

Added in API level 21
int hashCode ()

返回对象的哈希码值。 为了散列表的好处而支持此方法,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,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。)

Returns
int a hash code value for this object.

isNetworkConnectionRequired

Added in API level 21
boolean isNetworkConnectionRequired ()

Returns
boolean Does the Voice require a network connection to work.

toString

Added in API level 21
String toString ()

返回对象的字符串表示形式。 通常, toString方法会返回一个“文本表示”该对象的字符串。 结果应该是一个简洁但内容丰富的表述,对于一个人来说很容易阅读。 建议所有子类重写此方法。

ObjecttoString方法返回一个字符串,其中包含对象为实例的类的名称,符号字符“ @ ”和对象的哈希代码的无符号十六进制表示形式。 换句话说,这个方法返回一个字符串,其值等于:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

Added in API level 21
void writeToParcel (Parcel dest, 
                int flags)

将此对象平铺到一个包裹中。

Parameters
dest Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.

Hooray!
