## Fields

### CREATOR

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final Creator<ImsRegistrationAttributes> CREATOR
```

<br />

<br />

## 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 `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`,
the return value of this method must include the
`https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `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.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: the reference object with which to compare. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getAttributeFlags

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getAttributeFlags ()
```

<br />

<br />

| Returns ||
|---|---|
| `int` | A bit-mask containing attributes associated with the IMS registration. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/telephony/ims/ImsRegistrationAttributes#ATTR_EPDG_OVER_CELL_INTERNET` - `https://developer.android.com/reference/android/telephony/ims/ImsRegistrationAttributes#ATTR_REGISTRATION_TYPE_EMERGENCY` - `https://developer.android.com/reference/android/telephony/ims/ImsRegistrationAttributes#ATTR_VIRTUAL_FOR_ANONYMOUS_EMERGENCY_CALL` |

### getFeatureTags

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Set<String> getFeatureTags ()
```

Gets the Set of feature tags associated with the current IMS registration, if the IMS
service supports supplying this information.


The format of the set of feature tags will be one feature tag key and value per entry and
will potentially contain MMTEL and RCS feature tags, depending the configuration of the IMS
service associated with the registration indications. Each feature tag will contain the
feature tag name and string value (if applicable), even if they have the same feature tag
name. For example, `+g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.oma.cpm.msg,
urn%3Aurn-7%3A3gpp-service.ims.icsi.oma.cpm.session", +g.gsma.callcomposer` will be split
into three feature tag entries:
`{+g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.oma.cpm.msg",
+g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.oma.cpm.session",
+g.gsma.callcomposer}`.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/Set<https://developer.android.com/reference/java/lang/String>` | The Set of feature tags associated with the current IMS registration. This value cannot be `null`. <br /> |

<br />

| Returns ||
|---|---|
| `boolean` | `true` if the ATTR_REGISTRATION_TYPE_EMERGENCY attribute has been set, or `false` if it has not been set. <br /> |

### getFlagVirtualRegistrationForEmergencyCall

Added in [version 36.1](https://developer.android.com/topic/libraries/support-library/revisions)

```
public boolean getFlagVirtualRegistrationForEmergencyCall ()
```

Get the attribute flag ATTR_VIRTUAL_FOR_ANONYMOUS_EMERGENCY_CALL.

<br />

| Returns ||
|---|---|
| `boolean` | `true` if the ATTR_VIRTUAL_FOR_ANONYMOUS_EMERGENCY_CALL attribute has been set, or `false` if it has not been set. <br /> |

### getPcscfAddress

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String getPcscfAddress ()
```

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | The current Proxy-CSCF(P-CSCF) address which UE registers with based on the registration procedure in 3GPP TS 24.229; otherwise, null if the address is not set. <br /> |

### getSipDetails

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public SipDetails getSipDetails ()
```

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/telephony/ims/SipDetails` | The SIP information associated with the IMS registration. This value may be `null`. <br /> |

### getTransportType

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getTransportType ()
```

<br />

<br />

| Returns ||
|---|---|
| `int` | The access network transport type that IMS has been registered over. Value is one of the following: - `https://developer.android.com/reference/android/telephony/AccessNetworkConstants#TRANSPORT_TYPE_WWAN` - `https://developer.android.com/reference/android/telephony/AccessNetworkConstants#TRANSPORT_TYPE_WLAN` |

### 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
`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 `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 `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.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### 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.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the object. <br /> |

### 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.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
