Classes

class  flopc::MP_boolean
 Reference counted class for all "boolean" types of data.

This contains counters to ConstantBase pointers. These pointers may be of any of the Boolean_base * type. This can be a constant valued boolean as well. explain SUBSETREF explain using pointer in -- should be private? More...

class  flopc::MP_constraint
 Semantic representation of a linear constraint.

This is one of the main public interface classes. It is always constructed through operator overloading between expressions, constants, and variables. There are many 'friend' overloaded operators to do the constuction. The basic idea is to make the constraint look like a paper-model constraint in C++ code. Once constructed, it should be added to the model. More...

class  flopc::MP_data
 Input data set.

This is one of the main public interface classes. It is normally directly constructed given a set of indices (domain) over which it is valid. If the data is not bound at construction, either the value() or initialize() method must be called which (deep) copies in the actual data. If one wishes to refer to external data instead rather than doing a deep copy, use the constructor which takes the value pointer as an argument. This copies the original data pointer value (rather than a deep copy).
This is used for construction of :. More...

class  flopc::MP_domain
 Range over which some other constuct is defined.

This is one of the main public interface classes. One uses this in the context of a constraint, objective, variable, or data. It is usually used in conjunction with an MP_set, or a subset, but can be used without one. It is the range over which the other construct is defined. More...

class  flopc::MP_domain_set
 Range over which some other constuct is defined.

This is one of the main public interface classes. One uses this in the context of a constraint, objective, variable, or data. This class in the MP_domain family uses an MP_set and and index for defining the Range over which the construct is defined. More...

class  flopc::MP_domain_subset< nbr >
 Range over which some other constuct is defined. Uses subsetting.

This is one of the main public interface classes. One uses this in the context of a constraint, objective, variable, or data. This class in the MP_domain family uses an MP_subset and a vector of indexes for defining the Range over which the construct is defined. More...

class  flopc::MP_expression
 Symbolic representation of a linear expression.

This is one of the main public interface classes. It is the basis for all linear expressions, including constraints, objective function, and expressions involving indexes.
Although these can be created directly and independently, it is expected these will be created through the use of the operators which are later in this file. (operator+, operator-, etc.). More...

class  flopc::MP_index
 Representation of an index.

This is one of the main public interface classes. It is used to iterate through, or index into an MP_domain. It is also used to share the 'current' index offsets between expressions which share an index. More...

class  flopc::MP_index_exp
 Representation of an expression involving an index.

This is one of the main public interface classes. It is used to create complex arrangements of index values.
Index expressions can involve:. More...

class  flopc::Messenger
 Inteface for hooking up to internal flopc++ message handling.

In more advanced use of FlopC++, it may be desirable to get access to internal calls for messages. In essence, sub-class this Messenger class, and register it with the MP_model. Also overload whichever message events you wish to handle. More...

class  flopc::MP_model
 This is the anchor point for all constructs in a FlopC++ model.

The constructors take an OsiSolverInterface, and (optionally) a replacemente for the Messenger class. There are some built-in changes to the verbosity for output.
The main methods to use are:. More...

class  flopc::MP_set
 Representation of a set for indexing into some other construct.

This is one of the main public interface classes. One uses this when constructing MP_domains, and subsets. It is frequent that one would directly construct sets of indices, then use expressions to subset or slice the data. More...

class  flopc::MP_variable
 Symantic representation of a variable.

This is one of the main public interface classes. It should be directly declared by clients of the FlopC++. The parametersof construction are MP_set s which specify the indexes over which the variable is defined. More...

class  flopc::MP_binary_variable
