Detailed Description

A cache for make_QuadRule()

This class has one important method: QuadRuleCache::Get() which returns the same result as make_QuadRule() but uses caching to construct the QuadRule only the first time.

Member Function Documentation

Get()

const QuadRule & lf::quad::QuadRuleCache::Get	(	base::RefEl	ref_el,
		unsigned	degree ) const

Retrieve a quadrature rule for reference element ref_el with degree d. Is identical to calling make_QuadRule().

Parameters

ref_el	The reference element for which the quadrature rule is.
degree	The degree of the quadrature rule

Returns

A quadrature rule for reference element ref_el with degree d.

Note

It is guaranteed that the returned reference will remain valid for the entire lifetime of the QuadRuleCache.
