All Implemented Interfaces:

NumeralFormulaManager<ParamFormulaType,ResultFormulaType>

public abstract class AbstractNumeralFormulaManager<TFormulaInfo,TType,TEnv,ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>
extends Object
implements NumeralFormulaManager<ParamFormulaType,ResultFormulaType>

Similar to the other Abstract*FormulaManager classes in this package, this class serves as a helper for implementing NumeralFormulaManager. It handles all the unwrapping and wrapping from Formula instances to solver-specific formula representations, such that the concrete class needs to handle only its own internal types.
