Classes
class	Array< T >
	Safe arrays of arbitrary types.Class Array provides safe arrays of arbitrary type. Array elements are accessed just like ordinary C++ array elements by means of the index operator[](). Safety is provided by. More...
class	ClassArray< T >
	Safe arrays of class objects.Class ClassArray provides safe arrays of general C++ objects (in contrast to data objects). The elements of an instance of ClassArray can be accessed just like ordinary C++ array elements by means of the index operator[](). Safety is provided by. More...
class	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. More...
class	DataHashTable< HashItem, Info >
	Generic hash table for data objects.Class DataHashTable provides a generic hash table for Data Objects, i.e., a map that maps arguments called HashItems to values called Infos. HashItem and Info types are passed as template arguments. HashItems must provide a comparison operator==(). Furthermore, both the HashItem and Info must be data objects in the sense that the assignment operator is equivalent to a memcpy() of the structure and no destructor is required. More...
class	DataKey
	Entry identifier class for items of a DataSet.Every item in a DataSet is assigned a DataKey by which it can be accessed (using DataSet::operator[]()). A DataKey consists of an integer member idx, which is a positive number for any valid DataKey. No idx of an element in a DataSet may exceed the sets max(). This property may be used to build arrays with additional information to the elements of a DataSet. More...
class	DIdxSet
	Dynamic index set.Class DIdxSet provides dynamic IdxSet in the sense, that no restrictions are posed on the use of methods add(). However, method indexMem() has been moved to the private members. This is because DIdxSet adds its own memory management to class IdxSet and the user must not interfere with it. More...
class	SPxException
	Exception base class.This class implements a base class for our SoPlex exceptions We provide a what() function which returns the exception message. More...
class	SPxMemoryException
	Exception class for out of memory exceptions.This class is derived from the SoPlex exception base class. It does not provide any new functionality. More...
class	SPxStatusException
	Exception class for status exceptions during the computationsThis class is derived from the SoPlex exception base class. It does not provide any new functionality. More...
class	SPxInternalCodeException
	Exception class for things that should NEVER happen.This class is derived from the SoPlex exception base class. It does not provide any new functionality. Most often it is used to replace assert(false) terms in earlier code. More...
class	SPxInterfaceException
	Exception class for incorrect usage of interface methods. More...
class	IdElement< T >
	Elements for IdLists.IdElements are derived from the template parameter class T and can hence be used as such. The additional methods next() and prev() provide access to the links for the list. They may freely be used by the programmer as long as an IdElement is not member of a IdList. In this case, the IdList controls members next() and prev(). However, IdList should provide enough functionality for the user not to require any modification to these members. More...
class	IdList< T >
	Generic Real linked list.Class IdList implements an intrusive Real linked list as a template class. As such, the list elements must provide the links themselfs. For conveniance, we also provide class IdElement that adds both links to an arbitrary class as template parameter. More...
class	IdxSet
	Set of indices.Class IdxSet provides a set of indices. At construction it must be given an array of int where to store the indice and its length. The array will from then on be managed by the IdxSet. More...
class	IsElement< T >
	Elements for IsLists.Class IsElement allows to easily construct list elements for an intrusive single linked list IsList out of a template class T. It adds a next pointer to each element. An instance of IdElement<T> a can be used just like an instance of T itself, except that method next() has been added (thereby overriding any method next() defined in T). More...
class	IsList< T >
	Generic single linked list.Class IsList implements an intrusive single linked list of elements of a template class T. As an intrusive list, the objects of type T must provide methods next() for setting and inquiring a pointer to the next element in a list. The user is responsible for not modifying the next() pointer of elements currently residing in a list, which may destroy the lists integrity. For this, class IsList provides enough methods for modifying a list in a save way. See the method list for a description. More...
class	NameSet::Name
	Handles of names in a NameSet.Class Name provides the handles (i.e., char*s) of names in a NameSet. More...
class	Random
	Random numbers.Class Random provides random Real variables, i.e. a value variable that gives another value each time it is accessed. It may be used just like an ordinary Real by means of an overloaded cast operator Real()%. More...
class	ClassSet< T >
	Set of class objects.Class ClassSet manages of sets of class objects of a template type T. For constructing a ClassSet the maximum number of entries must be given. The current maximum number may be inquired with method max(). More...
class	DataSet< DATA >
	Set of data objects.Class DataSet manages of sets of data objects of a template type DATA. For constructing a DataSet the maximum number of entries must be given. The current maximum number may be inquired with method max(). More...
class	NameSet
	Set of strings.Class NameSet implements a symbol or name table. It allows to store or remove names (i.e., char*), but does not provide means for manipulating stored names. More...
class	SPxOut
	Wrapper for several output streams. A verbosity level is used to decide which stream to use and whether to really print a given message. Regardless of whether the verbosity level is set via a manipulator or via the member function, it is persistent until a new value is set. More...
class	Timer
	Wrapper for the system time query methods. More...
class	TimerFactory
	Class to create new timers and to switch types of exiting ones. More...

Detailed Description

General purpose classes.

Elementary classes are provided for general purpose use in projects way beyond the scope of numerical software or linear programming.
