> In trunk, these apis let you easily create a field, but my concern is this:
> {code}
> public NumericField(String name, int value)
> public NumericField(String name, long value)
> ..
> public Field(String name, int value, FieldType type)
> public Field(String name, long value, FieldType type)
> ..
> public void setValue(int value)
> public void setValue(long value)
> ..
> public DocValuesField(String name, int value, DocValues.Type docValueType)
> public DocValuesField(String name, long value, DocValues.Type docValueType)
> {code}
> I really don't like overloaded ctors/setters where the compiler can type-promote you,
> I think it makes the apis hard to use.
> Instead for the setters I think we sohuld have setIntValue, setLongValue, ...
> For the ctors, I see two other options:
> # factories like DocValuesField.newIntField()
> # subclasses like IntField
> I don't have any patch for this, but I think we should discuss and fix before these apis
are released.
