# AuthenticatorDescription

`public class AuthenticatorDescription`
`extends Object` `implements Parcelable`

java.lang.Object
↳ | android.accounts.AuthenticatorDescription

A `Parcelable` value type that contains information about an account authenticator.

## Summary

### Inherited constants
From interface `android.os.Parcelable`
`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
`public static final Creator<AuthenticatorDescription>` | `CREATOR` Used to create the object from a parcel.
`public final int` | `accountPreferencesId` A resource id for a hierarchy of PreferenceScreen to be added to the settings page for the account.
`public final boolean` | `customTokens` Authenticator handles its own token caching and permission screen
`public final int` | `iconId` A resource id of a icon for the authenticator
`public final int` | `labelId` A resource id of a label for the authenticator that is suitable for displaying
`public final String` | `packageName` The package name that can be used to lookup the resources from above.
`public final int` | `smallIconId` A resource id of a smaller icon for the authenticator
`public final String` | `type` The string that uniquely identifies an authenticator

### Public constructors
`AuthenticatorDescription(String type, String packageName, int labelId, int iconId, int smallIconId, int prefId, boolean customTokens)` A constructor for a full AuthenticatorDescription
`AuthenticatorDescription(String type, String packageName, int labelId, int iconId, int smallIconId, int prefId)`

### Public methods
`int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`boolean` | `equals(Object o)` Compares the type only, suitable for key comparisons.
`int` | `hashCode()` Returns the hashcode of the type only.
`static AuthenticatorDescription` | `newKey(String type)` A factory method for creating an AuthenticatorDescription that can be used as a key to identify the authenticator by its type.
`String` | `toString()` Returns a string representation of the object.
`void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `android.os.Parcelable`
`abstract int` | `describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void` | `writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

## Public constructors

### AuthenticatorDescription

    public AuthenticatorDescription (String type,
                    String packageName,
                    int labelId,
                    int iconId,
                    int smallIconId,
                    int prefId,
                    boolean customTokens)

A constructor for a full AuthenticatorDescription

Parameters
`type` | `String`
`packageName` | `String`
`labelId` | `int`
`iconId` | `int`
`smallIconId` | `int`
`prefId` | `int`
`customTokens` | `boolean`

### AuthenticatorDescription

    public AuthenticatorDescription (String type,
                    String packageName,
                    int labelId,
                    int iconId,

Parameters
`type` | `String`
`packageName` | `String`
`labelId` | `int`
`iconId` | `int`
`smallIconId` | `int`
`prefId` | `int`

## 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)

Compares the type only, suitable for key comparisons.

Parameters
`o` | `Object`: This value may be `null`.

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

### hashCode

    public int hashCode ()

Returns the hashcode of the type only.

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

### newKey

    public static AuthenticatorDescription newKey (String type)

A factory method for creating an AuthenticatorDescription that can be used as a key to identify the authenticator by its type.

Parameters
`type` | `String`

Returns
`AuthenticatorDescription` |

### 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`: 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
