validateNumber

public static java.lang.String validateNumber(java.lang.Object value,
                                              java.lang.Number min,
                                              java.lang.Number max,
                                              java.lang.Boolean canBeNull)

validate that a number is within boundaries. Also validate if the number is allowed to be null.

Parameters:

value - the numeric value

min - the minimum value the number must match. If this parameter is null, then the number can have any minimum value.

max - the maximum value the number must match. If this parameter is null, then the number can have any maximum value.

canBeNull - flag indicating if the object can be null. If the flag is null, then the object is allowed to be null.

Returns:

the validation error string. Null if the new value is valid.
