Member Function Documentation

void* _VDBL_hierarchicalview::_copy_col_data ( void * _d ) const [inline, protected, virtual]

This function copies the additional data needed by a _col_iterator This virtual function has to be overloaded by the derived view classes, and it performs the step to the next row for a _row_iterator. This virtual function has to be overloaded by the derived view classes, and it performs the step to the previous row for a _row_iterator. This function destroys the additional data needed by a _row_iterator

Reimplemented from _VDBL_view.

Definition at line 290 of file vdbl_hrview.h.

void* _VDBL_hierarchicalview::_copy_def_data ( void * _d ) const [inline, protected, virtual]

This function copies the additional data needed by a _default_iterator This virtual function has to be overloaded by the derived view classes, and it performs the step to the next column for a _col_iterator. This virtual function has to be overloaded by the derived view classes, and it performs the step to the previous column for a _col_iterator. This function destroys the additional data needed by a _col_iterator

Reimplemented from _VDBL_view.

Definition at line 233 of file vdbl_hrview.h.

void* _VDBL_hierarchicalview::_copy_row_data ( void * _d ) const [inline, protected, virtual]

This function copies the additional data needed by a _row_iterator This is the fundamental class for iterators over all default columns, defining basic in(de)crementation for overloading, and basic comparison.

Reimplemented from _VDBL_view.

Definition at line 327 of file vdbl_hrview.h.

std::triple<_VDBL_tableid,_VDBL_colid,void*> _VDBL_hierarchicalview::_next_def_col	(	const _VDBL_tableid &	_t,
		const _VDBL_colid &	_c,
		void *	_d
	)			const `[inline, protected, virtual]`

This virtual function has to be overloaded by the derived view classes, and it performs the step to the next default of a column a _default_iterator. This virtual function has to be overloaded by the derived view classes, and it performs the step to the previous default of a column a _default_iterator. This function destroys the additional data needed by a _default_iterator

template<class _TR >

bool _VDBL_hierarchicalview::get	(	const std::pair< _VDBL_tableid, _VDBL_rowid > &	_ri,
		const _VDBL_colid &	_ci,
		_TR &	r
	)			const `[inline]`

get the data from column _ci in row _ri.second of table _ri.first. The data stored in the column must be of type _TR.

Definition at line 651 of file vdbl_hrview.h.

template<class _TR >

bool _VDBL_hierarchicalview::get_raw_ptr	(	const std::pair< _VDBL_tableid, _VDBL_rowid > &	_ri,
		const _VDBL_colid &	_ci,
		_TR const *&	r
	)			const `[inline]`

get a const ptr to the data from column _ci in row _ri.second of table _ri.first. The data stored in the column must be of type _TR. In this function no data copying is done. Note that this function returns a pointer to the columns raw data, so it can only be used to refer to constant columns.

Definition at line 632 of file vdbl_hrview.h.

bool _VDBL_hierarchicalview::insert ( const std::vector< _T_colspec > & _row ) [inline]

for now window views can only make changes in the top table in the list of tables

Definition at line 506 of file vdbl_hrview.h.

virtual _VDBL_view* _VDBL_view::new_copy ( ) const [inline, virtual, inherited]

clone operation clone destructor return the column information for column _C_n. the return value is a reference to the type_info of the column's value type. The reference _r contains upon returning whether the function was successful, the column id, and the column flags. return a reference to the type_info of the column's value type. insert a new row of specification _row into the table, and return the row id of the newly created row in _r. The function returns true, if inserting was successful. remove the row with it _ri from the table return whether the column _C_n is defined in the table return table id and column id of column _C_n return column name of column _C_n return a const reference to the column with column id _ci in row _ri.second of table ri.first. If successful, set error to false, and to true otherwise. Note that in this function the context for the column is NOT set. This method adds the row ids in _rs to the visible part of the view. This method removes the row ids in _rs from the visible part of the view. print the contents of the column with column id _ci in row _ri.second of table ri.first. If the row is empty and no default is defined, print nothing. return a const reference to the row with row id _ri.second of table ri.first. If successful, set error to false, and to true otherwise. return a const reference to the default column with column id _ri.second of table ri.first. If successful, set error to false, and to true otherwise. return iterator to first default column return iterator beyond last default column return iterator to first row return iterator beyond last row return iterator to first column return iterator beyond last column return the type of this view

Definition at line 587 of file vdbl_view.h.

_VDBL_tableid _VDBL_hierarchicalview::pop_table ( ) [inline]

remove the topmost table from the view, and return its table id.

Definition at line 459 of file vdbl_hrview.h.

std::ostream& _VDBL_hierarchicalview::print_col	(	std::ostream &	o,
		const std::pair< _VDBL_tableid, _VDBL_rowid > &	_ri,
		const _VDBL_colid &	_ci,
		bool &	printed
	)			const `[inline]`

print the contents od column _ci in row _ri.second of table _ri.first.

Definition at line 606 of file vdbl_hrview.h.

void _VDBL_hierarchicalview::push_table	(	const _VDBL_tableid &	__ti,
		_VDBL_table *	__t,
		const std::vector< _VDBL_rowid > &	_rs
	)			`[inline]`

This pushes a new table onto the top of the hierarchical view stack. Additionally, a subset of the table's rows, which are visible in the view, can be specified.

Definition at line 434 of file vdbl_hrview.h.

void _VDBL_hierarchicalview::push_table	(	const _VDBL_tableid &	__ti,
		_VDBL_table *	__t
	)			`[inline]`

This pushes a new table onto the top of the hierarchical view stack.
