Methods
-
derive(
String toVar) → Expression -
Derives this expression with respect to the given variable.
inherited
-
evaluate(
EvaluationType type, ContextModel context) → dynamic -
Evaluates this expression according to given type and context.
inherited
-
getParam(
int i) → Variable - Returns the i-th parameter of this function (0-based).
-
getParamByName(
String name) → Variable - Returns the parameter with the given name.
-
noSuchMethod(
Invocation invocation) → dynamic -

inherited
-
simplify(
) → Expression -
Returns a simplified version of this expression.
Subclasses should overwrite this method, if applicable.
inherited
-
toFullString(
) → String - Returns the full string representation of this function. This could include the name, variables and expression.
-
toString(
) → String -
