This calculator calculates the duration, which is the day count and the number of days, months and years between two dates.
Constraints are very useful because they allow your application to have different responses based on dynamic application, data, business environment, or real-time conditions.
For example, you might use a constraint to grant a user access to a resource only during certain hours of the day.
When checking if a value is within an attribute, the constraint must be written as: Several types of attributes are provided that are automatically computed for you (see Declarations).
Once a grant result is determined at runtime by the ASI Authorizer (also called the Authorization and Role Mapping Engine (ARME)) for a particular resource, the rest of the applicable policies, which may contain additional constraints, are ignored.
Therefore, if your business logic requires the evaluation of multiple constraints, you must combine them into a complex constraint using an would be granted access would be determined by which policy the ASI Authorizer evaluates first.
If the goal is to grant access only if both constraints are true, you must combine these policies into one policy using the , that are used to perform regular expression matching on attribute values or string literals.This is typically used for pattern matching on resource names.For example, the following policy provides the matches any string containing the set of characters, such as "Lush" or "Mush".A set of brackets () indicates a one-character regular expression matching any of the characters in the set.For example: matches any sequence of digits but not an empty string.A single-character regular expression followed by a question mark (?
