How to read a double instead of a float?

[franco graziosi]

Hi,

It is not very clear to me how to change implicit types. I see how to
avoid them (in common tasks - just comment out), but it is possible to
change them, specifically I would like floating point numbers be
returned as double instead if float, and possibly, if followed by '%'
divided by 100.

Is there some simple example to do this, or something similar?

Thanks,

franco

Hello,

the procedure:

1) instruct SnakeYAML that a scalar which matches a specific regular expression shall use your specific tag

\d+% -> !my_divided_float

2) instruct SnakeYAML how to create your business object (float) from the scalar (String) with the specific tag

You may find more info in the documentation:

http://code.google.com/p/snakeyaml/wiki/Documentation#Constructors,_representers,_resolvers 

Search tests for method "Yaml.addImplicitResolver(String tag, Pattern regexp, String first)" to see more examples.

I think, this is similar to what what you want to achieve:
