Detailed Description
This is the base class of all tables within a database. A table is defined by a set of columns, which can be added and removed dynamically. The columns might have default values. Those are stored with the table, as well. The columns all consist of objects of class_VDBL_col.
The whole table then consists of a set of rows (_VDBL_row objects), organized in a map rowid -> row.

Member Function Documentation
| virtual std::pair<std::string,_VDBL_colid> _VDBL_table::_next_col | ( | const std::pair< std::string, _VDBL_colid > & | _ci | ) | const [inline, virtual] |
This virtual function has to be overloaded by the derived table classes, and it performs the step to the next column for a _col_iterator. This virtual function has to be overloaded by the derived table classes, and it performs the step to the previous column for a _col_iterator. return iterator to first column return iterator beyond last column This is the fundamental class for iterators over all rows, defining basic in(de)crementation for overloading, and basic comparison.
Reimplemented in _VDBL_standardtable.

| virtual _VDBL_rowid _VDBL_table::_next_row | ( | const _VDBL_rowid & | _ci | ) | const [inline, virtual] |
This virtual function has to be overloaded by the derived table classes, and it performs the step to the next row for a _col_iterator. This virtual function has to be overloaded by the derived table classes, and it performs the step to the previous row for a _col_iterator. return iterator to first row return iterator beyond last row construct a new copy of a row iterator standard constructor
Reimplemented in _VDBL_standardtable.

| _VDBL_colid _VDBL_table::get_colid | ( | ) | [inline, protected] |
generate new unique id's for rows and columns
Definition at line 99 of file vdbl_table.h.
| virtual const std::type_info& _VDBL_table::get_colinfo | ( | const std::string & | _C_n, | |
| std::triple< bool, _VDBL_colid, _VDBL_colflags > & | _r | |||
| ) | const [inline, virtual] |
return the column information for column _C_n. the return value is a referenc 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. what was the id of the last change to the table
Reimplemented in _VDBL_standardtable.
Definition at line 116 of file vdbl_table.h.
| _VDBL_rowid _VDBL_table::get_rowid | ( | ) | [inline, protected] |
generate new unique id's for rows and columns
Definition at line 100 of file vdbl_table.h.
| bool _VDBL_table::insert_row | ( | const __SequenceCtrOut< __SequenceCtrIn< _T_colspec, AllocatorIn >, AllocatorOut > & | _rows | ) | [inline] |
insert a many new rows of specifications _rows into the table. The list of rows can be contained in any sequential STL container, which holds any other sequential STL container of column entries. The function returns true, if inserting was successful for all rows.
Definition at line 473 of file vdbl_table.h.
| void _VDBL_table::made_change | ( | ) | [inline, protected] |
increment the last_change counter.
Definition at line 106 of file vdbl_table.h.
| virtual _VDBL_table* _VDBL_table::new_copy | ( | ) | const [inline, virtual] |
clone method clone destructor method add a new column of name _C_n, which contains __c, and has column flags __f. The function returns true, if adding the column was successful. modify the column of name _C_n, to new contents __c, and new column flags __f. The function returns true, if modifying was successful. modify the contents of column of name _C_n The function returns true, if modifying was successful. modify the column flags of column of name _C_n The function returns true, if modifying was successful. remove the column _C_n from the table The function returns true, if erasing was successful. rename the column _C_old to new name _C_new. The function returns true, if renaming was successful. 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. insert a new row of specification _row into the table. The function returns true, if inserting was successful. insert a new row of specification _row into the table, and return the row id of the newly created row in _r. Take any sequential STL container to hold the row entries of the column. The function returns true, if inserting was successful.
