Examples of JavaFunction

org.h2.expression.JavaFunction
This class wraps a user-defined function.
org.keplerproject.luajava.JavaFunction
JavaFunction is a class that can be used to implement a Lua function in Java. JavaFunction is an abstract class, so in order to use it you must extend this class and implement the execute method. This execute method is the method that will be called when you call the function from Lua. To register the JavaFunction in Lua use the method register(String name).
org.lealone.expression.JavaFunction
This class wraps a user-defined function.
xbird.xquery.func.ext.JavaFunction
Function to invoke a Java method.
```
 Ex). declare namespace math = "java:java.lang.Math"; math:log(4) 
```
Limitation:
- The number of arguments is restricted up to 5.
