Types

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

•

•

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.
