org.apache.derby.iapi.sql.execute
Interface ExecutionContext

All Superinterfaces:: org.apache.derby.iapi.services.context.Context

public interface ExecutionContext
extends org.apache.derby.iapi.services.context.Context

ExecutionContext stores the factories that are to be used by the current connection. It also provides execution services for statement atomicity.

Field Summary

static java.lang.String CONTEXT_ID
          this is the ID we expect execution contexts to be stored into a context manager under.

static int[] CS_TO_JDBC_ISOLATION_LEVEL_MAP


static java.lang.String[][] CS_TO_SQL_ISOLATION_MAP


static int READ_COMMITTED_ISOLATION_LEVEL


static int READ_UNCOMMITTED_ISOLATION_LEVEL


static int REPEATABLE_READ_ISOLATION_LEVEL


static int SERIALIZABLE_ISOLATION_LEVEL


static int UNSPECIFIED_ISOLATION_LEVEL


Method Summary

void beginStatement(org.apache.derby.iapi.sql.ResultSet sourceRS)
          Mark the beginning of a statement (INSERT, UPDATE, DELETE)

void endStatement()
          The end of a statement (INSERT, UPDATE, DELETE)

ExecutionFactory getExecutionFactory()
          Get the ExecutionFactory from this ExecutionContext.

ResultSetFactory getResultSetFactory()
          Get the ResultSetFactory from this ExecutionContext.

ResultSetStatisticsFactory getResultSetStatisticsFactory()
          Get the ResultSetStatisticsFactory from this ExecutionContext.

java.lang.Object[] siftForeignKeys(java.lang.Object[] fullList)
          Sifts the array of foreign key constraints for the ones which apply in the current context.

java.lang.Object siftTriggers(java.lang.Object triggerInfo)
          Sifts the triggers for the ones which apply in the current context.

Method Detail

getResultSetFactory

public ResultSetFactory getResultSetFactory()

Get the ResultSetFactory from this ExecutionContext.

getResultSetStatisticsFactory

public ResultSetStatisticsFactory getResultSetStatisticsFactory()
                                                         throws org.apache.derby.iapi.error.StandardException

Get the ResultSetStatisticsFactory from this ExecutionContext.

getExecutionFactory

public ExecutionFactory getExecutionFactory()

Get the ExecutionFactory from this ExecutionContext.

beginStatement

public void beginStatement(org.apache.derby.iapi.sql.ResultSet sourceRS)
                    throws org.apache.derby.iapi.error.StandardException

Mark the beginning of a statement (INSERT, UPDATE, DELETE)

endStatement

public void endStatement()
                  throws org.apache.derby.iapi.error.StandardException

The end of a statement (INSERT, UPDATE, DELETE)

siftForeignKeys

public java.lang.Object[] siftForeignKeys(java.lang.Object[] fullList)
                                   throws org.apache.derby.iapi.error.StandardException

Sifts the array of foreign key constraints for the ones which apply in the current context. In certain contexts (e.g., when applying the COPY file or when tearing-off a new table during REFRESH), we don't want to not bother enforcing some foreign keys.

siftTriggers

public java.lang.Object siftTriggers(java.lang.Object triggerInfo)
                              throws org.apache.derby.iapi.error.StandardException

Sifts the triggers for the ones which apply in the current context. In certain contexts (e.g., when applying the COPY file or when tearing-off a new table during REFRESH), we don't want to not bother firing triggers.
