Class FastStringWriter

java.lang.Object

java.io.Writer

io.neba.core.util.FastStringWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class FastStringWriter
extends Writer

Unlike StringWriter, this Writer does not rely on a synchronized StringBuffer but on the efficient StringBuilder.
It is important to FastStringWriter(int) initialize this writer with the suitable capacity (=amount of expected characters) in order to maintain performance.
