Interface RubyDateTimeParsedElementsQuery.DecimalFractionConverter

Enclosing class:

RubyDateTimeParsedElementsQuery<T>

public static interface RubyDateTimeParsedElementsQuery.DecimalFractionConverter

A converter for a decimal fraction to be stored as the required type in the result Map.

For example, the following implementation converts a decimal fraction into Ruby's Rational object in JRuby.

 import org.jruby.Ruby;
 import org.jruby.RubyRational;

 public class DecimalFractionToRationalConverter implements RubyDateTimeParsedElementsQuery.DecimalFractionConverter {
     public DecimalFractionToRationalConverter(final Ruby ruby) {
         this.ruby = ruby;
     }

     public Object convertDecimalFraction(final long integer, final int nano) {
         return RubyRational.newRational(this.ruby, ((long) integer * 1_000_000_000L) + (long) nano, 1_000_000_000L);
     }

     private final Ruby ruby;
 }
