Reto Bachmann-Gmür closed CLEREZZA-511.
---------------------------------------
should have closed them earlier.
> allow access to individual SimpleLiteralFactory converters

> code in Scala could do with using the converters from the
> SimpleLiteralFactory, but when it does it is absolutely clear
> which converter is needed. Instead of just adding the converters to a hashmap
> I suggest adding giving each one of them names.
> This is already implemented at it works
> final static public TypeConverter<byte[]> BYTE_ARRAY_CONVERTER = new
> ByteArrayConverter();
> final static public TypeConverter<Boolean> BOOLEAN_CONVERTER = new
> BooleanConverter();
> final static public TypeConverter<Date> DATE_CONVERTER = new
> DateConverter();
> final static public TypeConverter<String> STRING_CONVERTER = new
> StringConverter();
> final static public TypeConverter<Integer> INTEGER_CONVERTER = new
> IntegerConverter();
> final static public TypeConverter<BigInteger> BIG_INTEGER_CONVERTER =
> new BigIntegerConverter();
> final static public TypeConverter<Long> LONG_CONVERTER = new
> LongConverter();
> final static public TypeConverter<Double> DOUBLE_CONVERTER = new
> DoubleConverter();
> final static public TypeConverter<UriRef> URIREF_CONVERTER = new
> UriRefConverter();
> final private static Map<Class<?>, TypeConverter<?>> typeConverterMap =
> new HashMap<Class<?>, TypeConverter<?>>();
> final static Class<? extends byte[]> byteArrayType;
> static {
> //what's this for?
> Collections.addAll(decimalTypes, xsdInteger, xsdInt, xsdByte,
> xsdShort);
> byte[] byteArray = new byte[0];
> byteArrayType = byteArray.getClass();
> typeConverterMap.put(byteArrayType, BYTE_ARRAY_CONVERTER);
> typeConverterMap.put(Date.class, DATE_CONVERTER);
> typeConverterMap.put(Boolean.class, BOOLEAN_CONVERTER);
> typeConverterMap.put(String.class, STRING_CONVERTER);
> typeConverterMap.put(Integer.class, INTEGER_CONVERTER);
> typeConverterMap.put(BigInteger.class, BIG_INTEGER_CONVERTER);
> typeConverterMap.put(Long.class, LONG_CONVERTER);
> typeConverterMap.put(Double.class, DOUBLE_CONVERTER);
> typeConverterMap.put(UriRef.class, URIREF_CONVERTER);
> }
> This then allows one to write code such as
> implicit def string2lit(str: String) = new PlainLiteralScala(str)
> implicit def date2lit(date: Date) =
> DATE_CONVERTER.createTypedLiteral(date)
> implicit def int2lit(int: Int) =
> INTEGER_CONVERTER.createTypedLiteral(int)
> implicit def bigint2lit(bint: BigInt) =
> BIG_INTEGER_CONVERTER.createTypedLiteral(bint.underlying())
> implicit def bigint2lit(bigInt: BigInteger) =
> BIG_INTEGER_CONVERTER.createTypedLiteral(bigInt)
> implicit def bool2lit(boolean: Boolean) =
> BOOLEAN_CONVERTER.createTypedLiteral(boolean)
> implicit def scalaBool2lit(boolean: scala.Boolean) =
> BOOLEAN_CONVERTER.createTypedLiteral(boolean)
> implicit def long2lit(long: Long) =
> LONG_CONVERTER.createTypedLiteral(long)
> implicit def double2lit(double: Double) =
> DOUBLE_CONVERTER.createTypedLiteral(double)
> Saving on the hash lookup and iterations in these cases where it really is
> not necessary
