<A extends Appendable> A	apply(CharSequence src, A dest, Edits edits) Case-folds a string and optionally records edits (see CaseMap.Fold.omitUnchangedText()).
CaseMap.Fold	omitUnchangedText() Returns an instance that behaves like this one but omits unchanged text when case-mapping with Edits.

omitUnchangedText

public CaseMap.Fold omitUnchangedText()

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

Specified by:

omitUnchangedText in class CaseMap

Returns:

an options object with this option.

turkic

public CaseMap.Fold turkic()

Returns an instance that behaves like this one but handles dotted I and dotless i appropriately for Turkic languages (tr, az).

Uses the Unicode CaseFolding.txt mappings marked with 'T' that are to be excluded for default mappings and included for the Turkic-specific mappings.

Returns:

an options object with this option.

apply

public String apply(CharSequence src)

Case-folds a string. The result may be longer or shorter than the original.

Case-folding is locale-independent and not context-sensitive, but there is an option for whether to include or exclude mappings for dotted I and dotless i that are marked with 'T' in CaseFolding.txt.

Parameters:

src - The original string.

Returns:

the result string.

UCharacter.foldCase(String, int)

apply

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

Case-folds a string and optionally records edits (see CaseMap.Fold.omitUnchangedText()). The result may be longer or shorter than the original.

Case-folding is locale-independent and not context-sensitive, but there is an option for whether to include or exclude mappings for dotted I and dotless i that are marked with 'T' in CaseFolding.txt.

Parameters:

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.

Returns:

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