I am a bit confused on how I can get the attributes width.
I have a component which I pass a generic EOEnterpriseObject to.
Since, this
component only affects certain objects which all contain an attribute
called "name",
I need to find the maximum defined width.
However I couldn't seem to find in the api the place where I can get
an attribute
from a string, i.e, "name" of that enterprise object.
Hi James,
All that stuff is held in the model classes: EOEntity, EOAttribute,
EORelationship...
First you need to get an EOEntity for your eo. Simplest would be to
use the method in com.webobjects.eoaccess.EOUtilities:
myEntity = EOUtilities.entityForObject(myEditingContext, myEO);
Then, it is a simple matter to get the EOAttribute:
myAttribute = myEntity.attributeNamed("name");
And finally, the width:
width = myAttribute.width();
HTH!
