Exception Extensions for Java

##Exception Extensions

A library for giving you the exception handling you've always wanted.

###Usage Add the following static import:

import static com.techmale.exception_extension.ExceptionExtensions;

In it's simplest form:

IllegalArgumentException.when(condition, message);

// e.g.
IllegalArgumentException.when(myVar.equals("Foo"), "Bad value for myVar");

###Extending ####Adding your own Exceptions

import com.techmale.exception_extension.ExceptionExtensions;

public class MyApplicationExceptionExtensions{

    public static final ExceptionExtensions<InstantiationException> InstantiationException = new ExceptionExtensions(InstantiationException.class);

}

####Adding extra functionality

import com.techmale.exception_extension.ExceptionExtensions;

public class MyExceptionExtensions<T extends Exception> extends ExceptionExtensions<T> {

    public static final MyExceptionExtensions<IllegalArgumentException> IllegalArgumentException = new MyExceptionExtensions(IllegalArgumentException.class);

    protected MyExceptionExtensions(Class clazz) {
        super(clazz);
    }

    public void whenNot(boolean condition, String msg, Object... args) throws T {
        when(!condition,msg,args);
    }

}
