 Public Member Functions inherited from Expr_GeneralExpression | |
| virtual Handle< Expr_GeneralExpression > | ShallowSimplified () const =0 |
| Returns a GeneralExpression after a simplification of the arguments of <me>. More... | |
| virtual Handle< Expr_GeneralExpression > | Copy () const =0 |
| Returns a copy of <me> having the same unknowns and functions. More... | |
| virtual Standard_Boolean | IsLinear () const =0 |
| 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... | |
