Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

---

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

• TLDR: StreamingRenderer Symbolizers pre-processor extensions handling

Description

This proposal if for adding Symbolizers pre-processor extensions handling to StreamingRenderer class. This means StreamingRenderer class will contain a new configurable Symbolizers pre-processor collection allowing to add or remove instances as needed.

The interface SymbolizersPreProcessor will be implemented for handling and enhance the current Symbolizers list, adding new symbolizers at runtime. If no changes are applied to the current Symbolizers list, null or the former Symbolizers list can be returned.

SymbolizersPreProcessor interface definition:

Document to String, to file.

Document doc = getResultDoc();
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString();
