Tests if <me> is linear on every NamedUnknown it contains. More... | |
virtual Standard_Boolean | IsShareable () const |
Tests if <me> can be shared by one or more expressions or must be copied. This method returns False as a default value. To be redefined ( especially for NamedUnknown). More... | |
virtual Standard_Boolean | IsIdentical (const Handle< Expr_GeneralExpression > &Other) const =0 |
Tests if <me> and <Other> define the same expression. Warning: This method does not include any simplification before testing. It could also be very slow; to be used carefully. More... | |
virtual Handle< Expr_GeneralExpression > | Derivative (const Handle< Expr_NamedUnknown > &X) const =0 |
Returns the derivative on <X> unknown of <me> More... | |
virtual Handle< Expr_GeneralExpression > | NDerivative (const Handle< Expr_NamedUnknown > &X, const Standard_Integer N) const |
Returns the <N>-th derivative on <X> unknown of <me>. Raise OutOfRange if N <= 0. More... | |
virtual Standard_Real | Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &vals) const =0 |
Returns the value of <me> (as a Real) by replacement of <vars> by <vals>. Raises NotEvaluable if <me> contains NamedUnknown not in <vars> or NumericError if result cannot be computed. More... | |
Standard_Real | EvaluateNumeric () const |
Returns the value of <me> (as a Real) by replacement of <vars> by <vals>. Raises NotEvaluable if <me> contains NamedUnknown not in <vars> or NumericError if result cannot be computed. More... | |
virtual TCollection_AsciiString | String () const =0 |

Standard_Boolean | IsKind (const Standard_CString theTypeName) const |

Standard_Transient * | This () const |
Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More... | |

Get the reference counter of this object. More... | |
void | IncrementRefCounter () const |
Increments the reference counter of this object. More... | |
Standard_Integer | DecrementRefCounter () const |
Decrements the reference counter of this object; returns the decremented value. More... | |
