Class NewlineReductionServletWriter

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.
