Example 1
public void process(Bound annotation, CtParameter<?> element) {
	final CtMethod parent = element.getParent(CtMethod.class);

	// Build if check for min.
	CtIf anIf = getFactory().Core().createIf();
	anIf.setCondition(getFactory().Code().<Boolean>createCodeSnippetExpression(element.getSimpleName() + " < " + annotation.min()));
	CtThrow throwStmt = getFactory().Core().createThrow();
	throwStmt.setThrownExpression((CtExpression<? extends Throwable>) getFactory().Core().createCodeSnippetExpression().setValue("new RuntimeException(\"out of min bound (\" + " + element.getSimpleName() + " + \" < " + annotation.min() + "\")"));
	anIf.setThenStatement(throwStmt);
	parent.getBody().insertBegin(anIf);
	anIf.setParent(parent);

	// Build if check for max.
	anIf = getFactory().Core().createIf();
	anIf.setCondition(getFactory().Code().<Boolean>createCodeSnippetExpression(element.getSimpleName() + " > " + annotation.max()));
	anIf.setThenStatement(getFactory().Code().createCtThrow("new RuntimeException(\"out of max bound (\" + " + element.getSimpleName() + " + \" > " + annotation.max() + "\")"));
	parent.getBody().insertBegin(anIf);
	anIf.setParent(parent);
