returns a GeneralExpression after replacement of NamedUnknowns by an associated expression and after values computation. More... | |
Handle< Expr_GeneralExpression > | ShallowSimplified () const override |
Returns a GeneralExpression after a simplification of the arguments of <me>. More... | |
Handle< Expr_GeneralExpression > | Copy () const override |
Returns a copy of <me> having the same unknowns and functions. More... | |
Standard_Boolean | ContainsUnknowns () const override |
Tests if <me> contains NamedUnknown. (returns always False) More... | |
Standard_Boolean | Contains (const Handle< Expr_GeneralExpression > &exp) const override |
Tests if <exp> is contained in <me>. More... | |

Public Member Functions inherited from Expr_NamedExpression | |
const TCollection_AsciiString & | GetName () const |
void | SetName (const TCollection_AsciiString &name) |
virtual Standard_Boolean | IsShareable () const override |
Tests if <me> can be shared by one or more expressions or must be copied. This method redefines to a True value the GeneralExpression method. More... | |
Standard_Boolean | IsIdentical (const Handle< Expr_GeneralExpression > &Other) const override |
Tests if <me> and <Other> define the same expression. This method does not include any simplification before testing. More... | |

returns a string representing <me> in a readable way. More... | |
Public Member Functions inherited from Expr_GeneralExpression | |
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... | |
Public Member Functions inherited from Standard_Transient | |
Standard_Transient () | |
Empty constructor. More... | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. More... | |
Standard_Transient & | operator= (const Standard_Transient &) |
Assignment operator, needed to avoid copying reference counter. More... | |
virtual | ~Standard_Transient () |
Destructor must be virtual. More... | |
virtual void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |

Standard_Boolean | IsKind (const opencascade::handle< Standard_Type > &theType) const |

Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
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... | |
