from() click to toggle source

Returns the lower bound of the numeric range or `nil` if no lower bound is set. @return [Float,Integer]

   # File lib/puppet/pops/types/p_timespan_type.rb
24 def from
25   @from == -Float::INFINITY ? nil : @from

intersect?(o) click to toggle source

Checks if this numeric range intersects with another

@param o [PNumericType] the range to compare with @return [Boolean] `true` if this range intersects with the other range @api public

   # File lib/puppet/pops/types/p_timespan_type.rb

20 end

merge(o) click to toggle source

Concatenates this range with another range provided that the ranges intersect or are adjacent. When that's not the case, this method will return `nil`

@param o [PAbstractTimeDataType] the range to concatenate with this range @return [PAbstractTimeDataType,nil] the concatenated range or `nil` when the ranges were apart @api public

numeric_from() click to toggle source

Same as from but will return `-Float::Infinity` instead of `nil` if no lower bound is set. @return [Float,Integer]

42 def numeric_to
43   @to
