1 like315 views
The document discusses the use of generic programming in Apex and the Tooling API for Salesforce, focusing on the differences between static and dynamic code. It highlights the advantages and disadvantages of dynamic coding and emphasizes the need for developers to understand user-specific dependencies to write effective code. Additionally, it provides information on potential tools and resources for building applications using dynamic Apex and the Tooling API.

- 4. Agenda • Overview of generic code for Apex • Dynamic Code in Salesforce • Tooling API
- 5. Generic Programming in Apex
- 6. What problems are we solving for? • Rigid or fragile code • Poor Reusability • Lots of patches/quick fixes • Duplicate code • Overly complicated data structures • Maps of maps of maps…
- 7. Who are we talking to today? • ISV developers • Don’t know all conditions of customer orgs • Individual app developers • May need to accept input from clients/customers • Any developer accepting user input • Tailor your queries and results based on user conditions
- 8. Different Ways of Writing Code: Static vs. Dynamic Static • Generated at compile time • Hard coded • Doesn’t usually have dependencies • Works well if you know what’s in the org • Most commonly used by developers at a company developing for their own org Dynamic/Generic • Generated at run time • Dependent on user input • May have org-specific dependencies • Works well if you DON’T know what’s in the org • Most commonly used by developers whose code needs to run in customized orgs
- 9. 2 Different Ways of Writing Code
- 10. Tradeoffs Positives • More detailed information • Less chance of an error down the road • Endless possibilities Negatives • More code to write • More code to test • Less readability
- 11. Tools of the Trade
- 12. Several Ways in Salesforce • Custom Settings/Metadata • Dynamic Apex • Dynamic Visualforce • Dynamic SOQL • Limits class • Schema class
- 13. Dynamic Apex
- 16. Dynamic SOQL • Don’t always know what parameters are available in a user’s org • In your org this will work • What if your customer doesn’t have record types defined for Lead?
- 17. Limits Class • Limits.getDMLRows(); • Limits.getDMLStatements(); • Limits.getHeapSize(); • Limits.getQueries(); • Limits.getQueryRows(); • bit.ly/apexlimitsclass (Apex Limits Class)
- 18. Tooling API An API for building…Tools
- 19. Tooling API Highlights • Gather finely grained metadata about Apex classes, triggers, and tests in an org - Classes, triggers, construction of symbol tables - Query for code coverage, logs, SOQL results • Query metadata about setup objects - Business processes, flows, custom items, workflow components • Can be utilized for source control/continuous integration - Metadata containers, deployment details, code file metadata • Can be queried through REST or SOAP • Similar to Metadata API but with a ton of additional functionality Great for building…tools!
- 20. Our Scenario UTILIZE DYNAMIC APEX TO WRITE APEX USING APEX! APEX-CEPTION!!!
- 21. Additional Tooling API Use Cases • Show all objects that can be analyzed /services/data/v37.0/tooling/sobjects/ • Show list of all classes /services/data/v37.0/tooling/apexManifest • Show all metadata about a class /services/data/v37.0/tooling/sobjects/ApexClass/01po0000004SL5b
- 22. Tools To Be Built • UML Diagram Tool • Symbol Table Visualizer • Automated Testing Tools • Tools to identify unused code • Customize managed packages based on org’s config • Use your imagination!
- 23. Summary Next Steps from Here
- 24. Summary and Next Steps • Be thinking about the right type of code for the app you’re building • Write dynamic code • Gather granular details to build any app • Get out there and build!
