Public methods

convertQuartSecToDecDegrees

Added in API level 17
double convertQuartSecToDecDegrees (int quartSec)

将纬度或经度从0.25秒(如3GPP2 C.S0005-A v6.0标准中定义)转换为十进制度

Parameters
quartSec int: latitude or longitude in 0.25 seconds units
Returns
double latitude or longitude in decimal degrees units
Throws
IllegalArgumentException if value is less than -2592000, greater than 2592000, or is not a number.

equals

Added in API level 5
boolean equals (Object o)

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类的方法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xy ,当且仅当xy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,该方法声明相等对象必须具有相同的哈希代码。

Parameters
o Object: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

fillInNotifierBundle

Added in API level 5
void fillInNotifierBundle (Bundle bundleToFill)

根据服务状态将单元位置数据填入意图通知程序包

Parameters
bundleToFill Bundle: intent notifier Bundle

getBaseStationId

Added in API level 5
int getBaseStationId ()

Returns
int cdma base station identification number, -1 if unknown

getBaseStationLatitude

Added in API level 5
int getBaseStationLatitude ()

纬度是3GPP2 C.S0005-A v6.0中规定的十进制数。 (http://www.3gpp2.org/public_html/specs/C.S0005-A_v6.0.pdf)以0.25秒为单位表示,范围从-1296000到1296000,包括两个值(对应于-90到+90度)。 Integer.MAX_VALUE被认为是无效值。

Returns
int cdma base station latitude in units of 0.25 seconds, Integer.MAX_VALUE if unknown

getBaseStationLongitude

Added in API level 5
int getBaseStationLongitude ()

经度是3GPP2 C.S0005-A v6.0中规定的十进制数。 (http://www.3gpp2.org/public_html/specs/C.S0005-A_v6.0.pdf)以0.25秒为单位表示,范围从-2592000到2592000,包括两个值(对应于-180至+180度)。 Integer.MAX_VALUE被认为是无效值。

Returns
int cdma base station longitude in units of 0.25 seconds, Integer.MAX_VALUE if unknown

getNetworkId

Added in API level 5
int getNetworkId ()

Returns
int cdma network identification number, -1 if unknown

getSystemId

Added in API level 5
int getSystemId ()

Returns
int cdma system identification number, -1 if unknown

hashCode

Added in API level 5
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。)

Returns
int a hash code value for this object.

setCellLocationData

Added in API level 5
void setCellLocationData (int baseStationId, 
                int baseStationLatitude, 
                int baseStationLongitude, 
                int systemId, 
                int networkId)

设置单元格位置数据。

Parameters
baseStationId int
baseStationLatitude int
baseStationLongitude int
systemId int
networkId int

setCellLocationData

Added in API level 5
void setCellLocationData (int baseStationId, 
                int baseStationLatitude, 
                int baseStationLongitude)

设置单元格位置数据。

Parameters
baseStationId int
baseStationLatitude int
baseStationLongitude int

setStateInvalid

Added in API level 5
void setStateInvalid ()

使这个对象无效。 单元格位置数据被设置为无效值。

toString

Added in API level 5
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”此对象的字符串。 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“ @ ”以及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.

Hooray!
