本文整理了Java中org.apache.sis.util.Utilities类的一些代码示例，展示了Utilities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。Utilities类的具体详情如下：
包路径：org.apache.sis.util.Utilities
类名称：Utilities

Utilities介绍

[英]Static methods for object comparisons in different ways (deeply, approximately, etc).
[中]以不同方式（深度、近似等）进行对象比较的静态方法。

代码示例

/**
 * Returns {@code true} if a candidate found by {@code IdentifiedObjectFinder} should be considered equals to the
 * requested object. This method invokes the {@code equals(…)} method on the {@code candidate} argument instead
 * than on the user-specified {@code object} on the assumption that implementations coming from the factory are
 * more reliable than user-specified objects.
 */

  return Utilities.deepEquals(candidate, object, ignoreAxes ? ComparisonMode.ALLOW_VARIANT : COMPARISON_MODE);
