  27. of a data source in a <a name="org.positronicnet.content.ContentRepository" class="extype" href="ContentRepository.html">ContentRepository</a> ---
  28. currently, a SQLite database or Android ContentProvider.</p><p>NB that there are implicit conversions in the ContentValue
  29. companion object that coerce various primitive types to a
  30. <a name="org.positronicnet.content.ContentValue" class="extype" href="">ContentValue</a>, to facilitate
  31. their use with the org.postronicnet.content.ContentQuery
  32. API, etc. In addition to handling the usual primitives, this
  33. also allows use of Booleans, adhering to the recommended
  34. SQLite convention of converting them to an integer 0 (false)
  35. or 1 (true).</p><p>A further implementation note:</p><p>Android's Database API has two forms of binding: in a lot
  36. of places, you can stuff things into a contentValues, which
  37. holds typed objects --- but for bound variables in where
  38. clauses (the various selectionArgs arguments), you can supply
  39. only strings. Fortunately, it matters less than one might
  40. think, since the SQLite engine does conversions if you ask
  41. it to compare a number to a string. But it does mean that
  42. if you're implementing conversions of your own --- as we
  43. do with Booleans here, to implement the standard SQLite
  44. convention of representing them as 0 or 1 --- you have to
  45. specify the conversions both ways to keep it consistent.
