== Net::POP3
=== Super Class
Net::Protocol
=== Class Methods
: new( address = 'localhost', port = 110 )
creates a new Net::POP3 object.
This method does not open TCP connection yet.
: start( address = 'localhost', port = 110, account, password )
: start( address = 'localhost', port = 110, account, password ) {|pop| .... }
equals to Net::POP3.new( address, port ).start( account, password )
# typical usage
Net::POP3.start( addr, port, acnt, pass ) do |pop|
pop.each_mail do |m|
any_file.write m.pop
m.delete
end
end
: foreach( address = 'localhost', port = 110, account, password ) {|mail| .... }
starts protocol and iterate for each POPMail object.
This method equals to
Net::POP3.start( address, port, account, password ) do |pop|
pop.each do |m|
yield m
end
end
.
# typical usage
Net::POP3.foreach( addr, nil, acnt, pass ) do |m|
m.pop file
m.delete
end
: delete_all( address = 'localhost', port = 110, account, password )
: delete_all( address = 'localhost', port = 110, account, password ) {|mail| .... }
starts POP3 session and delete all mails.
If block is given, iterates for each POPMail object before delete.
# typical usage
Net::POP3.delete_all( addr, nil, acnt, pass ) do |m|
m.pop file
end
=== Methods
: start( account, password )
: start( account, password ) {|pop| .... }
starts POP3 session.
When called with block, gives a POP3 object to block and
closes the session after block call finish.
: mails
an array of ((URL:#POPMail)).
This array is renewed when session started.
: each_mail {|popmail| .... }
: each {|popmail| .... }
is equals to "pop3.mails.each"
: delete_all
: delete_all {|popmail| .... }
deletes all mails.
If called with block, gives mails to the block before deleting.
# example 1
# pop and delete all mails
n = 1
pop.delete_all do |m|
File.open("inbox/#{n}") {|f| f.write m.pop }
n += 1
end
# example 2
# clear all mails on server
Net::POP3.start( addr, port, acc, pass ) do |pop|
pop.delete_all
end
: reset
reset the session. All "deleted mark" are removed.
== Net::APOP
This class defines no new methods.
Only difference from POP3 is using APOP authentification.
=== Super Class
Net::POP3
== Net::POPMail
A class of mail which exists on POP server.
=== Super Class
Object
=== Methods
: pop( dest = '' )
This method fetches a mail and write to 'dest' using '<<' method.
# usage example
mailarr = []
POP3.start( 'localhost', 110 ) do |pop|
pop.each_mail do |popm|
mailarr.push popm.pop # all() returns 'dest' (this time, string)
# or, you can also
# popm.pop( $stdout ) # write mail to stdout
# maybe you also want to delete mail after popping
popm.delete
end
end
: pop {|str| .... }
If pop() is called with block, it gives the block part strings of a mail.
# usage example
POP3.start( 'localhost', 110 ) do |pop3|
pop3.each_mail do |m|
m.pop do |str|
# do anything
end
end
end
: header
This method fetches only mail header.
: top( lines )
This method fetches mail header and 'lines' lines body.
: delete
: delete!
This method deletes mail.
: size
size of mail(bytes)
: deleted?
true if mail was deleted
