Member Function Documentation

void Deveel.Data.Sql.Tables.IMutableTable.AddLock ( )

Implemented in Deveel.Data.Transactions.TransactionTable, Deveel.Data.Transactions.Transaction.OldAndNewTableContainer.TriggeredOldNew, and Deveel.Data.Sql.Tables.UserContextTable.

RowId Deveel.Data.Sql.Tables.IMutableTable.AddRow ( Row row )

Persists a new row to the table.

The row to be added must belong to the table context, otherwise an exception will be thrown.

Parameters

row	The row to be persisted.

Returns: Returns a RowId that is the pointer to the row established in the table.

Exceptions

ArgumentException	If the gven row does not belong to the table context.
ArgumentNullException	If the given row is `null`.

Implemented in Deveel.Data.Transactions.Transaction.OldAndNewTableContainer.TriggeredOldNew, Deveel.Data.Transactions.TransactionTable, and Deveel.Data.Sql.Tables.UserContextTable.

void Deveel.Data.Sql.Tables.IMutableTable.AssertConstraints ( )

Performs all constraint integrity checks and actions to any modifications based on any changes that happened to the table since that last call to this method.

It is important that is called after any call to AddRow, RemoveRow or UpdateRow.

Any constraints that are marked as ConstraintDeferrability.InitiallyImmediate are checked when this is called, otherwise the constraint is checked at commit time.

Any referential actions are performed when this method is called. If a referential action causes a modification to another table, this method is recursively called on the table modified.

If a referential integrity constraint is violated and a referential action is unable to maintain the integrity of the database, any changes made to the table are reverted.

Implemented in Deveel.Data.Transactions.Transaction.OldAndNewTableContainer.TriggeredOldNew, Deveel.Data.Transactions.TransactionTable, and Deveel.Data.Sql.Tables.UserContextTable.

void Deveel.Data.Sql.Tables.IMutableTable.FlushIndexes ( )

Flushes all changes made on this table to the backing index scheme.

This is used during the commit phase of this objects lifetime. The transaction control mechanism has found that there are no clashes and now we need to commit the current table view to the conglomerate. Because this object may not update index information immediately, we call this to flush all the changes to the table to the backing index set.

When this method returns, the backing index-set of this view will be completely up to date.

Implemented in Deveel.Data.Transactions.Transaction.OldAndNewTableContainer.TriggeredOldNew, Deveel.Data.Transactions.TransactionTable, and Deveel.Data.Sql.Tables.UserContextTable.

void Deveel.Data.Sql.Tables.IMutableTable.RemoveLock ( )

Implemented in Deveel.Data.Transactions.TransactionTable, Deveel.Data.Transactions.Transaction.OldAndNewTableContainer.TriggeredOldNew, and Deveel.Data.Sql.Tables.UserContextTable.

bool Deveel.Data.Sql.Tables.IMutableTable.RemoveRow ( RowId rowId )

Deletes row identified by the given coordinates from the table.

Parameters

rowId The unique identifier of the row to be removed.
