  - v1_without_linearizable_reads_or_rejected_writes
```
public static final Config.PaxosVariant v1_without_linearizable_reads_or_rejected_writes
```
    v1 Paxos lacks most optimisations. Expect 4RTs for a write and 2RTs for a read. With legacy semantics for read/read and rejected write linearizability, i.e. not guaranteed.
  - v1
```
public static final Config.PaxosVariant v1
```
    v1 Paxos lacks most optimisations. Expect 4RTs for a write and 3RTs for a read.
  - v2_without_linearizable_reads
```
public static final Config.PaxosVariant v2_without_linearizable_reads
```
    v2 Paxos. With PaxosStatePurging.repaired safe to use ANY Commit consistency. Expect 2RTs for a write and 1RT for a read. With legacy semantics for read/read linearizability, i.e. not guaranteed.
  - v2_without_linearizable_reads_or_rejected_writes
```
public static final Config.PaxosVariant v2_without_linearizable_reads_or_rejected_writes
```
    v2 Paxos. With PaxosStatePurging.repaired safe to use ANY Commit consistency. Expect 2RTs for a write and 1RT for a read. With legacy semantics for read/read and rejected write linearizability, i.e. not guaranteed.
  - v2
```
public static final Config.PaxosVariant v2
```
    v2 Paxos. With PaxosStatePurging.repaired safe to use ANY Commit consistency. Expect 2RTs for a write, and either 1RT or 2RT for a read.

```
public static Config.PaxosVariant[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (Config.PaxosVariant c : Config.PaxosVariant.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Config.PaxosVariant valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
