Method Detail

applyChanges

void applyChanges(commonj.sdo.DataObject datagraph)
                  throws MediatorException

Flush all changes made to the datagraph back to a data source. Equivalent to applyChanges(true, datagraph).

Parameters:

datagraph -

Throws:

MediatorException

applyChanges

void applyChanges(boolean sortUpdates,
                commonj.sdo.DataObject datagraph)
                  throws MediatorException

Flush all changes made to the datagraph back to a data source. If sortUpdates is true, updates to the database will be sorted to avoid referential integrity constraint violations.

Parameters:

sortUpdates -

datagraph -

Throws:

MediatorException

getGraph

commonj.sdo.DataObject getGraph()
                                throws MediatorException

Create a DataGraph and return its root data object

Returns:

the root data object in the data graph

Throws:

MediatorException

getGraph

commonj.sdo.DataObject getGraph(commonj.sdo.DataObject parameters)
                                throws MediatorException

Create a DataGraph with the given parameters and return its root data object

Parameters:

parameters -

Returns:

the root data object in the data graph

Throws:

MediatorException

getSchema

org.eclipse.emf.ecore.EClass getSchema()
                                       throws MediatorException

Return the datagraph schema

Returns:

the EClass for the root data object in the DataGraph

Throws:

MediatorException

getEmptyGraph

commonj.sdo.DataObject getEmptyGraph()
                                     throws MediatorException

Create an empty datagraph and return its root data object

Returns:

the root data object

Throws:

MediatorException

getKey

long getKey()
            throws MediatorException

Return a unique key value

Returns:

a unique key

Throws:

MediatorException

setConnectionWrapper

void setConnectionWrapper(ConnectionWrapper connectionWrapper)

Set the ConnectionWrapper object

Parameters:

connectionWrapper -

getConnectionWrapper

ConnectionWrapper getConnectionWrapper()

Get the ConnectionWrapper object

Returns:

the connection wrapper

getParameterDataObject

commonj.sdo.DataObject getParameterDataObject()
                                              throws MediatorException

Create and return a DataObject to be used by getGraph(DataObject). If generated select statements are being used, the DataObject will contain Properties for each FilterArgument defined in the Metadata. If the select statement has been supplied, the DataObject will contain a Property for each '?' placeholder in the select string. These properties will be named arg0,arg1,...,argn

Returns:

the data object

Throws:

MediatorException

setResultSetInfo

void setResultSetInfo(com.ibm.websphere.sdo.mediator.ResultSetInfo info)
                      throws MediatorException

Throws:

MediatorException
