Interface IOdiInterfaceDataAccessHelper

Deprecated.

this class/method belongs to 11g SDK and is deprecated in 12c release. An interface that can be implemented to help with runtime data access for the sources and targets of an interface. Various subcomponents of the interface can be specified, and data access is set up for those subcomponents. For example a specific set of source data stores, filters, joins, target columns or target mappings may be specified.

Implementations of this interface are used for computing all information needed to perform a show data on any object of the interface.

                                    IInterfaceSubComponent[] pInterfaceSubComponents,

                             throws PhysicalSchemasConflictException,

                                    java.lang.ClassNotFoundException

Deprecated.

Creates a DataAccessInfo to retrieve a request and a connection to the data of the elements that are sent in pInterfaceSubComponents. The elements in this array can be any of these elements of the interface:
- SourceDataStore,
- TargetMapping,
- GenericClause (Join or Filter),
- SourceSet.
Note that if you want to retrieve the data from the target datastore, you need to add the DataSet for which you want the mappings. If the interface has only one dataset, it may be ommitted, though.

Parameters:

pOdiInstance - the current OdiInstance on which the interface is located

pInterfaceSubComponents - all the sub components that are to be part of the show data expression

pJMSCallBack - the JMS callback giving JMS information if it is a JMS connection

pCheckValidityOnly - if true then the request will not return any data but only check the validity of the generated SQL code

pCountLines - if true, then the request only counts the data for the selected elements

Returns:

a DataAccessInfo containing all information needed to show the data of the interface ojbects

Throws:

PhysicalSchemasConflictException - if two interface subcomponents are not on the same physical schema

InexistentMappingException - if there is a missing mapping from logical schema to physical schema

OdiConnectionNotFoundException - if the connection to the data could not be resolved because no component points to a physical connection

java.sql.SQLException - if the connection could not be established to the data

java.lang.ClassNotFoundException - if the driver for the data connection is missing
