WaveTemplateConfigurationModifier Methods

• onConfigurationRetrieval. Runs before the wizard starts. This method is for standard apps only. If the org lacks required data or settings, you can customize the wizard (variables) based on the org data check or disable app creation. Requires WaveTemplateInfo:
  onConfigurationRetrieval(wavetemplate.WaveTemplateInfo waveTemplate)

• beforeAppCreate. Runs after completion of the wizard for standard apps or on app creation for embedded apps. Use this method to avoid errors during app creation as the result of invalid user selections or org settings. Requires WaveTemplateInfo and Answers:
  beforeAppCreate(wavetemplate.WaveTemplateInfo template, wavetemplate.Answers answers)

• beforeAppUpdate. Runs before app updates based on new version of the template for standard and embedded apps. Use this method to validate that org data is compatible with new version. Requires WaveTemplateInfo, Answers, and the previous app version:
  beforeAppUpdate(wavetemplate.WaveTemplateInfo template, String previousAppVersion, wavetemplate.Answers answers)

The methods are optional and all of them can be overridden.
