Bug 37909 – Call sites of TextIterator constructor are difficult to read

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Shinichiro Hamaji]

As suggested in Bug 36419, TextIterator and CharacterIterator are instantiated with confusing boolean parameters. Let's use enum version of their constructor and eliminate the old constructors.

I'm planning to change the names of boolean members of these classes (e.g., m_emitCharactersBetweenAllVisiblePositions). They should be third person singular.

I think these repeat the word "Behavior" too much. I would call these:

    TextIteratorDefaultBehavior = 0,
    TextIteratorEmitsCharactersBetweenAllVisiblePositions = 1 << 0,
    TextIteratorEntersTextControls = 1 << 1,
    TextIteratorEmitsTextWithoutTranscoding = 1 << 2,

r=me, whether or not you change the names

Thanks Darin for your review. I changed the name of enum values as you suggested.
