Fields
Public methods
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
 instance's marshaled representation. For example, if the object will
 include a file descriptor in the output of writeToParcel(android.os.Parcel, int),
 the return value of this method must include the
 CONTENTS_FILE_DESCRIPTOR bit.
| 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. | 
getHysteresisDb
public int getHysteresisDb ()
Get measurement hysteresis db.
| Returns | |
|---|---|
| int | hysteresis db value | 
getMaximumNumberOfThresholdsAllowed
public static int getMaximumNumberOfThresholdsAllowed ()
Get the maximum number of threshold allowed in each SignalThresholdInfo.
| Returns | |
|---|---|
| int | the maximum number of thresholds allowed | 
getMinimumNumberOfThresholdsAllowed
public static int getMinimumNumberOfThresholdsAllowed ()
Get the minimum number of thresholds allowed in each SignalThresholdInfo.
| Returns | |
|---|---|
| int | the minimum number of thresholds allowed | 
getRadioAccessNetworkType
public int getRadioAccessNetworkType ()
Get the radio access network type.
getSignalMeasurementType
public int getSignalMeasurementType ()
Get the signal measurement type.
| Returns | |
|---|---|
| int | the SignalMeasurementType value
 Value is SIGNAL_MEASUREMENT_TYPE_UNKNOWN,SIGNAL_MEASUREMENT_TYPE_RSSI,SIGNAL_MEASUREMENT_TYPE_RSCP,SIGNAL_MEASUREMENT_TYPE_RSRP,SIGNAL_MEASUREMENT_TYPE_RSRQ,SIGNAL_MEASUREMENT_TYPE_RSSNR,SIGNAL_MEASUREMENT_TYPE_SSRSRP,SIGNAL_MEASUREMENT_TYPE_SSRSRQ,SIGNAL_MEASUREMENT_TYPE_SSSINR, orSIGNAL_MEASUREMENT_TYPE_ECNO | 
getThresholds
public int[] getThresholds ()
Get the signal strength thresholds. Signal strength thresholds are a list of integer used for suggesting signal level and signal reporting criteria. The range and unit must reference specific SignalMeasurementType. Please refer to https://source.android.com/devices/tech/connect/signal-strength on how signal strength thresholds are used for signal strength reporting.
| Returns | |
|---|---|
| int[] | array of integer of the signal thresholds
 This value cannot be null. | 
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 | a string representation of the object. | 
writeToParcel
public void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
| out | Parcel: 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 |
