# Creating Objects
In many cases you will probably want your data to be returned as one of your domain objects. It would be wasteful to first create arrays and then convert all those. NeoCSV has non-intrusive options to create instances of your own classes and to convert and set fields on them directly. This is done by specifying accessors and converters. Here is an example for reading Associations of Floats.
(NeoCSVReader on: '1.5,2.2\4.5,6\7.8,9.1' withCRs readStream) recordClass: Association; addFloatField: #key:; addFloatField: #value:; upToEnd
recordClass: anObject "Set the object class to instanciate while reading records. Unless the objets are integer indexable, you have to specify fields as well." recordClass := anObject
