+# BufferedStream
+
+## Abstract:
+
+One type that has to satisfy a BufferedStream operator and type.
+
+## Rationale:
+
+- HPC systems.
+- I/O systems.
+- HFT systems.
+
+## Example:
+
+```cpp
+BStream<BOperator, BType>;
+```
+
+BOperator must not flush at all times, but have the option to.

+## Abstract:
+
+One type that has to satisfy an unbuffered Stream operator and type.

+## Rationale:

+- Fast and direct-flush operations.
+- High-Throughput systems.

+UBStream<UBOperator, UBType>;

+
+UBOperator must flush at all times!
