Hello,<br>
<br>
I've tried Luca's method and it works with ShapeFile.<br>
<br>
Thanks<br>

<pre wrap="">Did you try using Luca's method? It _should_ work - basically we made
access to such things more generic. If it doesn't work with shapefile
then it's a bug - make a JIRA task for it, against 2.1.0, since it
really should be in the release.

<pre wrap="">Hello,
In fact, i've develop a small batch to import shape into MySQL 4.1.
I need a 'getFieldLength()' method in order to create SQL CREATE
statement (e.a create table network (name varchar(70), ...).
It could be usefull to add a convenience method to access this
information or access the metadata of the dbf.
Thank you to take care of our suggestions.
Regards

This was done to provide a more consistent method so specify
restrictions (length was being used semantically for different
operations on different datastores).
If people are missing these, perhaps we should consider adding some
utility methods (like the one below) for common use cases. I would
consider adding them to the FeatureTypes class ... or new utility
class called AtributeTypes.

Well, you're not the one who misses this handy method...
Here is a workaround:
private int getFieldLength(AttributeType attr, int
defaultLength)
{
int length = -1;
Filter f = attr.getRestriction();
if(f !=null && f!=Filter.ALL && f != Filter.NONE &&
(f.getFilterType() == f.COMPARE_LESS_THAN || f.getFilterType() ==
f.COMPARE_LESS_THAN_EQUAL)){
try{
CompareFilter cf = (CompareFilter)f;
if(cf.getLeftValue() instanceof LengthFunction){
length =
Integer.parseInt(((LiteralExpression)cf.getRightValue()).getLiteral().
toString());
}else{
if(cf.getRightValue() instanceof
LengthFunction){
length =
Integer.parseInt(((LiteralExpression)cf.getLeftValue()).getLiteral().t
oString());
}
}
}catch(NumberFormatException e){
length = defaultLength;
}
}else{
length = defaultLength;
}
return length;
}

Hello,
Is it possible to have a response about getFieldLength() in
AttributeType? This method does not exist any more, how can i do to
obtain this information in 2.1M5 ?
Thank you.
