Constant Summary collapse

RECORDINGS_ELEMENTS =

Represents a recording that is held on the MythTV Backend server we are communicating with.

The keys included here, and the order in which they are specified seem to change between protocol version bumps on the MythTV backend, so this array affects both the initialize() and to_s() methods.

Found inside mythtv/libs/libmythtv/programinfo.cpp in the MythTV subversion repository

#duration ⇒ Object 



35
 
# File 'lib/mythtv/recording.rb', line 35

def duration; self.end - self.start; end

#end ⇒ Object 



34
 
# File 'lib/mythtv/recording.rb', line 34

def end;  Time.at(recendts.to_i); end

#filename ⇒ Object

Strip the filename out from the path returned by the server



52
 
# File 'lib/mythtv/recording.rb', line 52

def filename;  File.basename(URI.parse(pathname).path); end

#filesize ⇒ Object

Convert the lo/hi long representation of the filesize into a string

46
 
# File 'lib/mythtv/recording.rb', line 44

def filesize
  [filesize_lo.to_i, filesize_hi.to_i].pack("ll").unpack("Q").to_s
end

#myth_delimited_recstart ⇒ Object

Cribbed from the Mythweb PHP code. Required for some method calls to the backend



38
 
# File 'lib/mythtv/recording.rb', line 38

def myth_delimited_recstart;  myth_format_time(recstartts, :delimited); end

#myth_nondelimited_recstart ⇒ Object

Formats the start time for use in the copy process, as the latter half of the filename is a non-delimited time string



41
 
# File 'lib/mythtv/recording.rb', line 41

def myth_nondelimited_recstart; myth_format_time(recstartts, :nondelimited);  end

#path ⇒ Object

Fetch the path section of the pathname



49
 
# File 'lib/mythtv/recording.rb', line 49

def path;  URI.parse(pathname).path; end

#start ⇒ Object

Convenience methods to access the start and end times as Time objects, and duration as an Float



33
 
# File 'lib/mythtv/recording.rb', line 33

def start;  Time.at(recstartts.to_i); end

#to_s ⇒ Object

A string representation of a Recording is used when we converse with the MythTV Backend about that recording

def to_s
  RECORDINGS_ELEMENTS.collect { |field| self.send(field.to_s) }.join(MythTV::Backend::FIELD_SEPARATOR) + MythTV::Backend::FIELD_SEPARATOR
