Detailed Description

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.

Member Function Documentation

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.

Parameters
sinkThe error sink.
virtual IlBoolean IliTable::allowRowMove ( ) const
virtual

Returns IlTrue if the table (or subclass of the table) allows row move operations.

Returns
IlTrue if the table (or subclass of the table) allows row move operations.

Reimplemented in IliMemoryTable, and IliStringsTable.

IlInt IliTable::appendParameter ( const char *  paramName,
const IliDatatype type,
IlInt  maxlen = -1 
)

Appends a new parameter to the table parameters.

Parameters
paramNameThe parameter name, it is copied.
typeThe parameter type.
maxlenThe maximum length.
Returns
The position of the newly created parameter.
IlInt IliTable::appendRow ( IliTableBuffer tblBuf)

Appends a new row defined by the table buffer.

Parameters
tblBufThe table buffer.
Returns
The position of the new row, or -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.

Parameters
tblBufThe table buffer.
Returns
The position of the new row, or -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.
virtual IlBoolean IliTable::applyQueryMode ( IliTable queryTable)
virtual

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.

Parameters
queryTableThe table.
Returns
IlTrue if successful.

Reimplemented in IliSQLTable.

IliValue IliTable::at ( IlInt  rowno,
IlInt  colno 
) const

Returns a value.

Parameters
rownoThe row position.
colnoThe column position.
Returns
The value in the row positioned at rowno for the column positioned at colno. This member function is similar to the getValue() member function, except that it does not report any errors that may have occurred.
IliValue IliTable::at ( IlInt  rowno,
IliName  colname 
) const

Returns a value.

Parameters
rownoThe row position.
colnameThe name of the column.
Returns
The value in the row positioned at rowno for the column named colname.
virtual void IliTable::cellChanged ( IlInt  rowno,
IlInt  colno 
)
protectedvirtual

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.

Parameters
rownoThe row position.
colnoThe column position.
virtual IlBoolean IliTable::checkConstraints ( IlInt  rowno,
IliTableBuffer buff 
) const
virtual

Validates the table buffer data.

Parameters
rownoThe row position.
buffThe table buffer.
Returns
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 void IliTable::clearRows ( )
virtual

nameThe transaction manager name, it is created if it does not already exist.
void IliTable::sortRows ( const IlInt colnoArray,
IlInt  columnsCount,
IlInt  fromRow = 0,
IlInt  toRow = -1,
IliCompareFunction  fct = 0,
IlAny  data = 0 
)

Sorts a set of rows.

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() and IliDescOrder() are used to indicate the type of sort. Example:

// Sorts in the ascending order of column 2
// Sorts in the descending order of column 3
static const IlInt columns[] =
tbl->sortRows(columns, 2);
void sortRows(IlInt fromRow = 0, IlInt toRow = -1,
IlAny userdata = 0);
Parameters
colnoArrayThe column list.
columnsCountThe column count.
fromRowThe first row position.
toRowThe last row position.
fctThe function to compare. It uses to provide its own function to sort the rows.
dataThe user data that can be used to compare two rows.
virtual void IliTable::tableChanged ( )
protectedvirtual

Called when the IliTable object has undergone a significant number of changes.

It is much more efficient to call this member function after a number of changes, instead of calling one of the specific member functions (described below) after each change.

virtual IlBoolean IliTable::updateRow ( IlInt  rowno,
IliTableBuffer buff 
)
virtual

Updates a row with the values in the table buffer.

Not all the values are used to update the row. Instead the values for which the isModified() member function returns IlTrue, are used.

Note that this member function does not check any of the constraints defined in the schema. If the table (or subclass of the table) defines a mapping with a remote database, the row is also changed in the remote database.

Parameters
rownoThe row position.
buffThe table buffer.
Returns
IlTrue if successful and IlFalse if rowno is out of bounds, or if the row could not be updated.

Reimplemented in IliSQLTable, IliMemoryTable, and IliStringsTable.

virtual IlBoolean IliTable::updateRowInCache ( IlInt  rowno,
IliTableBuffer buff 
)
virtual

Updates a row.

This virtual member function is similar to the updateRow() member function except that it only updates the row in the local row cache if this table is a two-tier table.

Parameters
rownoThe row position.
buffThe table buffer.
Returns
IlTrue if successful and IlFalse if rowno is out of bounds, or if the row could not be updated.

Reimplemented in IliMemoryTable.

virtual void IliTable::write ( IL_STDPREF ostream &  output) const
virtual

Writes the definition of a schema to an output stream in a form suitable to be read back by the stream-based constructor.

Parameters
outputThe output stream.

Reimplemented from IliSchema.

Reimplemented in IliMemoryTable, IliMapTable, and IliStringsTable.

void IliTable::writeTable ( std::ostream &  output) const

Writes the definition of the table to an output stream, in a form suitable to be read back by the ReadTable() static member function.

This member function can write any subclass of IliTable.

Parameters
outputThe output stream.
