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).

Public methods

equals

Added in API level 1
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: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

getAddress

Added in API level 1
String getAddress ()

Returns the address part.

Returns
String

getComment

Added in API level 1
String getComment ()

Returns the comment part.

Returns
String

getName

Added in API level 1
String getName ()

Returns the name part.

Returns
String

hashCode

Added in API level 1
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 JavaTM programming language.)

Returns
int a hash code value for this object.

quoteComment

Added in API level 1
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

Added in API level 1
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

Added in API level 1
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

Added in API level 1
void setAddress (String address)

Changes the address to the specified address.

Parameters
address String

setComment

Added in API level 1
void setComment (String comment)

Changes the comment to the specified comment.

Parameters
comment String

setName

Added in API level 1
void setName (String name)

Changes the name to the specified name.

Parameters
name String

toString

Added in API level 1
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.
