Examples of net.datacrow.core.objects.DcObject

net.datacrow.core.objects.DcObject
This class is what it is all about. Each DcObject represents an item within Data Crow. DcObjects are very generic by nature. There are no direct getters and setters for their values. Instead the values are stored in a Map object and the values are retrieved by using the field indices.
It's recommended before starting new development of plugins to create so called helper classes for your new module. Examples of helper classes are {@link Software}and {@link Movie}.
DcObjects are managed and maintained by the Data Manager class ( {@link DataManager}. Each DcObject belongs to a (@link {@link DcModule}). @author Robert Jan van der Waals
