本文整理了Java中org.bson.BSON类的一些代码示例，展示了BSON类的具体用法。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。BSON类的具体详情如下：
包路径：org.bson.BSON
类名称：BSON

BSON介绍

[英]Contains byte representations of all the BSON types (see the BSON Specification). Also supports the registration of encoding and decoding hooks to transform BSON types during encoding or decoding.
[中]包含所有BSON类型的字节表示形式（请参见BSON Specification）。还支持编码和解码挂钩的注册，以在编码或解码期间转换BSON类型。

代码示例

private Pattern toPattern(String regex, @Nullable String options) {
  Assert.notNull(regex, "Regex string must not be null!");
  return Pattern.compile(regex, options == null ? 0 : BSON.regexFlags(options));
}
