Inheritance diagram for Expr_GeneralExpression:
Public Member Functions | |
virtual Standard_EXPORT Standard_Integer | NbSubExpressions () const =0 |
Returns the number of sub-expressions contained in <me> ( >= 0) . | |
virtual Standard_EXPORT const Handle_Expr_GeneralExpression & | SubExpression (const Standard_Integer I) const =0 |
Returns the -th sub-expression of <me> raises OutOfRange if > NbSubExpressions(me) . | |
virtual Standard_EXPORT Handle_Expr_GeneralExpression | Simplified () const =0 |
Returns a GeneralExpression after replacement of NamedUnknowns by an associated expression and after values computation. . | |
virtual Standard_EXPORT Handle_Expr_GeneralExpression | ShallowSimplified () const =0 |
Returns a GeneralExpression after a simplification of the arguments of <me>. . | |
virtual Standard_EXPORT Handle_Expr_GeneralExpression | Copy () const =0 |
Returns a copy of <me> having the same unknowns and functions. . | |
virtual Standard_EXPORT Standard_Boolean | ContainsUnknowns () const =0 |
Tests if <me> contains NamedUnknowns. . | |
virtual Standard_EXPORT Standard_Boolean | Contains (const Handle(Expr_GeneralExpression)&exp) const =0 |
Tests if <exp> is contained in <me>. . | |
virtual Standard_EXPORT Standard_Boolean | IsLinear () const =0 |
Tests if <me> is linear on every NamedUnknown it contains. . | |
virtual Standard_EXPORT 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). . | |
virtual Standard_EXPORT 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. . | |
virtual Standard_EXPORT Handle_Expr_GeneralExpression | Derivative (const Handle(Expr_NamedUnknown)&X) const =0 |
Returns the derivative on <x> unknown of <me> . | |
virtual Standard_EXPORT 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 . | |
virtual Standard_EXPORT void | Replace (const Handle(Expr_NamedUnknown)&var, const Handle(Expr_GeneralExpression)&with)=0 |
Replaces all occurences of with copies of <with> in <me>. Copies of <with> are made with the Copy() method. Raises InvalidOperand if <with> contains <me>. . | |
virtual Standard_EXPORT 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. . | |
Standard_EXPORT 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. . | |
virtual Standard_EXPORT TCollection_AsciiString | String () const =0 |
returns a string representing <me> in a readable way. | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
