本文整理了Java中java.nio.charset.CoderResult.isOverflow()方法的一些代码示例，展示了CoderResult.isOverflow()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。CoderResult.isOverflow()方法的具体详情如下：
包路径：java.nio.charset.CoderResult
类名称：CoderResult
方法名：isOverflow

CoderResult.isOverflow介绍

[英]Returns true if this result is an overflow condition.
[中]如果此结果是溢出条件，则返回true。

代码示例

代码示例来源：origin: commons-io/commons-io

/**
 * Decode the contents of the input ByteBuffer into a CharBuffer.
 *
 * @param endOfInput indicates end of input
 * @throws IOException if an I/O error occurs
 */
private void processInput(final boolean endOfInput) throws IOException {
  // Prepare decoderIn for reading
  decoderIn.flip();
  CoderResult coderResult;
  while (true) {
    coderResult = decoder.decode(decoderIn, decoderOut, endOfInput);
    if (coderResult.isOverflow()) {
      flushOutput();
    } else if (coderResult.isUnderflow()) {
      break;
    } else {
      // The decoder is configured to replace malformed input and unmappable characters,
      // so we should not get here.
      throw new IOException("Unexpected coder result");
    }
  }
  // Discard the bytes that have been read
  decoderIn.compact();
}

  // characters (such as shifting back into a default state). In our implementation,
  // this is actually the first time ICU is told that we've run out of input.
