Implementation of Java Connector

In this page, I'll show you how to implement function in java, and use it.

Implementation

This is the implementation of the JavaConnector sample project. By understanding this sample, you can make your function working on the Alinous-Script.

Function implementation

The implementation of the function is below.


package org.example;

import java.util.ArrayList;
import java.util.List;

import org.alinous.jdk.IAlinousFunction;

public class SampleConnector implements IAlinousFunction
{
	/**
	 * Retrun the names of methods to export.
	 */
	public String[] getFunctions() {
		return new String[] {"getHello", "addArray", "addArray2",
				"getMemberAndYou"};
	}
	
	/**
	 * Return the name of this function container.
	 */
	public String getPrefix()
	{
		return "Sample";
	}
	
	public String getHello(String yourName)
	{
		return "Hello " + yourName + ".";
	}
	
	/**
	 * Add new values into array
	 * @param val
	 * @param inArray
	 * @return
	 */
	public String[] addArray(String val, String[] inArray)
	{
		String[] newArray = new String[inArray.length + 1];
		
		for(int i = 0; i < inArray.length; i++){
			newArray[i] = inArray[i];
		}
		
		newArray[inArray.length] = val;
		
		return newArray;
	}
	
	/**
	 * 
	 * @param val
	 * @param inArray
	 * @return
	 */
	public List<String> addArray2(String val, String[] inArray)
	{
		List<String> list = new ArrayList<String>();
		
		for(int i = 0; i < inArray.length; i++){
			list.add(inArray[i]);
		}
		list.add(val);
		
		return list;
	}
	
	/**
	 * 
	 * @param you
	 * @return
	 */
	public SampleBean[] getMemberAndYou(SampleBean you)
	{
		System.out.println(you.getName() + " " + you.getEmail());
		
		List<SampleBean> list = new ArrayList<SampleBean>();
		
		list.add(new SampleBean("TOM", "TOM@tomtest.com", new Integer(40)));
		list.add(new SampleBean("BOB", "BOBBOB@BOBtest.com", new Integer(21)));
		
		list.add(you);
		
		return list.toArray(new SampleBean[list.size()]);
	}

	/**
	 * @param arg0
	 */
	public void setAlinousHome(String arg0) {
		
	}
	
	/**
	 * Show string to insert when the funcName selected in 
	 * the contents assist.
	 */
	@Override
	public String codeAssistString(String funcName) {
		if(funcName.equals("getHello")){
			return "getHello($yourName)";
		}
		if(funcName.equals("addArray")){
			return "addArray($val, @inArray)";
		}
		if(funcName.equals("addArray2")){
			return "addArray2($val, @inArray)";
		}
		if(funcName.equals("getMemberAndYou")){
			return "getMemberAndYou(SampleBean you)";
		}
		
		
		return null;
	}
	
	/**
	 * Get description of the function
	 */
	@Override
	public String descriptionString(String funcName) {
		if(funcName.equals("getHello")){
			return "Return greeting string with your name.";
		}
		if(funcName.equals("addArray")){
			return "Add $val into Array variable @inArray";
		}
		if(funcName.equals("addArray2")){
			return "Add $val into Array variable @inArray";
		}
		if(funcName.equals("getMemberAndYou")){
			return "Return dom variables. Dom variables are correspond to JavaBeans in the Java ccode.";
		}
		
		return null;
	}
	
}

The JavaConnector class implements "IAlinousFunction" interface. This interface is defined at the "alinousjc.jar" in "ALINOUS_HOME/lib/" folder.

In order to make JavaScript funtion, you have to do is next list.

Declare prefix at "public String getPrefix() "
Make functions to call
Export them at "public String[] getFunctions()"
(Optional)Add contents assist information at "public String codeAssistString(String funcName)" and "public String descriptionString(String funcName)"

Funtion's parameters

Parameters of these functions are detected and translated automatically.

You can use

Java primitives objects(String, Int, Long)
Java beans which has Java primirtive Object members
Array of these

as the type of parameter.

Next code is a sample of JavaBean used in the previous code.


package org.example;

public class SampleBean {
	private String name;
	private String email;
	private Integer age;
	
	public SampleBean()
	{
		
	}
	
	public SampleBean(String name, String email, Integer age)
	{
		this.name = name;
		this.email = email;
		this.age = age;
	}
	
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}
