包路径：edu.umd.cs.findbugs.ba.XField
类名称：XField

XField介绍

[英]Abstract representation of a field. Note that this is called "XField" to distinguish it from BCEL's Field class. Also, you can think of the "X" as expanding to "Instance" or "Static".

This interface and its implementations exist because Field objects in BCEL are awkward to deal with. They are not Comparable, it is difficult to find out what class they belong to, etc.

If the resolved() method returns true, then any information queried from this object can be assumed to be accurate. If the resolved() method returns false, then FindBugs can't find the field and any information other than name/signature/etc. cannot be trusted.
[中]字段的抽象表示。请注意，这被称为“XField”，以区别于BCEL的Field类。此外，您可以将“X”视为扩展到“实例”或“静态”。
这个接口及其实现之所以存在，是因为BCEL中的字段对象难以处理。它们是不可比较的，很难找出它们属于哪个阶级等等。
如果resolved（）方法返回true，则可以假定从此对象查询的任何信息都是准确的。如果resolved（）方法返回false，则FindBugs无法找到该字段，并且除了名称/签名/等之外的任何信息都不可信。
