NewlineReductionServletWriter (Apache Tomcat 10.0.27 API Documentation)

java.lang.Object
- org.apache.jasper.compiler.ServletWriter
- - org.apache.jasper.compiler.NewlineReductionServletWriter

All Implemented Interfaces:

java.lang.AutoCloseable
```
public class NewlineReductionServletWriter
extends ServletWriter
```
This class filters duplicate newlines instructions from the compiler output, and therefore from the runtime JSP. The duplicates typically happen because the compiler has multiple branches that write them, but they operate independently and don't realize that the previous output was identical. Removing these lines makes the JSP more efficient by executing fewer operations during runtime.
