Field Detail

address

protected String address

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.


personal

protected String personal
The personal name.
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

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

equals

public boolean equals(Object a)
The equality operator.

Overrides:
equals in class Address
Parameters:
a

getAddress

public String getAddress()
Get the email address.

Returns:
email address

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.

Parameters:
strict
Returns:
array of InternetAddress objects, or null
Throws:
AddressException - if the group list can't be parsed

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

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

getType

public String getType()
Return the type of this address. The type of an InternetAddress is "rfc822".

Overrides:
getType in class Address

hashCode

public int hashCode()
Compute a hash code for the address.

Overrides:
hashCode in class Object

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

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

setAddress

public void setAddress(String address)
Set the email address.

Parameters:
address - email address

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.

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.

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.

Overrides:
toString in class Address
Returns:
possibly encoded address string

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

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

toUnicodeString

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

Returns:
Unicode address string

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.
