Class Summary

Class	Description
AwsHostNameUtils
AWSRequestMetrics	Used as both a base class and a minimal support of AWS SDK request metrics.
AWSRequestMetricsFullSupport	In contrast to AWSRequestMetrics, which is intended to be a minimal support of AWS SDK request metrics, this class is the full support of AWS SDK request metrics including features such as properties and sub-events.
BinaryUtils	Utilities for encoding and decoding binary data to and from different forms.
CapacityManager	Manages capacity of a finite resource.
CollectionUtils
ComparableUtils
CountingInputStream	Simple input stream wrapper utility to count the bytes read from a stream.
CRC32ChecksumCalculatingInputStream	Simple InputStream wrapper that examines the wrapped stream's contents as they are read and calculates and CRC32 checksum.
CredentialUtils
DateUtils	Utilities for parsing and formatting dates.
EC2MetadataUtils	Utility class for retrieving Amazon EC2 instance metadata. You can use the data to build more generic AMIs that can be modified by configuration files supplied at launch time.
EC2MetadataUtils.IAMInfo	Information about the last time the instance profile was updated, including the instance's LastUpdated date, InstanceProfileArn, and InstanceProfileId.
EC2MetadataUtils.IAMSecurityCredential	The temporary security credentials (AccessKeyId, SecretAccessKey, SessionToken, and Expiration) associated with the IAM role.
EC2MetadataUtils.InstanceInfo	This POJO is a best attempt to capture the instance info which is only guaranteed to be a JSON document per http://docs.aws.amazon.com/AWSEC2/latest /UserGuide/ec2-instance-metadata.html Instance info includes dynamic information about the current instance such as region, instanceId, private IP address, etc.
EC2MetadataUtils.NetworkInterface	All of the metadata associated with a network interface on the instance.
HostnameValidator
IdempotentUtils	Utility class to manage idempotency token
ImmutableMapParameter<K,V>	An immutable map that could be built by convenient constructors.
ImmutableMapParameter.Builder<K,V>	A convenient builder for creating ImmutableMapParameter instances.
JavaVersionParser
JavaVersionParser.JavaVersion	Struct like class representing a specific version of Java.
LengthCheckInputStream	Used to perform length check to ensure the number of bytes read from the underlying input stream is the same as the expected total.
Md5Utils	Utility methods for computing MD5 sums.
NamedDefaultThreadFactory	An implementation of ThreadFactory that is based off of the default implementation in the java libraries except that it inserts a custom name instead of a pool number.
NullResponseMetadataCache	No-op response metadata cache used when a client instance is configured without response metadata caching enabled.
NumberUtils
Platform
PolicyUtils	Utility methods related to IAM policies
ReflectionMethodInvoker<T,R>	This class acts as a proxy to invoke a specific method on objects of a specific class.
ResponseMetadataCache	Cache of response metadata for recently executed requests for diagnostic purposes.
RuntimeHttpUtils
SdkHttpUtils
ServiceClientHolderInputStream	This wrapper input stream holds a reference to the service client.
StringInputStream	Simple wrapper for ByteArrayInputStream that will automatically encode the string as UTF-8 data, and still allows access to the original string.
StringMapBuilder	A convenient map builder for Strings.
StringUtils	Utilities for converting objects to strings.
TimingInfo	Used both as a base class and a minimal support of timing info.
UnreliableFilterInputStream	An internal class used solely for the purpose of testing via failure injection.
UriResourcePathUtils
ValidationUtils	Useful utilities to validate dependencies
VersionInfoUtils	Utility class for accessing AWS SDK versioning information.
XmlUtils
XMLWriter	Utility for creating easily creating XML documents, one element at a time.
XpathUtils	Utility methods for extracting data from XML documents using Xpath expressions.
