- * @brief  Erasure Code Isa CODEC Table Cache
- *
- * The INTEL ISA-L library supports two pre-defined encoding matrices (cauchy = default, reed_sol_van = default)
- * The default CODEC implementation using these two matrices is implemented in class ErasureCodeIsaDefault.
- * ISA-L allows to use custom matrices which might be added later as implementations deriving from the base class ErasoreCodeIsa.
