Class: Scaffolder::Region::Insert

Inherits:
Scaffolder::Region show all
Defined in:
lib/scaffolder/region/insert.rb

Overview

Inserts are used to additional usually smaller sequences to larger sequences. The attributes in the sequence class are used to specify where the host sequence is ‘opened’ and ‘closed’ to add the insert. Either one of these two attributes may be ommitted. Omitting the ‘open’ attribute will cause the insert open position to be calculated based on the close minus the sequence length. The reverse is true if the close position is ommittted.

Instance Method Details

#<=>(other) ⇒ Integer

Inserts are comparable by close position.

Parameters:

Returns:

  • (Integer)

def <=>(other)
  self.close <=> other.close
end

#close ⇒ Integer

End position where insert is added. Default is open position plus the sequence length.

Parameters:

  • (Integer)

Returns:

  • (Integer)

attribute :close,
:default => lambda{|s| s.open  + s.sequence_hook.length - 1 }

#open ⇒ Integer

Open position where insert is added. Default is close position minus the sequence length.

Parameters:

  • (Integer)

Returns:

  • (Integer)

attribute :open,
:default => lambda{|s| s.close - s.sequence_hook.length - 1 }

#position ⇒ Range

Insertion position as a Range

Returns:

  • (Range)

Raises:

  • (CoordinateError) —

    if both the open and close positions are nil.
