Dynamic Handlers
Dynamic handlers provide ability to incorporate or customize event handlers during runtime without any Devops requirement.
Dynamic handlers are typically facilitated by code or package handlers such as OpenHFTEventHandler, ScriptLoadedEventHandler or JarLoadedEventHandler.
Handler Codes
Handler codes are code blocks which are compiled dynamically at run-time for highly specialized operations which can not be addressed with available event handlers. Handler codes have the following attributes:
Name: Descriptive name of the code
Status: Whether code is currently active or not
Description: Detailed description of what the code does
Domain: Domain of the code which allows deploying multiple codes using a single code handler
Engine: Language / scripting engine to use (e.g. html, java)
Code: Full script or class implementation body
For Java codes, additional attributes are applicable:
Class: Fully qualified class name to be assigned to the code
Dependencies: Extra jar files which shall be retrieved and deployed when compiling the code
Code: Full Java class extending com.rierino.handler.EventHandler, including actionMap mappings to functions
Handler Packages
Handler packages are JAR packages of handler classes which are loaded dynamically at run-time, for use cases that are similar to handler codes. Handler packages have the following attributes:
Name: Descriptive name of the package
Status: Whether package is currently active or not
Description: Detailed description of what the package does
Domain: Domain of the package which allows deploying multiple packages using a single package handler
Files: Jar files included in the package with Urls to download them (see Custom Development for details)
Handlers: Mapping of unique handler ids to fully qualified class names for handlers included in the package
