Field Detail

### address

    protected String address

### personal

    protected String personal

  The personal name.

### encodedPersonal

    protected String encodedPersonal

  The RFC 2047 encoded version of the personal name.

  This field and the `personal` field track each other, so if a subclass sets one of these fields directly, it should set the other to `null`, so that it is suitably recomputed.

Constructor Detail

### InternetAddress

    public InternetAddress()

  Default constructor.

### InternetAddress

    public InternetAddress(String address)
                    throws AddressException

  Constructor.

  Parse the given string and create an InternetAddress. See the `parse` method for details of the parsing. The address is parsed using "strict" parsing. This constructor does not perform the additional syntax checks that the `InternetAddress(String address, boolean strict)` constructor does when `strict` is `true`. This constructor is equivalent to `InternetAddress(address, false)`.

  Parameters:
    `address` - the address in RFC822 format
  Throws:
    `AddressException` - if the parse failed

### InternetAddress

    public InternetAddress(String address,
                           boolean strict)
                    throws AddressException

  Parse the given string and create an InternetAddress. If `strict` is false, the detailed syntax of the address isn't checked.

  Parameters:
    `address` - the address in RFC822 format
    `strict` - enforce RFC822 syntax
  Throws:
    `AddressException` - if the parse failed
  Since:
    JavaMail 1.3

### InternetAddress

    public InternetAddress(String address,
                           String personal)
                    throws UnsupportedEncodingException

  Construct an InternetAddress given the address and personal name. The address is assumed to be a syntactically valid RFC822 address.

  Parameters:
    `address` - the address in RFC822 format
    `personal` - the personal name
  Throws:
    `UnsupportedEncodingException`

### InternetAddress

    public InternetAddress(String address,
                           String personal,
                           String charset)
                    throws UnsupportedEncodingException

  Construct an InternetAddress given the address and personal name. The address is assumed to be a syntactically valid RFC822 address.

  Parameters:
    `address` - the address in RFC822 format
    `personal` - the personal name
    `charset` - the MIME charset for the name
  Throws:
    `UnsupportedEncodingException`

Method Detail

### clone

    public Object clone()

  Return a copy of this InternetAddress object.

  Overrides:
    `clone` in class `Object`
  Since:
    JavaMail 1.2

### getType

    public String getType()

  Return the type of this address. The type of an InternetAddress is "rfc822".

  Specified by:
    `getType` in class `Address`
  Returns:
    address type
  See Also:
    `InternetAddress`

### setAddress

    public void setAddress(String address)

  Set the email address.

  Parameters:
    `address` - email address

### setPersonal

    public void setPersonal(String name,
                            String charset)
                     throws UnsupportedEncodingException

  Set the personal name. If the name contains non US-ASCII characters, then the name will be encoded using the specified charset as per RFC 2047. If the name contains only US-ASCII characters, no encoding is done and the name is used as is.

  Parameters:
    `name` - personal name
    `charset` - MIME charset to be used to encode the name as per RFC 2047
  Throws:
    `UnsupportedEncodingException` - if the charset encoding fails.
  See Also:
    `setPersonal(String)`

### setPersonal

    public void setPersonal(String name)
                     throws UnsupportedEncodingException

  Set the personal name. If the name contains non US-ASCII characters, then the name will be encoded using the platform's default charset. If the name contains only US-ASCII characters, no encoding is done and the name is used as is.

  Parameters:
    `name` - personal name
  Throws:
    `UnsupportedEncodingException` - if the charset encoding fails.
  See Also:
    `setPersonal(String name, String charset)`

### getAddress

    public String getAddress()

  Get the email address.

  Returns:
    email address

### getPersonal

    public String getPersonal()

  Get the personal name. If the name is encoded as per RFC 2047, it is decoded and converted into Unicode. If the decoding or conversion fails, the raw data is returned as is.

  Returns:
    personal name

### toString

    public String toString()

  Convert this address into a RFC 822 / RFC 2047 encoded address. The resulting string contains only US-ASCII characters, and hence is mail-safe.

  Specified by:
    `toString` in class `Address`
  Returns:
    possibly encoded address string

### toUnicodeString

    public String toUnicodeString()

  Returns a properly formatted address (RFC 822 syntax) of Unicode characters.

  Returns:
    Unicode address string
  Since:
    JavaMail 1.2

### equals

    public boolean equals(Object a)

  The equality operator.

  Specified by:
    `equals` in class `Address`
  Parameters:
    `a` - Address object

### hashCode

    public int hashCode()

  Compute a hash code for the address.

  Overrides:
    `hashCode` in class `Object`

### toString

    public static String toString(Address[] addresses)

  Convert the given array of InternetAddress objects into a comma separated sequence of address strings. The resulting string contains only US-ASCII characters, and hence is mail-safe.

  Parameters:
    `addresses` - array of InternetAddress objects
  Returns:
    comma separated string of addresses
  Throws:
    `ClassCastException,` - if any address object in the given array is not an InternetAddress object. Note that this is a RuntimeException.

### toString

    public static String toString(Address[] addresses,
                                  int used)

  Convert the given array of InternetAddress objects into a comma separated sequence of address strings. The resulting string contains only US-ASCII characters, and hence is mail-safe.

  The 'used' parameter specifies the number of character positions already taken up in the field into which the resulting address sequence string is to be inserted. It is used to determine the line-break positions in the resulting address sequence string.

  Parameters:
    `addresses` - array of InternetAddress objects
    `used` - number of character positions already used, in the field into which the address string is to be inserted.
  Returns:
    comma separated string of addresses
  Throws:
    `ClassCastException,` - if any address object in the given array is not an InternetAddress object. Note that this is a RuntimeException.

### getLocalAddress

    public static InternetAddress getLocalAddress(Session session)

  Return an InternetAddress object representing the current user. The entire email address may be specified in the "mail.from" property. If not set, the "mail.user" and "mail.host" properties are tried. If those are not set, the "user.name" property and `InetAddress.getLocalHost` method are tried. Security exceptions that may occur while accessing this information are ignored. If it is not possible to determine an email address, null is returned.

  Parameters:
    `session` - Session object used for property lookup
  Returns:
    current user's email address

### parse

    public static InternetAddress[] parse(String addresslist)
                                   throws AddressException

  Parse the given comma separated sequence of addresses into InternetAddress objects. Addresses must follow RFC822 syntax.

  Parameters:
    `addresslist` - comma separated address strings
  Returns:
    array of InternetAddress objects
  Throws:
    `AddressException` - if the parse failed

### parse

    public static InternetAddress[] parse(String addresslist,
                                          boolean strict)
                                   throws AddressException

  Parse the given sequence of addresses into InternetAddress objects. If `strict` is false, simple email addresses separated by spaces are also allowed. If `strict` is true, many (but not all) of the RFC822 syntax rules are enforced. In particular, even if `strict` is true, addresses composed of simple names (with no "@domain" part) are allowed. Such "illegal" addresses are not uncommon in real messages.

  Non-strict parsing is typically used when parsing a list of mail addresses entered by a human. Strict parsing is typically used when parsing address headers in mail messages.

  Parameters:
    `addresslist` - comma separated address strings
    `strict` - enforce RFC822 syntax
  Returns:
    array of InternetAddress objects
  Throws:
    `AddressException` - if the parse failed

### parseHeader

    public static InternetAddress[] parseHeader(String addresslist,
                                                boolean strict)
                                         throws AddressException

  Parse the given sequence of addresses into InternetAddress objects. If `strict` is false, the full syntax rules for individual addresses are not enforced. If `strict` is true, many (but not all) of the RFC822 syntax rules are enforced.

  To better support the range of "invalid" addresses seen in real messages, this method enforces fewer syntax rules than the `parse` method when the strict flag is false and enforces more rules when the strict flag is true. If the strict flag is false and the parse is successful in separating out an email address or addresses, the syntax of the addresses themselves is not checked.

  Parameters:
    `addresslist` - comma separated address strings
    `strict` - enforce RFC822 syntax
  Returns:
    array of InternetAddress objects
  Throws:
    `AddressException` - if the parse failed
  Since:
    JavaMail 1.3

### validate

    public void validate()
                  throws AddressException

  Validate that this address conforms to the syntax rules of RFC 822. The current implementation checks many, but not all, syntax rules. Note that even though the syntax of the address may be correct, there's no guarantee that a mailbox of that name exists.

  Throws:
    `AddressException` - if the address isn't valid.
  Since:
    JavaMail 1.3

### isGroup

    public boolean isGroup()

  Indicates whether this address is an RFC 822 group address. Note that a group address is different than the mailing list addresses supported by most mail servers. Group addresses are rarely used; see RFC 822 for details.

  Returns:
    true if this address represents a group
  Since:
    JavaMail 1.3

### getGroup

    public InternetAddress[] getGroup(boolean strict)
                               throws AddressException

  Return the members of a group address. A group may have zero, one, or more members. If this address is not a group, null is returned. The `strict` parameter controls whether the group list is parsed using strict RFC 822 rules or not. The parsing is done using the `parseHeader` method.

  Returns:
    array of InternetAddress objects, or null
  Throws:
    `AddressException` - if the group list can't be parsed
  Since:
    JavaMail 1.3
