Examples of org.apache.ws.jaxme.js.DirectAccessible

org.apache.ws.jaxme.js.DirectAccessible
This interface is an abstract base for fields and similar objects. It doesn't define many methods, it mainly indicates, that the implementations value is directly and fast accessible in the generated code. The use is best demonstrated by an example. Suggest the following piece of code:
```
 Object value; return new Object[]{"((", value, ") * (", value, "))"}; 
```
The example is well suited for the case, where value is a variable name like "i". It is not suited, if "value" contains an expensive method call like "sin(x)". It is even wrong in the case "i++".

By using the interface DirectAccessible, you can change the implementation of getSquare() to look like this:
```
 Object value; JavaQName type; if (!(value instanceof DirectAccessible)) { LocalJavaField v = pMethod.newJavaField(type); v.addLine(value); v.setFinal(true); value = v; } return new Object[]{"((", value, ") * (", value, "))"}; 
```
This results in code, which is far more readable and better optimized.
