Table class.
Library: dataccess
The IliTable
class is an abstract class that defines objects capable of managing an ordered collection of rows. Each of these rows conforms to the same schema. Since the IliTable
class is abstract, it defines a protocol for creating, editing, and inspecting a table object. This protocol is implemented in subclasses of the IliTable
class. In addition to having a schema, a table has a set of parameters. A table also manages a set of rows. Some of the IliTable
subclasses, such as IliMemoryTable
or IliStringsTable
, manage rows themselves. They are called one-tier tables. Other subclasses, such as IliSQLTable
, manage rows located in a remote database. They are called two-tier tables. Some of the member functions of the IliTable
class, behave differently in these two types of tables. It should be noted that a two-tier table implements a local row cache, where it stores a copy of some of the remote rows to which the table is mapped at any particular time. The purpose of this cache is to reduce communication overheads with the remote database engine, and to allow you to overcome the fact that many database systems do not provide random access to their data. In this situation, a subset of the database rows is copied and stored in the local row cache allowing the table object to provide random access to these rows. The IliTable
class does not support the concept of a current row. This is due to the fact that such a concept would not allow many users to simultaneously access the table, each with their own current row. Instead, a companion class, IliTableBuffer
, is provided. This class implements the notion of current row, allowing many simultaneous users of an IliTable
object.

void IliTable::addErrorSink | ( | IliErrorSink * | sink | ) |
Adds an error sink.
All errors that are thrown by one of the raiseError()
member functions will be forwarded to this error sink. Note that the table will not delete the error sink at destruction time, so the same error sink may be safely shared among many tables.
sink | The error sink. |
|
virtual |
Returns IlTrue
if the table (or subclass of the table) allows row move operations.
IlTrue
if the table (or subclass of the table) allows row move operations. Reimplemented in IliStringsTable, and IliMemoryTable.
IlInt IliTable::appendParameter | ( | const char * | paramName, |
const IliDatatype * | type, | ||
IlInt | maxlen = -1 |
||
) |
Appends a new parameter to the table parameters.
paramName | The parameter name, it is copied. |
type | The parameter type. |
maxlen | The maximum length. |
IlInt IliTable::appendRow | ( | IliTableBuffer * | tblBuf | ) |
Appends a new row defined by the table buffer.
tblBuf | The table buffer. |
-1
if it fails. If the table (or subclass of the table) defines a mapping with a remote database, the row is also inserted in the remote database. IlInt IliTable::appendRowInCache | ( | IliTableBuffer * | tblBuf | ) |
Appends a new row defined by the table buffer.
This member function is similar to the appendRow()
member function except that it appends only the row in the local row cache if this table is a two-tier table.
tblBuf | The table buffer. |
-1
if it fails. If the table (or subclass of the table) defines a mapping with a remote database, the row is also inserted in the remote database. Applies the query specified by the conditions contained in the provided table.
If query mode is supported, applies the query specified by the conditions contained in the queryTable()
parameter, which is expected to be a table obtained by calling the makeQueryTable()
virtual member function.
queryTable | The table. |
IlTrue
if successful. Reimplemented in IliSQLTable.
Returns a value.
rowno | The row position. |
colname | The name of the column. |
Returns a value.
rowno | The row position. |
colno | The column position. |
getValue()
member function, except that it does not report any errors that may have occurred. Called just after a cell has changed.
If more than one value has changed in a row, it is preferable to call the rowChanged()
member function once, instead of calling cellChanged()
many times.
rowno | The row position. |
colno | The column position. |
|
virtual |
Validates the table buffer data.
rowno | The row position. |
buff | The table buffer. |
IlTrue
if the buff table buffer contains a valid row as defined by the constraints specified in the schema of the table. If the rowno parameter is equal to -1
, the buff parameter is assumed to contain a row that will be inserted into the table. Otherwise, rowno must designate an existing row, and buff is assumed to contain a replacement for that row. The constraints that are checked by this member function are the primary key constraint, the NOT NULL
constraint, and the maximum length column constraint.
|
virtual |
Deletes all rows.
If the table (or subclass of the table) defines a mapping with a remote database, then only the rows in the IliTable
object are deleted. The rows in the remote database are not affected by this operation. This enables the row cache of such a table to be cleared.
Reimplemented in IliStringsTable, IliSQLTable, and IliMemoryTable.
IliTable* IliTable::copyTable | ( | ) | const |
Returns a copy of the table.

The means by which the lock can be released is not specified by class IliTable
. It is left to the discretion of subclasses (see class IliSQLTable
).
rowno | The row position. |

if the row was successfully refreshed and remotely locked. If this is a one-tier table, this member function returns IlTrue
without having any side effects. Reimplemented in IliSQLTable.

member function instead of rowChanged()
.

|
protectedvirtual |
Called just after a row has been removed from the table.
rowno | The row position. |
|
protectedvirtual |

IlTrue
if successful. Sets a value.
Changes the value in the column positioned at colno of the row positioned at rowno to value. This member function calls the updateRow()
member function. Note that if the table is a two-tier table (such as an IliSQLTable
object) and if more than one column must be changed at once, calling the set()
member function twice (once for each column) does not necessarily have the same effect as using a table buffer, assigning the two columns in the table buffer, and calling the updateRow()
member function once with that table buffer.

||
IlAny | data = 0 |
||
) |

Sorts all rows between position fromRow and position toRow. If toRow equals -1
, all rows starting at fromRow are sorted. The sorting order is defined by the colnoArray parameter, which designates an array of columnsCount column positions. Each given column is sorted in the ascending or descending order of the values. The global functions IliAscOrder()

fromRow | The first row position. |
toRow | The last row position. |
fct | The function to compare. It uses to provide its own function to sort the rows. |
