@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()
```
    For responses, this returns true if the service returned a value for the Configurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - 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.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasConfigurations() method.
    
    Returns:
    
    A list of additional configurations to apply within a configuration object.
  - hasProperties
```
public final boolean hasProperties()
```
    For responses, this returns true if the service returned a value for the Properties property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - 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.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasProperties() method.
    
    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.
