## Fields

### CREATOR

    public static final Creator<RouteSelectionDescriptor> CREATOR

## 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 `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`: This value may be `null`.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### getDataNetworkName

    public List<String> getDataNetworkName ()

DNN stands for Data Network Name and represents an APN as defined in 3GPP TS 23.003. There can be 0 or more DNNs specified in a route selection descriptor.

Returns
`List<String>` | the list of DNN for this route selection descriptor. This value cannot be `null`.

### getPrecedence

    public int getPrecedence ()

Precedence value in the range of 0 to 255. Higher value has lower precedence.

Returns
`int` | the precedence value for this route selection descriptor. Value is between MIN_ROUTE_PRECEDENCE and MAX_ROUTE_PRECEDENCE inclusive

### getSessionType

    public int getSessionType ()

This is used for checking which session type defined in 3GPP TS 23.501 is allowed for the route in a route selection descriptor.

Returns
`int` | the session type for this route selection descriptor. Value is `SESSION_TYPE_IPV4`, `SESSION_TYPE_IPV6`, or `SESSION_TYPE_IPV4V6`

### getSliceInfo

    public List<NetworkSliceInfo> getSliceInfo ()

This is the list of all the slices available in the route selection descriptor as indicated by the network. These are the slices that can be used by the device if this route selection descriptor is used based the traffic (see 3GPP TS 23.501 for details).

Returns
`List<NetworkSliceInfo>` | the list of all the slices available in the route selection descriptor. This value cannot be `null`.

### getSscMode

    public int getSscMode ()

SSC mode stands for Session and Service Continuity mode (which specifies the IP continuity mode) as defined in 3GPP TS 23.501.

Returns
`int` | the SSC mode for this route selection descriptor. Value is `ROUTE_SSC_MODE_1`, `ROUTE_SSC_MODE_2`, or `ROUTE_SSC_MODE_3`

### 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` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Flatten this object in to a Parcel.

Parameters
`dest` | `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
