Fields

CREATOR

Added in API level 31

public static final Creator<SignalThresholdInfo> CREATOR

Public methods

describeContents

Added in API level 31

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 0 or CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 31

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 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.

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	true if this object is the same as the obj argument; false otherwise.

getHysteresisDb

Returns
int	the maximum number of thresholds allowed

getMinimumNumberOfThresholdsAllowed

Added in API level 31

public static int getMinimumNumberOfThresholdsAllowed ()

Get the minimum number of thresholds allowed in each SignalThresholdInfo.

Returns
int	the minimum number of thresholds allowed

getRadioAccessNetworkType

Added in API level 31

public int getRadioAccessNetworkType ()

Get the radio access network type.

Returns
int	radio access network type Value is AccessNetworkConstants.AccessNetworkType.UNKNOWN, AccessNetworkConstants.AccessNetworkType.GERAN, AccessNetworkConstants.AccessNetworkType.UTRAN, AccessNetworkConstants.AccessNetworkType.EUTRAN, AccessNetworkConstants.AccessNetworkType.CDMA2000, AccessNetworkConstants.AccessNetworkType.IWLAN, or AccessNetworkConstants.AccessNetworkType.NGRAN

getSignalMeasurementType

Added in API level 31

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, or SIGNAL_MEASUREMENT_TYPE_ECNO

getThresholds

Added in API level 31

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

Added in API level 31

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 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 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 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.

Returns
int	a hash code value for this object.

toString

Added in API level 31

public String toString ()

Returns a string representation of the object.

Returns
String	a string representation of the object.

writeToParcel

Added in API level 31

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out	Parcel: This value cannot be null.
flags	int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
