包路径：java.util.function.Predicate
类名称：Predicate
方法名：isEqual

Predicate.isEqual介绍

[英]Returns a predicate that tests if two arguments are equal according to Objects#equals(Object,Object).
[中]返回一个谓词，根据Objects#equals（Object，Object）测试两个参数是否相等。

 *  Note:  the power comparison is based on the length of the include pattern
 *  and of the exclude patterns without the wildcards.
 *  Ideally the comparison should be done based on the depth
 *  of the match; that is to say how many file separators have been matched
 *  before the first ** or the end of the pattern.
 *
 *  IMPORTANT : this function should return false "with care".
 *
 *  @param name the relative path to test.
 *  @return true if there is no exclude pattern more powerful than
 *  this include pattern.
