Dynamic Loader

Dynamic Loader is In Memory Java Compiler and classpath loader which enables to compile both java file and code string in memory and also provide support to load supportive jars in classpath which need to compile the dynamic code.

Example

In Memory Compilation..

public class SourceTest {

    @Test
    public void sourceCodeTest() throws Exception {
        
        StringBuilder sourceCode = new StringBuilder();
        sourceCode.append("package org.dvare.dynamic;\n");
        sourceCode.append("public class SourceTestClass {\n");
        sourceCode.append("   public String testMethod() { return \"inside test method\"; }");
        sourceCode.append("}");

        DynamicCompiler dynamicCompiler = new DynamicCompiler();

        if (DynamicCompiler.isJava9OrAbove()) {
            dynamicCompiler.addCompilerOption(DynamicCompilerOption.ADD_EXPORTS, "java.base/java.time=ALL-UNNAMED");
        }
        
        dynamicCompiler.addSource("org.dvare.dynamic.SourceTestClass", sourceCode.toString());
        Map<String, Class<?>> compiled = dynamicCompiler.build();
        Class<?> aClass = compiled.get("org.dvare.dynamic.SourceTestClass");
        Assert.assertNotNull(aClass);
        Assert.assertEquals(1, aClass.getDeclaredMethods().length);
        }
    }
