本文整理了Java中org.eclipse.persistence.internal.helper.Helper.releaseCalendar()方法的一些代码示例，展示了Helper.releaseCalendar()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。Helper.releaseCalendar()方法的具体详情如下：
包路径：org.eclipse.persistence.internal.helper.Helper
类名称：Helper
方法名：releaseCalendar

Helper.releaseCalendar介绍

[英]PERF: This is used to optimize Calendar conversion/printing. This should only be used when a calendar is temporarily required, when finished it must be released back.
[中]性能：用于优化日历转换/打印。仅当临时需要日历时才应使用此选项，完成后必须重新发布。

/**
 * Answer a Time with the hour, minute, second.
 * This builds a time avoiding the deprecated, inefficient and concurrency bottleneck date constructors.
 * The hour, minute, second are the values calendar uses,
 * i.e. year is from 0, month is 0-11, date is 1-31.
 */
