omitUnchangedText

public CaseMap.Lower omitUnchangedText()

Returns an instance that behaves like this one but omits unchanged text when case-mapping with Edits.

指定者:

omitUnchangedText 在类中 CaseMap

返回:

an options object with this option.

apply

public String apply(Locale locale,
                    CharSequence src)

参数:

locale - The locale ID. Can be null for Locale#getDefault. (See ULocale#toLocale.)

src - The original string.

返回:

the result string.

apply

public <A extends Appendable> A apply(Locale locale,
                                      CharSequence src,
                                      A dest,
                                      Edits edits)

Lowercases a string and optionally records edits (see omitUnchangedText()). Casing is locale-dependent and context-sensitive. The result may be longer or shorter than the original.

参数:

locale - The locale ID. Can be null for Locale#getDefault. (See ULocale#toLocale.)

src - The original string.

dest - A buffer for the result string. Must not be null.

edits - Records edits for index mapping, working with styled text, and getting only changes (if any). This function calls edits.reset() first. edits can be null.

返回:

dest with the result string (or only changes) appended.
