类 StringBuilderWriter

  • 所有已实现的接口:
    java.io.Closeable, java.io.Flushable, java.io.Serializable, java.lang.Appendable, java.lang.AutoCloseable
    public class StringBuilderWriter
extends java.io.Writer
implements java.io.Serializable
    Writer implementation that outputs to a StringBuilder.

    NOTE: This implementation, as an alternative to java.io.StringWriter, provides an un-synchronized (i.e. for use in a single thread) implementation for better performance. For safe usage with multiple Threads then java.io.StringWriter should be used.

    从以下版本开始:
    2.0
