Creates a UnicodeUnescaper. The constructor takes a list of options, only one type of which is currently available (whether to allow, error or ignore the semicolon on the end of a numeric entity to being missing).

For example, to support numeric entities without a ';':

new NumericEntityUnescaper(NumericEntityUnescaper.OPTION.semiColonOptional)

and to throw an IllegalArgumentException when they're missing:

new NumericEntityUnescaper(NumericEntityUnescaper.OPTION.errorIfNoSemiColon)

Note that the default behavior is to ignore them.

Parameters

options:NumericEntityUnescaper.OPTION[]

to apply to this unescaper

Tests whether the passed in option is currently set.

Parameters

option:NumericEntityUnescaper.OPTION

to check state of.

Returns:boolean

whether the option is set.

Translate a set of code points, represented by an int index into a CharSequence, into another set of code points. The number of code points consumed must be returned, and the only IOExceptions thrown must be from interacting with the Writer so that the top level API may reliably ignore StringWriter IOExceptions.

IOException:

if and only if the Writer produces an IOException.
