compilation-toolbox
===================
This repository is a fork of https://code.google.com/p/compilation-toolbox, meant to include some improvements.
About Compilation Toolbox
==========================
Dynamic code generation is ability to generate Java classes at runtime and loading them and access in the same way as ordinary compiled Java Classes. This could be achieved either by using byte-code generation libraries like Apache BCEL, asm, cglib, javaassist or by using java compilation api (javax.tools). This library uses the latter approach providing comprehensive api to both compiling and loading dynamically generated classes.
Introduction
============
Java runtime source code compiler and loader. It simply compiles a given source code and loads its byte code into memory. It utilizes Java Compiler API (javax.tools). This library can be used by any dynamic java application, that needs compile and load java sources at runtime.
Usage:
Simple source compilation
```java
JavaSourceCompiler javaSourceCompiler = new JavaSourceCompilerImpl();
JavaSourceCompiler.CompilationUnit compilationUnit = javaSourceCompiler.createCompilationUnit();
String javaSourceCode = "package com.test.foo;\n" +
"public class Foo {\n" +
" public static void main(String [] args) {\n" +
" System.out.println("Hello world");\n" +
" }\n" +
" }";
compilationUnit.addJavaSource("com.test.foo.Foo", sourceCode);
ClassLoader classLoader = javaSourceCompiler.compile(compilationUnit);
Class fooClass = classLoader.loadClass("com.test.foo.Foo");
```
Java sources compilation with dependencies
```java
JavaSourceCompiler javaSourceCompiler = new JavaSourceCompilerImpl();
JavaSourceCompiler.CompilationUnit compilationUnit = javaSourceCompiler.createCompilationUnit();
compilationUnit.addClassPathEntry("/Users/xxxx/.m2/repository/javax/inject/javax.inject/1/javax.inject-1.jar");
String iBarSource = "package com.test;\n" +
" public interface IBar {\n" +
" public void execute();\n" +
" }";
compilationUnit.addJavaSource("com.test.IBar", iBarSource);
String barSource = "package com.test;\n" +
"import javax.inject.Inject;\n" +
"public class Bar implements IBar {\n" +
" private final String message;\n" +
"\n" +
" @Inject\n" +
" public Bar(String message) {\n" +
" this.message = message;\n" +
" }\n" +
"\n" +
"\n" +
" @Override\n" +
" public void execute() {\n" +
" System.out.println(message);\n" +
" }\n" +
" }";
compilationUnit.addJavaSource("com.test.IBar", barSource);
ClassLoader classLoader = javaSourceCompiler.compile(compilationUnit);
Class iBar = classLoader.loadClass("com.test.IBar");
Class bar = classLoader.loadClass("com.test.Bar");
```
