Detailed Description

Defines the contract to access the data contained into a table of a database.

Default implementations of this interface are set to be read-only: to make the table accessible in write-mode, tables will implement IMutableTable.

A table rows can be enumerated in a sequence mode by using the IEnumerable<Row>, but if the table is altered the enumeration will throw an exception.

ColumnIndex Deveel.Data.Sql.Tables.ITable.GetIndex

(

int

columnOffset

)

Gets an index for given column that can be used to select values from this table.

Parameters

columnOffset

The zero-based offset of the column which to get the index.

Returns

Returns an instance of ColumnIndex that is used to select a subset of rows from the table.

Implemented in Deveel.Data.Sql.Tables.TableSource.MinimalTable, Deveel.Data.Transactions.TransactionTable, Deveel.Data.Sql.Tables.Table, and Deveel.Data.Sql.Tables.GeneratedTable.

DataObject Deveel.Data.Sql.Tables.ITable.GetValue	(	long	rowNumber,
		int	columnOffset
	)

Gets a single cell within the table that is located at the given column offset and row.

Parameters

rowNumber	The unique number of the row where the cell is located.
columnOffset	The zero-based offset of the column of the cell to return.

Returns

Returns an instance of DataObject that is contained in the cell located by the row and column coordinates provided.

Exceptions

ArgumentOutOfRangeException

If the given columnOffset is less than zero or greater or equal than the number of columns defined in the table metadata.
