## Public methods ### describeContents Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#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](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)
| ### equals Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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`: This value may be`null`.
| | Returns || |-----------|-------------------------------------------------------------------------------| | `boolean` | `true`if this object is the same as the obj argument;`false`otherwise.

This value cannot be`null`.
| ### getPrecedence Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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[ERROR(/android.telephony.data.RouteSelectionDescriptor#MIN_ROUTE_PRECEDENCE)](https://developer.android.com/)and[ERROR(/android.telephony.data.RouteSelectionDescriptor#MAX_ROUTE_PRECEDENCE)](https://developer.android.com/)inclusive
| ### getSessionType Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/android/telephony/data/RouteSelectionDescriptor#SESSION_TYPE_IPV4),[SESSION_TYPE_IPV6](https://developer.android.com/reference/android/telephony/data/RouteSelectionDescriptor#SESSION_TYPE_IPV6), or[SESSION_TYPE_IPV4V6](https://developer.android.com/reference/android/telephony/data/RouteSelectionDescriptor#SESSION_TYPE_IPV4V6)
| ### getSliceInfo Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public List 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](https://developer.android.com/reference/java/util/List)`<`[NetworkSliceInfo](https://developer.android.com/reference/android/telephony/data/NetworkSliceInfo)`>` | the list of all the slices available in the route selection descriptor. This value cannot be`null`.
| ### getSscMode Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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.

| ### hashCode Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/java/util/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](https://developer.android.com/reference/java/lang/Object#equals(java.lang.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](https://developer.android.com/reference/java/lang/Object#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.

| Returns || |-------|-------------------------------------------| | `int` | a hash code value for this object.
| ### toString Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String toString () ``` Returns a string representation of the object.
| Returns || |--------------------------------------------------------------------|-----------------------------------------------| | [String](https://developer.android.com/reference/java/lang/String) | a string representation of the object.
| ### writeToParcel Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` 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](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE). Value is either`0`or a combination of[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
