wrapped
be the underlying generator. Then, for or a given level l
, this.getByLevel(l)
will return a quadrature formula representing the difference between wrapped.getByLevel(l)
minus wrapped.getByLevel(l-1)
. In the special case of l
equals 0, wrapped.getByLevel(0)
is returned. The DeltaWrapper
generator supports only the getByLevel
method, as the getByNodes
method does not make sense for delta integration.
According to general Generator
contract, this class is thread-safe.
