Constructor & Destructor Documentation

te::da::Index::Index	(	DataSetType *	parent = `0`,
		unsigned int	id = `0`
	)

Constructor.

Parameters

dt	The DataSetType associated to this index.
id	The index identifier.

Postcondition: If dt is provided, the index will belong to the given DataSetType.; By default the index type is BTreeType.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

te::da::Index::Index	(	const std::string &	name,
		IndexType	t = `B_TREE_TYPE`,
		DataSetType *	dt = `0`,
		unsigned int	id = `0`
	)

Constructor.

Parameters

name	The index name.
t	The index type.
dt	The DataSetType associated to this index.
id	The index identifier.

Postcondition: If dt is provided, the index will belong to the given DataSetType.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!

Definition at line 40 of file Index.cpp.

References te::da::DataSetType::add(), and m_dt.

		IndexType	t,
		const std::vector< te::dt::Property * > &	properties,
		DataSetType *	dt = `0`,
		unsigned int	id = `0`
	)

Constructor.

Parameters

name	The index name.
t	The index type.
properties	The properties that form the index.
dt	The DataSetType associated to this index.
id	The index identifier.

Precondition: The properties must belong to the same DataSetType as the index.

Postcondition: If dt is provided, the index will belong to the given DataSetType.

Warning: The identifier value (id) may be used by data source implementations. So, don't rely on its value!
