java - 为什么在Eclipse插件的源文件中，很多变量的前缀都是 "f"？

Question

我正在浏览 Eclipse 插件的源代码(现在我正在研究 TextMergeView 类)，我注意到很多变量都以 f 开头。

我知道我们经常给接口(interface)加上前缀I，以便第一眼就很容易将它们识别为接口(interface)。但是 f 是什么意思？

这是一个片段:

......
private int fInheritedDirection;    // inherited direction
    private int fTextDirection;         // requested direction for embedded SourceViewer

    private ActionContributionItem fIgnoreAncestorItem;
    private boolean fHighlightRanges;

    private boolean fShowPseudoConflicts= false;

    private boolean fUseSplines= true;
    private boolean fUseSingleLine= true;
    private boolean fUseResolveUI= true;
    private boolean fHighlightTokenChanges = false;

    private String fSymbolicFontName;

    private ActionContributionItem fNextDiff;   // goto next difference
    private ActionContributionItem fPreviousDiff;   // goto previous difference
    private ActionContributionItem fCopyDiffLeftToRightItem;
    private ActionContributionItem fCopyDiffRightToLeftItem;

    private CompareHandlerService fHandlerService;

    private boolean fSynchronizedScrolling= true;
...

为什么这些变量以f开头？ f 作为前缀是什么意思？

它几乎肯定是“字段”的意思，但它明确反对Eclipse coding conventions :

Private class variables must not have any field prefix or suffix.

class Person
{
    private String name; // NOT private String _name;
    // NOT private String fName;
    // NOT private String name_;
    ...
}

我怀疑这段代码比编码约定旧...
