ULongRange

The ULongRange dictionary is used to define a range of permitted integer values for a property, with either or both a maximum and minimum value specified. The ConstrainULongRange dictionary is based on this, augmenting it to support exact and ideal values as well.

Properties

max
A numeric value in the range of signed 32-bit integers, specifying the largest permissible value of the property it describes.
min
A numeric value in the range of signed 32-bit integers, specifying the smallest permissible value of the property it describes.

The specified min and/or and max values are required. If no match can be found that is within the given range, an error will occur.
