# Rfc822Token

`public class Rfc822Token`
`extends Object` ``

java.lang.Object
↳ | android.text.util.Rfc822Token

This class stores an RFC 822-like name, address, and comment, and provides methods to convert them to quoted strings.

## Summary

### Public constructors
`Rfc822Token(String name, String address, String comment)` Creates a new Rfc822Token with the specified name, address, and comment.

### Public methods
`boolean` | `equals(Object o)` Indicates whether some other object is "equal to" this one.
`String` | `getAddress()` Returns the address part.
`String` | `getComment()` Returns the comment part.
`String` | `getName()` Returns the name part.
`int` | `hashCode()` Returns a hash code value for the object.
`static String` | `quoteComment(String comment)` Returns the comment, with internal backslashes and parentheses preceded by backslashes.
`static String` | `quoteName(String name)` Returns the name, with internal backslashes and quotation marks preceded by backslashes.
`static String` | `quoteNameIfNecessary(String name)` Returns the name, conservatively quoting it if there are any characters that are likely to cause trouble outside of a quoted string, or returning it literally if it seems safe.
`void` | `setAddress(String address)` Changes the address to the specified address.
`void` | `setComment(String comment)` Changes the comment to the specified comment.
`void` | `setName(String name)` Changes the name to the specified name.
`String` | `toString()` Returns the name (with quoting added if necessary), the comment (in parentheses), and the address (in angle brackets).

### 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.

## Public constructors

### Rfc822Token

    public Rfc822Token (String name,
                    String address,
                    String comment)

Creates a new Rfc822Token with the specified name, address, and comment.

Parameters
`name` | `String`: This value may be `null`.
`address` | `String`: This value may be `null`.
`comment` | `String`: This value may be `null`.

## Public methods

### 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.

### getAddress

    public String getAddress ()

Returns the address part.

Returns
`String` | This value may be `null`.

### getComment

    public String getComment ()

Returns the comment part.

Returns
`String` | This value may be `null`.

### getName

    public String getName ()

Returns the name part.

Returns
`String` | This value may be `null`.

### 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.

### quoteComment

    public static String quoteComment (String comment)

Returns the comment, with internal backslashes and parentheses preceded by backslashes. The outer parentheses themselves are not added by this method.

Parameters
`comment` | `String`

Returns
`String` |

### quoteName

    public static String quoteName (String name)

Returns the name, with internal backslashes and quotation marks preceded by backslashes. The outer quote marks themselves are not added by this method.

Parameters
`name` | `String`

Returns
`String` |

### quoteNameIfNecessary

    public static String quoteNameIfNecessary (String name)

Returns the name, conservatively quoting it if there are any characters that are likely to cause trouble outside of a quoted string, or returning it literally if it seems safe.

Parameters
`name` | `String`

Returns
`String` |

### setAddress

    public void setAddress (String address)

Changes the address to the specified address.

Parameters
`address` | `String`: This value may be `null`.

### setComment

    public void setComment (String comment)

Changes the comment to the specified comment.

Parameters
`comment` | `String`: This value may be `null`.

### setName

    public void setName (String name)

Changes the name to the specified name.

Parameters
`name` | `String`: This value may be `null`.

### toString

    public String toString ()

Returns the name (with quoting added if necessary), the comment (in parentheses), and the address (in angle brackets). This should be suitable for inclusion in an RFC 822 address list.

Returns
`String` | a string representation of the object.
