SparseArraySeed objects
SparseArraySeed-class.RdWARNING: SparseArraySeed objects are defunct in BioC >= 3.21!
SparseArraySeed objects were used internally to support block processing of sparse array-like objects in Bioconductor < 3.20. In Bioconductor 3.20, they were replaced with SparseArray objects from the SparseArray package.
