ScalarFunction () | |
ScalarFunction (const ScalarFunction &) | |
ScalarFunction & | operator= (const ScalarFunction &) |
This base class represents a scalar function .
ScalarFunction::ScalarFunction | ( | bool | a_homogeneous, |
bool | a_constant | ||
) |
Base class constructor. Must be called by subclasses.
a_homogeneous | This flag indicates whether the scalar function is constant in space. |
a_constant | This flag indicates whether the scalar function is constant in time. |
|

private |
Override this method to evaluate this function at the given point in space and time.
a_x | A point in -dimensional space. |
a_t | The time at which the function is to be evaluated. |
Implemented in ConstantScalarFunction.
Referenced by operator()().
|
virtual |
Override this method to evaluate the given partial derivative of the function at the given point in space and time.
a_order | A multi-index identifying the order(s) of the partial derivative of the function to be evaluated. |
a_x | A point in -dimensional space. |
a_t | The time at which the derivative is to be evaluated. |
Reimplemented in ConstantScalarFunction.
Referenced by derivative().
|
virtual |
Override this method to return true if the derivative of the requested order exists and is available, false if it is not. This must be implemented in a way that is consistent with the derivative method.
a_order | A multi-index identifying the order(s) of the desired partial derivative of the function. |
This evaluates the function at time 0.
a_x | A point in -dimensional space. |
References operator()().
This evaluates the given partial derivative of the function at time 0.
a_order | A multi-index identifying the order(s) of the partial derivative of the function to be evaluated. |
a_x | A point in -dimensional space. |
