IloCPConstraintI

The class IloCPConstraintI simplifies writing a new constraint using IBM® ILOG® Concert Technology. You can use the macro ILOCPCONSTRAINTWRAPPER to create a subclass of the class IloCPConstraintI with up to 4 data members.

If you want to create a constraint class with more than 4 data members, you must explicitly define a subclass of the class IloCPConstraintI. To do this, you must:

define the subclass
add the macro ILOCPCONSTRAINTWRAPPERDECL in the class definition
write the constructor
add the macro ILOCPCONSTRAINTWRAPPERIMPL in the source file
define the virtual member function makeClone
define a function which creates an instance of the new subclass and returns a handle of this object (You must make a call to the static method initTypeIndex once before using the generated constraint. Therefore, it is recommended to include this call in the function.)
define the virtual member function extract.

You can use the example in ILOCPCONSTRAINTWRAPPER as a model for writing your own new constraint explicitly.

This constructor creates an instance of the class IloCPConstraintI. This constructor is called automatically in the constructor of its subclasses.

This destructor is called automatically by the destructor of its subclasses. It frees memory used by the invoking object.

This member function prints the invoking constraint on an output stream.

In general terms, in Concert Technology, the objects of a model must be extracted. This member function returns the internal constraint extracted for use by cp from the invoking constraint of a model.

This member function is called internally to duplicate the current constraint.

This member function forces the extraction of an array of interval sequence variables.

This member function forces the extraction of an array of interval variables.

This member function forces the extraction of an array of numerical variables.

This member function forces the extraction of an array of integer variables.

This member function forces the extraction of an interval sequence variable.

This member function forces the extraction of an interval variable.

This member function forces the extraction of a numerical (integer or continuous) variable.
