$Author: $ This class holds the model information for the mapping of a class attribute to a column of the corresponding table.
The information held by a MCPAttribute object is : -# Name of the attribute. -name- -# Name of the column (DB Table). -valueClassName- -# Class type used for the attribute (Class). -columnName- -# Type used in the database. -externalType- -# The width of the column (as defined for the DB). -width- or -precision- -# Is the column can be assigned NULL. -allowsNull- (a NSString with Y) -# Is the value of the column is auto-generated by the database at insert/update. -autoGenerated-
All this information is generated from a dictionary containing the key/value pairs: - name : (NSString*) the name of the attribute. - valueClassName : (NSString*) the name of the class used for this attribute. - columnName : (NSString*) the name of the correpsonding column in the table. - externalType : (NSString*) the name of the type used in the database. - precision or width : (NSNumber*) the width of the field in the database. - allowsNull : (NSString*) "Y" if the DB field allow NULL values. - autoGenerated : (NSString*) "Y" if the DB field is auto generated at insert/update time.
