  - builder
```
public static Policies.Builder builder()
```
    Returns a builder to create a new Policies object.
    
    Returns:
    
    the builder.
  - defaultLoadBalancingPolicy
```
public static LoadBalancingPolicy defaultLoadBalancingPolicy()
```
    The default load balancing policy.
    The default load balancing policy is DCAwareRoundRobinPolicy with token awareness (so new TokenAwarePolicy(new DCAwareRoundRobinPolicy())).
    Note that this policy shuffles the replicas when token awareness is used, see TokenAwarePolicy(LoadBalancingPolicy, boolean) for an explanation of the tradeoffs.
    
    Returns:
    
    the default load balancing policy.
  - defaultReconnectionPolicy
```
public static ReconnectionPolicy defaultReconnectionPolicy()
```
    The default reconnection policy.
    The default reconnection policy is an ExponentialReconnectionPolicy where the base delay is 1 second and the max delay is 10 minutes;
    
    Returns:
    
    the default reconnection policy.
  - defaultRetryPolicy
```
public static RetryPolicy defaultRetryPolicy()
```
    The default retry policy.
    The default retry policy is DefaultRetryPolicy.
    
    Returns:
    
    the default retry policy.
  - defaultAddressTranslator
```
public static AddressTranslator defaultAddressTranslator()
```
    The default address translator.
    The default address translator is IdentityTranslator.
    
    Returns:
    
    the default address translator.
  - defaultTimestampGenerator
```
public static TimestampGenerator defaultTimestampGenerator()
```
    The default timestamp generator.
    This is an instance of AtomicMonotonicTimestampGenerator.
    
    Returns:
    
    the default timestamp generator.
  - defaultSpeculativeExecutionPolicy
```
public static SpeculativeExecutionPolicy defaultSpeculativeExecutionPolicy()
```
    The default speculative retry policy.
    The default speculative retry policy is a NoSpeculativeExecutionPolicy.
    
    Returns:
    
    the default speculative retry policy.
  - defaultEndPointFactory
```
public static EndPointFactory defaultEndPointFactory()
```
  - getLoadBalancingPolicy
```
public LoadBalancingPolicy getLoadBalancingPolicy()
```
    The load balancing policy in use.
    The load balancing policy defines how Cassandra hosts are picked for queries.
    
    Returns:
    
    the load balancing policy in use.
  - getReconnectionPolicy
```
public ReconnectionPolicy getReconnectionPolicy()
```
    The reconnection policy in use.
    The reconnection policy defines how often the driver tries to reconnect to a dead node.
    
    Returns:
    
    the reconnection policy in use.
  - getRetryPolicy
```
public RetryPolicy getRetryPolicy()
```
    The retry policy in use.
    The retry policy defines in which conditions a query should be automatically retries by the driver.
    
    Returns:
    
    the retry policy in use.
  - getAddressTranslator
```
public AddressTranslator getAddressTranslator()
```
    The address translator in use.
    
    Returns:
    
    the address translator in use.
  - getTimestampGenerator
```
public TimestampGenerator getTimestampGenerator()
```
    The timestamp generator to use.
    
    Returns:
    
    the timestamp generator to use.
  - getSpeculativeExecutionPolicy
```
public SpeculativeExecutionPolicy getSpeculativeExecutionPolicy()
```
    The speculative execution policy in use.
    
    Returns:
    
    the speculative execution policy in use.
  - getEndPointFactory
```
public EndPointFactory getEndPointFactory()
```
