Types

The following types are similar to those described in MooseX::Types::Common::Numeric.

"PositiveNum"

"PositiveOrZeroNum"

"PositiveInt"

"PositiveOrZeroInt"

"NegativeNum"

"NegativeOrZeroNum"

"NegativeInt"

"NegativeOrZeroInt"

"SingleDigit"

"SingleDigit" interestingly accepts the numbers -9 to -1; not just 0 to 9.

This module also defines an extra pair of type constraints not found in MooseX::Types::Common::Numeric.

"IntRange[`min, `max]"

Type constraint for an integer between min and max. For example:

  IntRange[1, 10]
    

The maximum can be omitted.

  IntRange[10]   # at least 10
    

The minimum and maximum are inclusive.

"NumRange[`min, `max]"

Type constraint for a number between min and max. For example:

  NumRange[0.1, 10.0]
    

As with IntRange, the maximum can be omitted, and the minimum and maximum are inclusive.

Exclusive ranges can be useful for non-integer values, so additional parameters can be given to make the minimum and maximum exclusive.

  NumRange[0.1, 10.0, 0, 0]  # both inclusive
  NumRange[0.1, 10.0, 0, 1]  # exclusive maximum, so 10.0 is invalid
  NumRange[0.1, 10.0, 1, 0]  # exclusive minimum, so 0.1 is invalid
  NumRange[0.1, 10.0, 1, 1]  # both exclusive
    

Making one of the limits exclusive means that a "<" or ">" operator will be used instead of the usual "<=" or ">=" operators.
