Field Detail

address

protected String address

The address in RFC822 format.

encodedPersonal

protected String encodedPersonal

The personal name in RFC2047 format. Subclasses must ensure that this field is updated if the personal field is updated; alternatively, it can be invalidated by setting to null which will cause it to be recomputed.

personal

protected String personal

The personal name as a Java String. Subclasses must ensure that this field is updated if the encodedPersonal field is updated; alternatively, it can be invalidated by setting to null which will cause it to be recomputed.

Method Detail

clone

public Object clone()

Clone this object.

Overrides:

clone in class Object

Returns:

a copy of this object as created by Object.clone()

getType

public String getType()

Return the type of this address.

Specified by:

getType in class Address

Returns:

the type of this address; always "rfc822"

setAddress

public void setAddress(String address)

Set the address. No validation is performed; validate() can be used to check if it is valid.

Parameters:

address - the address to set

setPersonal

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

Set the personal name. The name is first checked to see if it can be encoded; if this fails then an UnsupportedEncodingException is thrown and no fields are modified.

Parameters:

name - the new personal name

charset - the charset to use; see MimeUtilityencodeWord

Throws:

UnsupportedEncodingException - if the name cannot be encoded

setPersonal

public void setPersonal(String name)
                 throws UnsupportedEncodingException

Set the personal name. The name is first checked to see if it can be encoded using MimeUtility.encodeWord(String); if this fails then an UnsupportedEncodingException is thrown and no fields are modified.

Parameters:

name - the new personal name

Throws:

UnsupportedEncodingException - if the name cannot be encoded

getAddress

public String getAddress()

Return the address.

Returns:

the address

getPersonal

public String getPersonal()

Return the personal name. If the personal field is null, then an attempt is made to decode the encodedPersonal field using MimeUtility.decodeWord(String); if this is sucessful, then the personal field is updated with that value and returned; if there is a problem decoding the text then the raw value from encodedPersonal is returned.

Returns:

the personal name

toString

public String toString()

Return a string representation of this address using only US-ASCII characters.

Specified by:

toString in class Address

Returns:

a string representation of this address

toUnicodeString

public String toUnicodeString()

Return a string representation of this address using Unicode characters.

Returns:

a string representation of this address

equals

public boolean equals(Object o)

Compares two addresses for equality. We define this as true if the other object is an InternetAddress and the two values returned by getAddress() are equal in a case-insensitive comparison.

Specified by:

equals in class Address

Parameters:

o - the other object

Returns:

true if the addresses are the same

hashCode

public int hashCode()

Return the hashCode for this address. We define this to be the hashCode of the address after conversion to lowercase.

Overrides:

hashCode in class Object

Returns:

a hashCode for this address

isGroup

public boolean isGroup()

Return true is this address is an RFC822 group address in the format phrase ":" [#mailbox] ";". We check this by using the presense of a ':' character in the address, and a ';' as the very last character.

Returns:

true is this address represents a group

getGroup

public InternetAddress[] getGroup(boolean strict)
                           throws AddressException

Return the members of a group address. If strict is true and the address does not contain an initial phrase then an AddressException is thrown. Otherwise the phrase is skipped and the remainder of the address is checked to see if it is a group. If it is, the content and strict flag are passed to parseHeader to extract the list of addresses; if it is not a group then null is returned.

Parameters:

strict - whether strict RFC822 checking should be performed

Returns:

an array of InternetAddress objects for the group members, or null if this address is not a group

Throws:

AddressException - if there was a problem parsing the header

getLocalAddress

public static InternetAddress getLocalAddress(Session session)

Return an InternetAddress representing the current user.

If session is not null, we first look for an address specified in its "mail.from" property; if this is not set, we look at its "mail.user" and "mail.host" properties and if both are not null then an address of the form "${mail.user}@${mail.host}" is created. If this fails to give an address, then an attempt is made to create an address by combining the value of the "user.name" System property with the value returned from InetAddress.getLocalHost().getHostName(). Any SecurityException raised accessing the system property or any UnknownHostException raised getting the hostname are ignored.

Finally, an attempt is made to convert the value obtained above to an InternetAddress. If this fails, then null is returned.

Parameters:

session - used to obtain mail properties

Returns:

an InternetAddress for the current user, or null if it cannot be determined

toString

public static String toString(Address[] addresses)

Convert the supplied addresses into a single String of comma-separated text as produced by toString(). No line-break detection is performed.

Parameters:

addresses - the array of addresses to convert

Returns:

a one-line String of comma-separated addresses

toString

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

Convert the supplies addresses into a String of comma-separated text, inserting line-breaks between addresses as needed to restrict the line length to 72 characters. Splits will only be introduced between addresses so an address longer than 71 characters will still be placed on a single line.

Parameters:

addresses - the array of addresses to convert

used - the starting column

Returns:

a String of comma-separated addresses with optional line breaks

parse

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

Parse addresses out of the string with basic checking.

Parameters:

addresses - the addresses to parse

Returns:

an array of InternetAddresses parsed from the string

Throws:

AddressException - if addresses checking fails

parse

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

Parse addresses out of the string.

Parameters:

addresses - the addresses to parse

strict - if true perform detailed checking, if false just perform basic checking

Returns:

an array of InternetAddresses parsed from the string

Throws:

AddressException - if address checking fails

parseHeader

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

Parse addresses out of the string.

Parameters:

addresses - the addresses to parse

strict - if true perform detailed checking, if false perform little checking

Returns:

an array of InternetAddresses parsed from the string

Throws:

AddressException - if address checking fails

validate

public void validate()
              throws AddressException

Validate the address portion of an internet address to ensure validity. Throws an AddressException if any validity problems are encountered.

Throws:

AddressException
