Apex Design Patterns
關於本電子書
If you are a competent developer with working knowledge of Apex, and now want to deep dive into the world of Apex design patterns to optimize the application performance, then this book is for you. Prior knowledge of Salesforce and Force.com platform is recommended.
What You Will LearnApply OOPs principal in Apex to design a robust and efficient solution to address various facets to a business problemGet to grips with the benefits and applicability of using different design patterns in ApexSolve problems while instantiating, structuring and giving dynamic behavior to Apex classesUnderstand the implementation of creational, structural, behavioral, concurrency and anti-patterns in your applicationFollow the Apex best practices to resolve governor limit issuesGet clued up about the Inheritance, abstract classes, polymorphism in Apex to deal with the object mechanismMaster various design patterns and determine the best out of themExplore the anti patterns that could not be applied to Apex and their appropriate solutionsIn DetailApex is an on-demand programming language providing a complete set of features for building business applications – including data models and objects to manage data. Apex being a proprietor programming language from Salesforce to be worked with multi tenant environment is a lot different than traditional OOPs languages like Java and C#. It acts as a workflow engine for managing collaboration of the data between users, a user interface model to handle forms and other interactions, and a SOAP API for programmatic access and integration.
Apex Design Patterns gives you an insight to several problematic situations that can arise while developing on Force.com platform and the usage of Design patterns to solve them. Packed with real life examples, it gives you a walkthrough from learning design patterns that Apex can offer us, to implementing the appropriate ones in your own application. Furthermore, we learn about the creational patterns that deal with object creation mechanism and structural patterns that helps to identify the relationship between entities. Also, the behavioural and concurrency patterns are put forward explaining the communication between objects and multi-threaded programming paradigm respectively. We later on, deal with the issues regarding structuring of classes, instantiating or how to give a dynamic behaviour at a runtime, with the help of anti-patterns. We learn the basic OOPs principal in polymorphic and modular way to enhance its capability. Also, best practices of writing Apex code are explained to differentiate between the implementation of appropriate patterns. This book will also explain some unique patterns that could be applied to get around governor limits.
By the end of this book, you will be a maestro in developing your applications on Force.com for Salesforce
Style and approachThis book is a step-by-step guide, complete with well-tested programs and real world situations to solve your common occurring problems in Apex design by using the anti-patterns. It gets crackling from exploring every appropriate solution to comparing the best one as per OOps principal.
