(Ruby) Transition from Imap.FetchSequenceHeaders to Imap.FetchRange

Provides instructions for replacing deprecated FetchSequenceHeaders method calls with FetchRange.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

imap = Chilkat::CkImap.new()

# ...
# ...

startSeqNum = 1
count = 5

# ------------------------------------------------------------------------
# The FetchSequenceHeaders method is deprecated:

# bundleObj is a CkEmailBundle
bundleObj = imap.FetchSequenceHeaders(startSeqNum,count)
if (imap.get_LastMethodSuccess() == false)
    print imap.lastErrorText() + "\n";
    exit
end

# ...
# ...

# ------------------------------------------------------------------------
# Do the equivalent using FetchRange.
# Your application creates a new, empty EmailBundle object which is passed 
# in the last argument and filled upon success.

headersOnly = true

bundleOut = Chilkat::CkEmailBundle.new()
success = imap.FetchRange(headersOnly,startSeqNum,count,bundleOut)
if (success == false)
    print imap.lastErrorText() + "\n";
    exit
end
