A general container for vector data.

This is a container for all data objects of the same type which may be used within SoS. A vector data object is described through a 'design' identifier and a 'quantity' identifier:

**quantity** A 'quantity' may be the x-direction of the stress tensor, the plastic strain or any other scalar physical quantity. **design** A 'design' is a single instantiation of the same quantity, i.e. if one has several measurements of the same quantity, each measurement represents a single design. Throughout the workflow of SoS one may add data sets which may be interpreted in terms of new designs or quantities. For example, the mean value or the standard deviation of a quantity is computed from a set of designs of the same quantity, and can be interpreted as a new design. Furthermore, one may define additional quantities, for example compute the von Mises equivalent stress from the 6-dimensional stress tensor (i.e. from 6 different quantities).

[DataObjectContainer](class_data_object_container.xhtml "A general container for vector data. ") is a Sender. It communicates to it's Listeners (Qt Datatables, [Structure](class_structure.xhtml "The central data structure for SoS. ")) when its DataObjects are changed (insert, erase, rename, change activity)

 [string\_vector\_type](class_data_object_container.xhtml#ac293ea0e5c280f69a497ea20f20c60b9) quantities  ( ) 

Generates a vector of strings containing all quantity idents being part in this filter.

Each quantity ident appears only once in the list. You can use this, for example, to find out which quantity names are selected.

ReturnsThe vector contained of quantity ident strings

 bool quantityExists  ( string  *quantity*) 

Check whether any DataObject with the given quantity ID exists. Worst case computational complexity is of order O( N\_designs \* log N\_quantities)

Parameters quantityThe design ID ReturnsTrue if a DataObject with the given quantity ID exists.

 renameDesign  ( string  *from\_name*,    string  *to\_name*   ) 

renames all design idents

NoteCreates copies of the DataObjects to be renamed and removes the original DataObjects from this [DataObjectContainer](class_data_object_container.xhtml "A general container for vector data. "). This favors data consistency over performance. Parameters from\_namethe original design ident to\_namethe new design ident. If it cannot be renamed (for example, if the names already exist in the data base) an exception is thrown. The data base may remain unchanged. After the renaming, the ordering of the data base will be adjusted to the new naming.
