AnnotationIndex.iterator介绍

[英]Return an iterator over annotations that can be constrained to be unambiguous.

A disambiguated iterator is defined as follows. The first annotation returned is the same as would be returned by the corresponding ambiguous iterator. If the unambiguous iterator has returned a previously, it will next return the smallest b s.t. a < b and a.getEnd() <= b.getBegin(). In other words, the b annotation's start will be large enough to not overlap the span of a.

An unambiguous iterator makes a snapshot copy of the index containing just the disambiguated items, and iterates over that. It doesn't check for concurrent index modifications (the ambiguous iterator does check for this).
[中]在可以约束为明确的注释上返回迭代器。
消歧迭代器的定义如下。返回的第一个注释与相应的不明确迭代器返回的注释相同。如果明确的迭代器先前已返回a，那么它将接下来返回最小的bs.t.a<b和a.getEnd（）<=b.getBegin（）。换句话说，b注释的开始将足够大，不会与a的跨度重叠。
明确的迭代器生成索引的快照副本，其中只包含消除歧义的项，并对其进行迭代。它不检查并发索引修改（不明确的迭代器会检查这一点）。
