About Constraints, Conditions, Limits, Parameters, Solutions
In programming languages and environments, the components, rules and dynamics of how to encode and solve problems, mean that constraints or limits are required and have to specified. Satisfying conditions like these are used for optimization, ensuring errors or exceptions, do not occur for example. The action(s) and/or entities encapsulating imposing conditions that variables and/or processes must satisfy and their solutions or parameters.
How and when are these 'constraints' best used:
These are and can be used when and for designing an application, a development utility and enabler, even if it determines set boundaries and rules, limits. These are restrictions, limits, checks and control, mandating type implementation for example, in that sense being programming essentials.
In calls, methods and interfaces it is used effectively for type requirements and implementation details. Boundaries, parameters and conditions restricting arguments and operating/operation details.
Requirements for a particular interface can be inherited or specified, an accessible parameter-less constructor (of reference or value type). Combinations are allowed and at most one specification class needs to form part of it, for proper operation and implementation. Base-class, generics, constructor, interface, used for debugging, detection of incompatibilities, setting limits or type requirements, it is a form or rule or restriction placed on action and operation.
Key Exam Points
- Use it for programming development and environments, C# and VB
- review the Relevant chapters and spend time on the exam study examples for Constraints and Other Framework Fundamentals, that help you to gain a better understanding in this topic
