Instance Method Details

#currentValue(memo) ⇒ Boolean, Hash

Update ‘memo’ key ‘parameterName’ with current ‘validValue’

Parameters:

  • memo (Hash) —

    hash where current ‘validValue’ gets updated

Returns:

  • (Boolean, Hash) —

    true when valid value found, updated ‘memo’

def currentValue( memo )
  currentValue = validValue( validIndex )
  memo[parameterName] = currentValue
  return !currentValue.nil?, memo
end

#nextValue ⇒ Boolean

Advance ‘@validIndex’ to point to next valid entry in ‘@validValue’ -set.

Returns:

  • (Boolean) —

    true is not wrapped around

def nextValue

  self.validIndex= validIndex + 1

    # loop until next valid value found (or wrapped around)
    if validIndex >= validValueCount
      # Wrapped around
      self.validIndex= 0
      return false
    end

    # not wrapped around
    return true

end

#validValue(indx) ⇒ String

Returns element in position ‘indx’ of ‘validValues’.

Returns:

  • (String) —

    element in position ‘indx’ of ‘validValues’

# File 'lib/sbuilder/extension_loader_step_generator.rb', line 154

def validValue( indx )
  validValues[indx]
end

#validValueCount ⇒ Integer

validation

Returns:

  • (Integer) —

    number of domain elements passed ‘action’

def validValueCount
  validValues.length
end

#validValues ⇒ String:Array|Hash:Array

Return (cached ) set of valid values. For non isArray generator return ‘validValuesSet’, else (i.e. isArray = true ) return powerset( validValuesSet )

Returns:

  • (String:Array|Hash:Array) —

    valid_values set for parameter
