本文整理了Java中com.google.common.base.Ascii.equalsIgnoreCase()方法的一些代码示例，展示了Ascii.equalsIgnoreCase()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。Ascii.equalsIgnoreCase()方法的具体详情如下：
包路径：com.google.common.base.Ascii
类名称：Ascii
方法名：equalsIgnoreCase

Ascii.equalsIgnoreCase介绍

[英]Indicates whether the contents of the given character sequences s1 and s2 are equal, ignoring the case of any ASCII alphabetic characters between 'a' and 'z'or 'A' and 'Z' inclusive.

This method is significantly faster than String#equalsIgnoreCase and should be used in preference if at least one of the parameters is known to contain only ASCII characters.

Note however that this method does not always behave identically to expressions such as:

  • string.toUpperCase().equals("UPPER CASE ASCII")
  • string.toLowerCase().equals("lower case ascii")

due to case-folding of some non-ASCII characters (which does not occur in String#equalsIgnoreCase). However in almost all cases that ASCII strings are used, the author probably wanted the behavior provided by this method rather than the subtle and sometimes surprising behavior of toUpperCase() and toLowerCase().
[中]指示给定字符序列s1和s2的内容是否相等，忽略“a”和“z”或“a”和“z”之间的ASCII字母字符的大小写。
此方法比字符串#equalsIgnoreCase快得多，如果已知至少一个参数仅包含ASCII字符，则应优先使用此方法。
但是请注意，此方法的行为并不总是与表达式相同，例如：
*绳子。toUpperCase（）。等于（“大写ASCII”）
*绳子。toLowerCase（）。等于（“小写ascii”）
由于某些非ASCII字符的大小写折叠（在字符串#equalsIgnoreCase中不出现）。然而，在几乎所有使用ASCII字符串的情况下，作者可能希望使用此方法提供的行为，而不是toUpperCase（）和toLowerCase（）的微妙且有时令人惊讶的行为。

private static boolean containsValue(String expectedValue, List<String> actualValues) {
  final int numActualValues = actualValues.size();
  for (int i = 0; i < numActualValues; i++) {

      return true;
    }
  }
  return false;
