Field Detail

DISABLE_CERT_CHECKING_SYSTEM_PROPERTY

public static final java.lang.String DISABLE_CERT_CHECKING_SYSTEM_PROPERTY

Disable validation of server certificates when using the HTTPS protocol. This should ONLY be used to do quick smoke tests against endpoints which don't yet have valid certificates; it should NEVER be used in production.

DEFAULT_METRICS_SYSTEM_PROPERTY

public static final java.lang.String DEFAULT_METRICS_SYSTEM_PROPERTY

System property used when starting up the JVM to enable the default metrics collected by the AWS SDK, which uploads the derived statistics to Amazon CloudWatch.

 Example:
  -Dcom.amazonaws.sdk.enableDefaultMetrics

EC2_METADATA_SERVICE_OVERRIDE_SYSTEM_PROPERTY

public static final java.lang.String EC2_METADATA_SERVICE_OVERRIDE_SYSTEM_PROPERTY

System property for overriding the Amazon EC2 Instance Metadata Service endpoint.

Constant Field Values

REGIONS_FILE_OVERRIDE_SYSTEM_PROPERTY

@Deprecated
public static final java.lang.String REGIONS_FILE_OVERRIDE_SYSTEM_PROPERTY

Deprecated. The SDK no longer supports a regions.xml override

Path to an override file for the region metadata loaded by the SDK that maps service/region pairs to endpoints and vice versa.

See Also:

Constant Field Values

DISABLE_REMOTE_REGIONS_FILE_SYSTEM_PROPERTY

public static final java.lang.String DISABLE_REMOTE_REGIONS_FILE_SYSTEM_PROPERTY

By default, the SDK will attempt to download an up-to-date set of region metadata from Amazon CloudFront when first required. This allows you to look up information about new regions and services without having to download a new version of the SDK every time.

If the SDK cannot download region metadata from Amazon CloudFront, it will fall back to loading the region metadata bundled with the SDK when it was released, which may be out of date.

Setting this system property to anything other than null will disable this remote fetching, and will only load region metadata that was bundled with the SDK. This gives you control over when new region metadata will be picked up by your application, and isolates you from potential issues if your application depends on being able to load metadata about a region which is not included in your version of the SDK and therefore may not be available in the event of network outages.

See Also:

Constant Field Values

DEFAULT_S3_STREAM_BUFFER_SIZE

public static final java.lang.String DEFAULT_S3_STREAM_BUFFER_SIZE

The default size of the buffer when uploading data from a stream. A buffer of this size will be created and filled with the first bytes from a stream being uploaded so that any transmit errors that occur in that section of the data can be automatically retried without the caller's intervention.

If not set, the default value of 128 KB will be used.

Method Detail

setGlobalTimeOffset

public static void setGlobalTimeOffset(int timeOffset)

Sets the global time offset. If this value is set then all the subsequent requests will use this value to generate timestamps. To adjust clock skew per request use Request.setTimeOffset(int)

Parameters:

timeOffset - the time difference between local client and server

getGlobalTimeOffset

public static int getGlobalTimeOffset()

Gets the global time offset. See Request.getTimeOffset() if global time offset is not set.

Returns:

GLOBAL_TIME_OFFSET an AtomicInteger that holds the value of time offset
