Class OjbCharBooleanFieldInverseConversion

  org.kuali.kfs.sys.dataaccess.OjbCharBooleanFieldInverseConversion

All Implemented Interfaces:

Serializable, org.apache.ojb.broker.accesslayer.conversions.FieldConversion

public class OjbCharBooleanFieldInverseConversion
extends Object
implements org.apache.ojb.broker.accesslayer.conversions.FieldConversion

This class is intended to be used for inverting all the boolean values stored in the database before loading them into the business object and vice versa. This functionality is necessary for situations where a database table stores the opposite of the intented boolean attribute. An example is where a given business object has a pre-defined attribute, such as "inactive", while the user wishes to display the value as an 'active' indicator rather than an 'inactive indicator. Ideally, it would be better to replace the field in the database with the appropriate representation of the data so we do not have to perform these confusing conversions on data. Unfortunately, this is not always an option.
