Constructor & Destructor Documentation

BaseTable::BaseTable ( )

Constructs an empty BaseTable

BaseTable::BaseTable ( const Resource & resource )

The constructor for a BaseTable with a a Resource that is registered in the mastercatalog.
This resource must have a name and an Id.
Code and description are optional.

See Also: IlwisObject; Resource

Parameters

resource The resource to use

Member Function Documentation

bool BaseTable::addColumn	(	const QString &	name,
		const IDomain &	domain
	)

virtual

adds a column to the current set of columns of this table
the name string must be unique and the domain must be valid.
if this collumn creates a duplicate nothing will happen.
the collumn will be filled with appropriate defaults depending on the domain

See Also: IDomain

Parameters

name	the name of a column must be unique among the columns
domain	the domain of the new column

Returns: true if the column is succesfully added, false if some error occurred. The nature of the error can be found in the issue logger

Implements Ilwis::Table.

Reimplemented in Ilwis::FlatTable, and Ilwis::DatabaseTable.

bool BaseTable::addColumn	(	const QString &	name,
		const QString &	domainname
	)

virtual

adds a column to the current set of columns of this table.
duplicate columns wil be skipped
The new collumn contents will be set to appropriate defaults depending on the domain
The name string must be unique in the set of collumns and the domainname must be valid

Parameters

name	the name of a column must be unique among the columns
domain	the domain of the new column

Returns: true if the column is succesfully added, false if some error occurred. The nature of the error can be found in the issue logger

Implements Ilwis::Table.

bool BaseTable::addColumn ( const ColumnDefinition & def )

virtual

adds a column to the column definitions.
ColumnDefinition must be valid.
The new column contents will be set to appropriate defaults depending on the domain

Parameters

def	The ColumnDefinition of the new column

Returns: true if succesful. Duplicate columns are not allowed

Implements Ilwis::Table.

Reimplemented in Ilwis::FlatTable.

quint32 BaseTable::columnCount ( ) const

virtual

returns the number of columns in a table.
cannot be negative.

Returns: columns in the table

Implements Ilwis::Table.

ColumnDefinition BaseTable::columndefinition ( const QString & nme ) const

virtual

retrieves the definition of the column with the given name.
if there is no collumn with that name an invalid ColumnDefinition will be returned.

See Also: ColumnDefinition

Parameters

nme	name of the column definition to be retrieved

Returns: a column definition or an invalid defintion if a non existing column was retrieved

Implements Ilwis::Table.

ColumnDefinition BaseTable::columndefinition ( quint32 index ) const

virtual

retrieves the definition of the column at the given index.
if there is no collumn at this index an invalid ColumnDefinition will be returned.

See Also: ColumnDefinition

Parameters

index index of the column definition to be retrieved

Returns: a column definition or an invalid defintion if a non existing column was retrieved

Implements Ilwis::Table.

ColumnDefinition & BaseTable::columndefinition ( quint32 index )

virtual

retrieves a reference to the definition of the column.
if there is no collumn at this index nullptr will be returned.

See Also: ColumnDefinition

Parameters

index index of the ColumnDefinition to be retrieved

Returns: a reference to columndefinition or an invalid defintion if a non existing column was retrieved

Implements Ilwis::Table.

void BaseTable::columndefinition ( const ColumnDefinition & coldef )

virtual

sets a new column definition. The new definition must be valid.

See Also: ColumnDefinition

Parameters

coldef the new ColumnDefinition to be set

Implements Ilwis::Table.

quint32 BaseTable::columnIndex ( const QString & nme ) const

protectedvirtual

Translates a String with a column name into a column index

Parameters

nme	the name of the column

Returns: the index of the column with the given name and iundef illegaal

Implements Ilwis::Table.

bool BaseTable::createTable ( )

virtual

Creates a table based on the definitions in the columndefinition members. Will load the data in the specified amount of collumns and rows

Returns: true if succesfull

Implements Ilwis::Table.

Reimplemented in Ilwis::DatabaseTable, and Ilwis::FlatTable.

IlwisTypes BaseTable::ilwisType ( ) const

virtual

Gives the IlwisTypes of this object

See Also: IlwisObject

Returns: the IlwisTypes of this IlwisObject

Implements Ilwis::IlwisObject.

bool BaseTable::isValid ( ) const

virtual

a BaseTable is valid if it has rows and columns

Returns: true when valid.

Reimplemented in Ilwis::FlatTable, and Ilwis::DatabaseTable.

bool BaseTable::merge	(	const IlwisObject *	obj,
		int	options
	)

virtual

Merges this BaseTable with another BaseTable. Requires the given object to be a BaseTable, and the object cannot be null or undefined ofcourse

See Also: TableMerger

Parameters

obj	the object this shouls merge with
options	options for the merging, see TableMerger

Returns: true if the merging succeeded
