Package com.ibm.websphere.rsadapter
Class DataStoreHelperMetaData
java.lang.Object
com.ibm.websphere.rsadapter.DataStoreHelperMetaData
This class provides metadata information for DataStoreHelpers. DataStoreHelperMetaData
can be used to retrieve static information about the database and JDBC driver.
Setter methods are provided only for the DataStoreHelper
class to use in initializing the DataStoreHelperMetaData.
The setter methods must never be used directly by the application.

setHelperType
public final void setHelperType(int hType) Configures the DataStoreHelepr type. A list of valid DataStoreHelper types is defined on the DataStoreHelper interface. For example,DataStoreHelper.DB2_UNIVERSAL_HELPER.- Parameters:
hType- a valid DataStoreHelper type constant defined on the DataStoreHelper interface.
-
getDatabaseDefaultIsolationLevel
public final int getDatabaseDefaultIsolationLevel()Returns the default transaction isolation level for the DataStoreHelper to which this DataStoreHelperMetaData corresponds.- Returns:

-
setDatabaseDefaultIsolationLevel
public final void setDatabaseDefaultIsolationLevel(int helperDefaultLevel, int cusDefinedWasDefaultIsoLevel) Configures an indicator of the default transaction isolation level for the JDBC driver. This method should be used only by the DataStoreHelper class to initially configure the DataStoreHelperMetaData.- Parameters:
helperDefaultLevel- the datastore helper default transaction isolation level. Transaction isolation level constants are defined on the java.sql.Connection interface.cusDefinedWasDefaultIsoLevel- value that overrides the helperDefaultLevel. Specify -1 to use the supplied helperDefaultLevel.- See Also:
-
