Field Detail

address

protected java.lang.String address

personal

protected java.lang.String personal

The personal name.

encodedPersonal

protected java.lang.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(java.lang.String address)
                throws AddressException

Constructor.

Parse the given string and create an InternetAddress.

Parameters:

address - the address in RFC822 format

Throws:

AddressException - if the parse failed

InternetAddress

public InternetAddress(java.lang.String address,
                       java.lang.String personal)
                throws java.io.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

InternetAddress

public InternetAddress(java.lang.String address,
                       java.lang.String personal,
                       java.lang.String charset)
                throws java.io.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 charset for the name

Method Detail

getType

public java.lang.String getType()

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

Overrides:

getType in class Address

Tags copied from class: Address

Returns:

address type

InternetAddress

setAddress

public void setAddress(java.lang.String address)

Set the email address.

Parameters:

address - email address

setPersonal

public void setPersonal(java.lang.String name,
                        java.lang.String charset)
                 throws java.io.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 - charset to be used to encode the name as per RFC 2047.

Throws:

java.io.UnsupportedEncodingException - if the charset encoding fails.

See Also:

setPersonal(String)

setPersonal

public void setPersonal(java.lang.String name)
                 throws java.io.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:

java.io.UnsupportedEncodingException - if the charset encoding fails.

See Also:

setPersonal(String name, String charset)

getAddress

public java.lang.String getAddress()

Get the email address.

Returns:

email address

getPersonal

public java.lang.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 convertion fails, the raw data is returned as is.

Returns:

personal name

toString

public java.lang.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

equals

public boolean equals(java.lang.Object a)

The equality operator.

Overrides:

equals in class Address

Tags copied from class: Address

Parameters:

address - Address object

hashCode

public int hashCode()

Compute a hash code for the address.

Overrides:

hashCode in class java.lang.Object

toString

public static java.lang.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 address strings

Throws:

ClassCastException, - if any address object in the given array is not an InternetAddress objects. Note that this is a RuntimeException.

toString

public static java.lang.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. Its 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 address strings

Throws:

ClassCastException, - if any address object in the given array is not an InternetAddress objects. 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(java.lang.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(java.lang.String s,
                                      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
