Here are the classes, structs, unions and interfaces with brief descriptions:

CBcpsBranchObject	BcpsBranchObject contains the member data required when choosing branching entities and excuting actual branching
CBcpsBranchStrategy	Branching strategy specifies: (1) how to select a candidate set of branching objects (2) how to compare two branching objects
CBcpsConstraint
CBcpsConstraintPool
CBcpsFieldListMod	This class contains modifications for a single `std::vector<T>` object
CBcpsMessage
CBcpsModel
CBcpsNodeDesc	For a given type, the objectVecStorage_ structure holds the description
CBcpsObject	A class for describing the objects that comprise a BCPS subproblem
CBcpsObjectListMod	Here is the set of `vectorMod_` objects that represent the list of objects of a particular type (either in relative or explicit form)
CBcpsObjectPool	Object pool is used to store objects
CBcpsSolution	This class holds the solution objects
CBcpsSubTree	This class is the data structure for storing a subtree within BCPS
CBcpsTreeNode	This class contain the data for a BCPS search tree node
CBcpsVariable
CBcpsVariablePool
