CREATOR

Implement the Parcelable interface
Public methods
describeContents
public int describeContents ()
Implement the Parcelable interface
| Returns | |
|---|---|
| int | a bitmask indicating the set of special object types marshaled
 by this Parcelable object instance.
 Value is either 0orCONTENTS_FILE_DESCRIPTOR | 
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
 The equals method implements an equivalence relation
 on non-null object references:
 
- It is reflexive: for any non-null reference value
     x,x.equals(x)should returntrue.
- It is symmetric: for any non-null reference values
     xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue.
- It is transitive: for any non-null reference values
     x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
- It is consistent: for any non-null reference values
     xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified.
- For any non-null reference value x,x.equals(null)should returnfalse.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
| o | Object: the reference object with which to compare. | 
| Returns | |
|---|---|
| boolean | trueif this object is the same as the obj
          argument;falseotherwise. | 
getAsuLevel
public int getAsuLevel ()
Get the 1xRTT Level in (Android) ASU. There is no standard definition of ASU for CDMA; however, Android defines it as the the lesser of the following two results (for 1xRTT):
| RSSI Range (dBm) | ASU Value | 
|---|---|
| -75.. | 16 | 
| -82..-76 | 8 | 
| -90..-83 | 4 | 
| -95..-91 | 2 | 
| -100..-96 | 1 | 
| ..-101 | 99 | 
| Ec/Io Range (dB) | ASU Value | 
|---|---|
| -90.. | 16 | 
| -100..-91 | 8 | 
| -115..-101 | 4 | 
| -130..-116 | 2 | 
| --150..-131 | 1 | 
| ..-151 | 99 | 
| Returns | |
|---|---|
| int | 1xRTT Level in Android ASU {1,2,4,8,16,99} | 
getCdmaDbm
public int getCdmaDbm ()
Get the CDMA RSSI value in dBm
| Returns | |
|---|---|
| int | |
getCdmaEcio
public int getCdmaEcio ()
Get the CDMA Ec/Io value in dB*10
| Returns | |
|---|---|
| int | |
getDbm
public int getDbm ()
Get the signal strength as dBm
| Returns | |
|---|---|
| int | min(CDMA RSSI, EVDO RSSI) of the measured cell. | 
getEvdoDbm
public int getEvdoDbm ()
Get the EVDO RSSI value in dBm
| Returns | |
|---|---|
| int | |
getEvdoEcio
public int getEvdoEcio ()
Get the EVDO Ec/Io value in dB*10
| Returns | |
|---|---|
| int | |
getEvdoSnr
public int getEvdoSnr ()
Get the signal to noise ratio. Valid values are 0-8. 8 is the highest.
| Returns | |
|---|---|
| int | |
getLevel
public int getLevel ()
Retrieve an abstract level value for the overall signal quality.
| Returns | |
|---|---|
| int | Value is between CellSignalStrength.SIGNAL_STRENGTH_NONE_OR_UNKNOWNandCellSignalStrength.SIGNAL_STRENGTH_GREATinclusive | 
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
 supported for the benefit of hash tables such as those provided by
 HashMap.
 
 The general contract of hashCode is:
 
- Whenever it is invoked on the same object more than once during
     an execution of a Java application, the hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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 equalsmethod, then calling thehashCodemethod 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 equalsmethod, then calling thehashCodemethod 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.
| Returns | |
|---|---|
| int | a hash code value for this object. | 
toString
public String toString ()
Returns a string representation of the object.
| Returns | |
|---|---|
| String | string representation. | 
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Implement the Parcelable interface
| Parameters | |
|---|---|
| dest | Parcel: The Parcel in which the object should be written.
 This value cannot benull. | 
| flags | int: Additional flags about how the object should be written.
 May be 0 orParcelable.PARCELABLE_WRITE_RETURN_VALUE.
 Value is either0or a combination ofParcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
