[fdo-internals] New RFC 30 Posted

[Traian Stanev]

An alternative to this suggestion is to make the destination command accept an FdoIFeatureReader (or something equivalent that provides access to property values in a procedural way) as argument, rather than a collection of PropertyValues. I was thinking of this when I was implementing the SDF->SQLite converter, which requires two translations from PropertyValue to raw data - once when initializing the inputs of the insert command and a second time inside the destination provider when matching the input property values to the destination schema.

Hi Brent,
not directly related to this RFC but still it is important issue regarding FDO data values.

I find a problem working with FDO Readers and commands is that I need to get value as basic type from reader and then convert to FdoDataValue etc...
I would like to be able to use data values and properties with values from readers directly and make those as input value for another FDO command.
Right now I need to check data type returned from property get that data as native convert back to fdo data value and put as input to FDO command.

Hi,

RFC 30 (http://trac.osgeo.org/fdo/wiki/FDORfc30) is now ready for review. The main purpose is add FDO API functions to encapsulate conversions between different FDO data types. Please review and let me know if you have any questions or comments.

If approved, this one will likely be implemented 2 versions after FDO 3.3.

Thanks,
Brent.
