## Fields

### CREATOR

    public static final Creator<CellSignalStrengthLte> 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 `0` or `CONTENTS_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 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`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

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

    public int getAsuLevel ()

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

`int` | the CQI if available or `UNAVAILABLE` if unavailable. Value is between 0 and 15 inclusive

### getCqiTableIndex

    public int getCqiTableIndex ()

Get table index for channel quality indicator Reference: 3GPP TS 136.213 section 7.2.3.

Returns
`int` | the CQI table index if available or `UNAVAILABLE` if unavailable. Value is between 1 and 6 inclusive

### getRssi

    public int getRssi ()

Get Received Signal Strength Indication (RSSI) in dBm The value range is [-113, -51] inclusively or `CellInfo#UNAVAILABLE` if unavailable. Reference: TS 27.007 8.5 Signal quality +CSQ

Returns
`int` | the RSSI if available or `CellInfo#UNAVAILABLE` if unavailable.

### getRssnr

    public int getRssnr ()

Get reference signal signal-to-noise ratio

Returns
`int` | the RSSNR if available or `UNAVAILABLE` if unavailable.

### getTimingAdvance

    public int getTimingAdvance ()

Get the timing advance value for LTE, as a value in range of 0..1282. `UNAVAILABLE` is reported when there is no active RRC connection. Refer to 3GPP 36.213 Sec 4.2.3

Returns
`int` | the LTE timing advance if available or `UNAVAILABLE` if unavailable.

### 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 `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.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

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.
`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
