[fdo-internals] New RFC 30 Posted

[Haris Kurtagic]

Right now from Reader we can't get PropertyValues only raw data.

To get Property value and property value collection which then could be
passed to another command would be of great help and remove some of
unnecessary  data conversions.

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.
