@Generated(value="software.amazon.awssdk:codegen")
public final class Configuration
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Configuration.Builder,Configuration>

Amazon EMR releases 4.x or later.

An optional configuration specification to be used when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR. A configuration consists of a classification, properties, and optional nested configurations. A classification refers to an application-specific configuration file. Properties are the settings you want to change in that file. For more information, see Configuring Applications.

Method Detail

classification

public final String classification()

The classification within a configuration.

Returns:

The classification within a configuration.

hasConfigurations

public final boolean hasConfigurations()

Returns true if the Configurations property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

configurations

public final List<Configuration> configurations()

A list of additional configurations to apply within a configuration object.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasConfigurations() to see if a value was sent in this field.

Returns:

A list of additional configurations to apply within a configuration object.

hasProperties

public final boolean hasProperties()

Returns true if the Properties property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

properties

public final Map<String,String> properties()

A set of properties specified within a configuration classification.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasProperties() to see if a value was sent in this field.

Returns:

A set of properties specified within a configuration classification.

toBuilder

public Configuration.Builder toBuilder()

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<Configuration.Builder,Configuration>

Returns:

a builder for type T

builder

public static Configuration.Builder builder()

serializableBuilderClass

public static Class<? extends Configuration.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public final <T> Optional<T> getValueForField(String fieldName,
                                              Class<T> clazz)

sdkFields

public final List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
