virtual void mfem::SpacingFunction::GetIntParameters ( Array< int > &  p ) const

pure virtual

Returns the array of integer parameters defining the spacing function.

Parameters

[out]

p

Array of integer parameters, resized appropriately.

Implemented in mfem::UniformSpacingFunction, mfem::LinearSpacingFunction, mfem::GeometricSpacingFunction, mfem::BellSpacingFunction, mfem::GaussianSpacingFunction, mfem::LogarithmicSpacingFunction, and mfem::PiecewiseSpacingFunction.

Print()

virtual void mfem::SpacingFunction::Print ( std::ostream &  os ) const

pure virtual

Prints all the data necessary to define the spacing function and its current state (size and other parameters).

The format is generally SpacingType numIntParam numDoubleParam {int params} {double params}

Implemented in mfem::UniformSpacingFunction, mfem::LinearSpacingFunction, mfem::GeometricSpacingFunction, mfem::BellSpacingFunction, mfem::GaussianSpacingFunction, mfem::LogarithmicSpacingFunction, and mfem::PiecewiseSpacingFunction.

ScaleParameters()

virtual void mfem::SpacingFunction::ScaleParameters ( real_t  a )

inlinevirtual

Scales parameters by the factor a associated with Size().

Note that parameters may be scaled inversely during coarsening and refining, so the scaling should be linear in the sense that scaling by a number followed by scaling by its inverse has no effect on parameters.

Reimplemented in mfem::LinearSpacingFunction, mfem::GeometricSpacingFunction, mfem::BellSpacingFunction, mfem::GaussianSpacingFunction, and mfem::PiecewiseSpacingFunction.

Definition at line 68 of file spacing.hpp.

SetReverse()

inline

Sets the property that determines whether the spacing is reversed.

Definition at line 48 of file spacing.hpp.

SetSize()

virtual void mfem::SpacingFunction::SetSize ( int  size )

pure virtual

Sets the size, or number of intervals (elements).

Implemented in mfem::UniformSpacingFunction, mfem::LinearSpacingFunction, mfem::GeometricSpacingFunction, mfem::BellSpacingFunction, mfem::GaussianSpacingFunction, mfem::LogarithmicSpacingFunction, and mfem::PiecewiseSpacingFunction.
