The base class for the Spanner library transaction rerun policies.
The Client::Commit() functions (there are several overloads) consume a callable to create mutations or a list of mutations. Commit() creates a transaction and applies the mutations. If the transaction fails, an instance of this class is used to control whether the transaction will be attempted again.
Functions
clone() const
Creates a new instance of the policy, reset to the initial state.
