Override Java function calls.

[formalizator]

Hi all!

Tried using Apache Poi for Java.
The was some suspicious behavior.

Cell cell =...;

cel.setCellValue(0); // Ceylon tries cal setCellValue(Boolean) instead of setCellValue(Integer)

There are both methods for Boolean and Integer. Can we omit type signature or this is natural?

[Gavin King]

Did you try:

cell.cellValue = 0;

setCellValue = 0 - gives an error.

Interface Cell have 6 overload functions:

setCellValue(boolean value)
setCellValue(java.util.Calendar value)

setCellValue(java.util.Date value)

setCellValue(double value)

setCellValue(RichTextString value)
setCellValue(java.lang.String value)

Ceylon chooses setCellValue(boolean value).

How correctly work with overload functions in Ceylon?

[Gavin King]

No I meant:

    cellValue = 0;

Wait. I you're trying to call:

setCellValue(double value)

Then you need to write setCellValue(1.0).

The expression 1 is of type Integer, not of type Float.

[Evgeniy Martin]

cellValue = 0 gives an error too.

[Gavin King]

Right, sure, as I just said, the first problem you need to fix is realizing that
"1" is not a Float and so can't be assigned to a Java double.

Float is work. But what about of integer?

[Nikolay Tsankov]

According to https://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Cell.html there is no such method setCellValue(Integer)

Yes, you right. Boolean bewilder me. Thanks a lot.
