public Class DecimalFormatNumberMatcher

Class Inheritance

extends Object
implements NumberMatcher

java.lang.Object
uk.ac.ed.ph.snuggletex.DecimalFormatNumberMatcher

All Implemented Interfaces

uk.ac.ed.ph.snuggletex.NumberMatcher

Imports

java.math.BigDecimal, java.text.DecimalFormat, .DecimalFormatSymbols, .ParsePosition, java.util.Locale

Implementation of NumberMatcher that uses a standard Java DecimalFormat to match numbers.

By default, this uses the default DecimalFormat with the platform default Locale.

You will probably want your DecimalFormat to have grouping turned off, otherwise something like 1,2 (in UK locale) would be parsed as a number 12.
