The sections in this topic describe how to develop your own StreamBase custom functions. StreamBase includes dozens of built-in functions, but if you need a particular feature, you can use the StreamBase Java API to create your own functions.
You can call custom Java functions with the calljava() function, or by means of a function alias. To define and use an alias, you must configure the Java function in the pluginFunctions section of an SBEngine configuration file.
