Detailed Description

This base class represents a vector function $F: \mathbf{R}^D \rightarrow \mathbf{R}^D$.

Constructor & Destructor Documentation

◆ VectorFunction() [1/3]

VectorFunction::VectorFunction ( bool  a_homogeneous,
bool  a_constant 
)

Base class constructor. Must be called by subclasses.

Parameters
a_homogeneousThis flag indicates whether the vector function is constant in space.
a_constantThis flag indicates whether the vector function is constant in time.

◆ ~VectorFunction()

virtual VectorFunction::~VectorFunction ( )
virtual

Destructor.

◆ VectorFunction() [2/3]

VectorFunction::VectorFunction ( )
private

◆ VectorFunction() [3/3]

VectorFunction::VectorFunction ( const VectorFunction &  )
private

Member Function Documentation

◆ operator()() [1/2]

virtual RealVect VectorFunction::operator() ( const RealVect &  a_x,
Real  a_t 
) const
pure virtual

Override this method to evaluate this function at the given point in space and time.

Parameters
a_xA point in $D$-dimensional space.
a_tThe time at which the function is evaluated.

Implemented in ConstantVectorFunction.

Referenced by operator()().

◆ derivative() [1/2]

virtual RealVect VectorFunction::derivative ( const IntVect &  a_order,
const RealVect &  a_x,
Real  a_t 
) const
virtual

Override this method to evaluate the given partial derivative of the function at the given point in space and time.

Parameters
a_orderA multi-index identifying the order(s) of the partial derivative of the function to be evaluated.
a_xA point in $D$-dimensional space.
a_tThe time at which the derivative is to be evaluated.

Reimplemented in ConstantVectorFunction.

Referenced by derivative().

◆ hasDerivative()

virtual bool VectorFunction::hasDerivative ( const IntVect &  a_order) const
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.

Parameters
a_orderA multi-index identifying the order(s) of the desired partial derivative of the function.

◆ operator()() [2/2]

RealVect VectorFunction::operator() ( const RealVect &  a_x) const
inline

This evaluates the function at time 0.

Parameters
a_xA point in $D$-dimensional space.

References operator()().

◆ derivative() [2/2]

RealVect VectorFunction::derivative ( const IntVect &  a_order,
const RealVect &  a_x 
) const
inline

This evaluates the given partial derivative of the function at time 0.

Parameters
a_orderA multi-index identifying the order(s) of the partial derivative of the function to be evaluated.
a_xA point in $D$-dimensional space.

◆ isHomogeneous()

bool VectorFunction::isHomogeneous ( ) const
inline

Returns true if this function is homogeneous, false otherwise.

References m_isHomogeneous.

◆ isConstant()

bool VectorFunction::isConstant ( ) const
inline

Returns true if this function is constant, false otherwise.

References m_isConstant.

◆ operator=()

VectorFunction& VectorFunction::operator= ( const VectorFunction &  )
private
