Detailed Descriptiontemplate<class T> class soplex::DataArray< T > Safe arrays of data objects. Class DataArray provides safe arrays of Data Objects. For general C++ objects (in contrast to data objects) class Array is provided which manages memory in a C++ compliant way. The elements of an instance of DataArray can be accessed just like ordinary C++ array elements by means of the index operator[](). Safety is provided by
Moreover, DataArrays may easily be extended by inserting or appending elements to the DataArray or shrunken by removing elements. Method reSize(int n) resets the DataArrays length to A DataArray may be used as arguments for standard C functions requiring pointers through the use of get_ptr() and get_const_ptr(). Internally, a DataArray object allocates a block of memory that fits up to max() elements, only size() of them are used. This makes extension and shrinking methods perform better.
