Class AwsDefaultClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

java.lang.Object

software.amazon.awssdk.core.client.builder.SdkDefaultClientBuilder<BuilderT,ClientT>

software.amazon.awssdk.awscore.client.builder.AwsDefaultClientBuilder<BuilderT,ClientT>

Type Parameters:

BuilderT - The type of builder, for chaining.

ClientT - The type of client generated by this builder.

All Implemented Interfaces:

AwsClientBuilder<BuilderT,ClientT>, SdkClientBuilder<BuilderT,ClientT>, Buildable, SdkBuilder<BuilderT,ClientT>

public abstract class AwsDefaultClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>
extends SdkDefaultClientBuilder<BuilderT,ClientT>
implements AwsClientBuilder<BuilderT,ClientT>

An SDK-internal implementation of the methods in AwsClientBuilder, AwsAsyncClientBuilder and AwsSyncClientBuilder. This implements all methods required by those interfaces, allowing service-specific builders to just implement the configuration they wish to add.

By implementing both the sync and async interface's methods, service-specific builders can share code between their sync and async variants without needing one to extend the other. Note: This only defines the methods in the sync and async builder interfaces. It does not implement the interfaces themselves. This is because the sync and async client builder interfaces both require a type-constrained parameter for use in fluent chaining, and a generic type parameter conflict is introduced into the class hierarchy by this interface extending the builder interfaces themselves.

Like all AwsClientBuilders, this class is not thread safe.

Constructor Detail

AwsDefaultClientBuilder

protected AwsDefaultClientBuilder()

Method Detail

serviceEndpointPrefix

protected abstract String serviceEndpointPrefix()

Implemented by child classes to define the endpoint prefix used when communicating with AWS. This constitutes the first part of the URL in the DNS name for the service. Eg. in the endpoint "dynamodb.amazonaws.com", this is the "dynamodb".

For standard services, this should match the "endpointPrefix" field in the AWS model.

signingName

protected abstract String signingName()

Implemented by child classes to define the signing-name that should be used when signing requests when communicating with AWS.

serviceName

protected abstract String serviceName()

Implemented by child classes to define the service name used to identify the request in things like metrics.

childHttpConfig

protected final AttributeMap childHttpConfig()

Overrides:

childHttpConfig in class SdkDefaultClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

serviceHttpConfig

protected AttributeMap serviceHttpConfig()

Optionally overridden by child classes to define service-specific HTTP configuration defaults.

mergeChildDefaults

protected final SdkClientConfiguration mergeChildDefaults(SdkClientConfiguration configuration)

Overrides:

mergeChildDefaults in class SdkDefaultClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

mergeServiceDefaults

protected SdkClientConfiguration mergeServiceDefaults(SdkClientConfiguration configuration)

Optionally overridden by child classes to define service-specific default configuration.

finalizeChildConfiguration

protected final SdkClientConfiguration finalizeChildConfiguration(SdkClientConfiguration configuration)

Overrides:

finalizeChildConfiguration in class SdkDefaultClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

finalizeServiceConfiguration

protected SdkClientConfiguration finalizeServiceConfiguration(SdkClientConfiguration configuration)

Optionally overridden by child classes to derive service-specific configuration from the default-applied configuration.

region

public final BuilderT region(Region region)

Description copied from interface: AwsClientBuilder

Configure the region with which the SDK should communicate.

If this is not specified, the SDK will attempt to identify the endpoint automatically using the following logic:

1. Check the 'aws.region' system property for the region.
2. Check the 'AWS_REGION' environment variable for the region.
3. Check the {user.home}/.aws/credentials and {user.home}/.aws/config files for the region.
4. If running in EC2, check the EC2 metadata service for the region.

Specified by:

region in interface AwsClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

setRegion

public final void setRegion(Region region)

credentialsProvider

public final BuilderT credentialsProvider(AwsCredentialsProvider credentialsProvider)

Description copied from interface: AwsClientBuilder

Configure the credentials that should be used to authenticate with AWS.

The default provider will attempt to identify the credentials automatically using the following checks:

1. Java System Properties - aws.accessKeyId and aws.secretKey
2. Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
3. Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI
4. Credentials delivered through the Amazon EC2 container service if AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable is set and security manager has permission to access the variable.
5. Instance profile credentials delivered through the Amazon EC2 metadata service

If the credentials are not found in any of the locations above, an exception will be thrown at SdkBuilder.build() time.

Specified by:

credentialsProvider in interface AwsClientBuilder<BuilderT extends AwsClientBuilder<BuilderT,ClientT>,ClientT>

setCredentialsProvider

public final void setCredentialsProvider(AwsCredentialsProvider credentialsProvider)
