Tdscdma signal strength related information. This class provides signal strength and signal quality information for the TD-SCDMA air interface. For more information see 3gpp 25.225.

Summary

Inherited constants

int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields

CREATOR

Added in API level 29
public static final Creator<CellSignalStrengthTdscdma> CREATOR

Implement the Parcelable interface

Public methods

describeContents

Added in API level 29
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 0 or CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 29
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.

getAsuLevel

Added in API level 29
public int getAsuLevel ()

Get the RSCP in ASU. Asu is calculated based on 3GPP RSRP. Refer to 3GPP 27.007 (Ver 10.3.0) Sec 8.69

Returns
int RSCP in ASU 0..96, 255, or UNAVAILABLE.

getDbm

Added in API level 29
public int getDbm ()

Get the RSCP as dBm value -120..-24dBm or UNAVAILABLE.

Returns
int

getLevel

Added in API level 29
public int getLevel ()

Retrieve an abstract level value for the overall signal quality.

Returns
int Value is between 0 and 4 inclusive

getRscp

Added in API level 29
public int getRscp ()

Get the RSCP as dBm value -120..-24dBm or UNAVAILABLE.

Returns
int

hashCode

Added in API level 29
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 29
public String toString ()

Returns a string representation of the object.

Returns
String string representation.

writeToParcel

Added in API level 29
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 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
