Class FieldConstants

public class FieldConstants
extends java.lang.Object
extends java.lang.Object

Defines constants for Field

Currently this class defines key type for a Field in
a Source or Target
Following is a code example for using FieldConstants while creating a flat file source

       // create a vector to hold the fields
       Vector fields = new Vector();
       // create a field of type of integer and add to the vector of fields
       Field field1 = new Field("EmployeeID", "EmployeeID","", DataTypeConstants.INTEGER, "10", "0",
                                                                FieldConstants.PRIMARY_KEY, Field.FIELDTYPE_SOURCE, true);
       fields.add(field1);
       // create a field of type of string and add to the vector of fields
       Field field2 = new Field("LastName", "LastName","", DataTypeConstants.STRING, "20", "0",
                                                                FieldConstants.NOT_A_KEY, Field.FIELDTYPE_SOURCE, false);
       fields.add(field2);
       // create connection info for a flat file source and set the connection
       // properties (not demonstrated in the code)
       ConnectionInfo ffConn = new ConnectionInfo( SourceTargetTypes.FLATFILE_TYPE );
       // create a Source
       Source employeeSource = new Source( "Employee", "Employee", "This is Employee Table",
                                                                                                                                         "Employee", ffConn );
       // set the fields in the Source
       employeeSource.setFields( fields );
