S3Config (object-client 3.4.6 API)

java.lang.Object
- com.emc.object.ObjectConfig<S3Config>
- - com.emc.object.s3.S3Config

```
public class S3Config
extends ObjectConfig<S3Config>
```
To enable the smart-client with a single VDC, use the S3Config(Protocol, String...) constructor:
```
     S3Config s3Config = new S3Config(Protocol.HTTP, "10.10.10.11", "10.10.10.12");
 
```
To enable the smart-client with multiple VDCs, use the S3Config(Protocol, Vdc...) constructor:
```
     S3Config s3Config = new S3Config(Protocol.HTTP, new Vdc("10.10.10.11", "10.10.10.12"), new Vdc("10.20.10.11", "10.20.10.12"));
 
```
To use an external load balancer without virtual-host-style requests use the S3Config(URI) constructor:
```
     S3Config s3Config = new S3Config("https://10.10.10.10:8443");
 
```
To use an external load balancer with virtual-host-style requests (where bucket.namespace. is prepended to the hostname), use the S3Config(URI) constructor and setUseVHost(boolean) to true:
```
     S3Config s3Config = new S3Config("https://s3.company.com").withUseVHost(true);
 
```
NOTE: If you enable virtual-host-style requests, you must specify your namespace or set it to null and include it in the hostname of the endpoint.

    Empty constructor for internal use only!
  - S3Config
```
public S3Config(java.net.URI endpoint)
```
    External load balancer constructor (no smart-client).
    NOTE: To use virtual-host-style requests where bucket.namespace. is prepended to the host, you must setUseVHost(boolean) to true.
  - S3Config
```
public S3Config(Protocol protocol,
                java.lang.String... hostList)
```
    Single VDC smart-client constructor.
  - S3Config
```
public S3Config(Protocol protocol,
                com.emc.rest.smart.ecs.Vdc... vdcs)

  - isUseVHost
```
public boolean isUseVHost()
```
  - setUseVHost
```
public void setUseVHost(boolean useVHost)
```
    Set to true to enable virtual-host-style requests. This prepends namespaces and buckets as appropriate for each request.
    NOTE: To use virtual host configuration, you must disable the smart client by using the S3Config(URI) constructor. You must also specify your namespace or set it to null and include it in the hostname of the endpoint.
  - isSignNamespace
```
public boolean isSignNamespace()
```
  - setSignNamespace
```
public void setSignNamespace(boolean signNamespace)
```
    Standard ECS configurations require signing the namespace to support cross-namespace requests. To change this behavior to a legacy type virtual host, which is isolated to the default namespace of the user, set this to false.
  - isChecksumEnabled
```
public boolean isChecksumEnabled()
```
  - setChecksumEnabled
```
public void setChecksumEnabled(boolean checksumEnabled)
```
    By default, MD5 sums are verified on whole-object reads and writes whenever possible. You can disable that by setting this to false.
  - isRetryEnabled
```
public boolean isRetryEnabled()
```
  - setRetryEnabled
```
public void setRetryEnabled(boolean retryEnabled)
```
    Set to false to disable automatic retry of (retriable) requests (default is true)
  - getInitialRetryDelay
```
public int getInitialRetryDelay()
```
  - setInitialRetryDelay
```
public void setInitialRetryDelay(int initialRetryDelay)
```
    number of milliseconds to delay before the first retry attempt after a failed request. The delay time increases by a factor of 2 after each failed request
  - getRetryLimit
```
public int getRetryLimit()
```
  - setRetryLimit
```
public void setRetryLimit(int retryLimit)
```
    Sets the maximum number of automatic retries of failed (retriable) requests. Default is 3 retries (maximum 4 total requests)
  - getRetryBufferSize
```
public int getRetryBufferSize()
```
  - setRetryBufferSize
```
public void setRetryBufferSize(int retryBufferSize)
```
    Allocates a stream buffer to use for retries. Requests that fail before sending this much data will be retried using data from the buffer. Default buffer is 2MB
  - getFaultInjectionRate
```
public float getFaultInjectionRate()
```
  - setFaultInjectionRate
```
public void setFaultInjectionRate(float faultInjectionRate)
```
    Sets the fault injection rate. Enables fault injection when this number is > 0. The rate is a ratio expressed as a decimal between 0 and 1. This is the rate at which faults (HTTP 500 errors) should randomly be injected into the response. When faults are injected, the real request is never sent over the wire. Fault injection is disabled by default.
  - isSignMetadataSearch
```
public boolean isSignMetadataSearch()
```
  - setSignMetadataSearch
```
public void setSignMetadataSearch(boolean signMetadataSearch)
```
    Instructs the client whether to sign the metadata search parameters. Prior to ECS 3.0, these were not signed, but as of 3.0 they are now signed. Be sure to set this appropriately based on your ECS software version.
    Note: as of object-client 3.0, this defaults to true (MD search params will be signed)
  - isUseV2Signer
```
public boolean isUseV2Signer()
```
  - setUseV2Signer
```
public void setUseV2Signer(boolean useV2Signer)
```
    Sets the AWS signature version for authentication requests, default is v2, set this to false to use v4.
