| /** |
| * Process module for the configurations node used for remotely storing Fortress specific properties. |
| * Fortress places no limits on the number of unique configurations that can be present. The Fortress client will specify |
| * the preferred cfg node by name via a property named, {@link org.apache.directory.fortress.core.GlobalIds#CONFIG_REALM}. Each |
| * process using Fortress client is free to share existing node with other processes or create its own unique config |
| * instance using the methods within this class.<BR> |
| * This class does perform simple data validations to ensure data reasonability and the required fields are present.<BR> |
| * The {@link org.apache.directory.fortress.core.ant.FortressAntTask#addConfig()} method calls the {@link #add} from this class during initial base loads. |
| * Removal {@link org.apache.directory.fortress.core.ant.FortressAntTask#deleteConfig()} is performed when removal of properties is the aim.<BR> |
| * This class will accept {@link Properties}, and forward on to it's corresponding DAO class {@link ConfigDAO} for updating properties stored on behalf of Fortress. |
| * <p> |
| * Class will throw {@link SecurityException} to caller in the event of security policy, data constraint violation or system |
| * error internal to DAO object. This class will forward DAO exceptions ({@link org.apache.directory.fortress.core.FinderException}, |
| * {@link org.apache.directory.fortress.core.CreateException},{@link org.apache.directory.fortress.core.UpdateException},{@link org.apache.directory.fortress.core.RemoveException}), |
| * or {@link org.apache.directory.fortress.core.ValidationException} as {@link org.apache.directory.fortress.core.SecurityException}s with appropriate |
| * error id from {@link org.apache.directory.fortress.core.GlobalErrIds}. |
| * <p> |
| * This class performs simple data validation on properties to ensure length does not exceed 100 and contents are safe text. |
