virtual |
Print mode-specific parameters.
Meant to be overloaded by subclasses to print more details about that mode. Is used by print() to print the mode_specific column.
| os | Stream to print to. |
Reimplemented from RecursiveParams.
|
inlinevirtual |
Get the size of each block in the database that the datastore will actually use.
This may be different than block_size() when tau-independence is used.
Reimplemented from PercyParams.
