Class DefaultAttributeConverterProvider

java.lang.Object

software.amazon.awssdk.enhanced.dynamodb.DefaultAttributeConverterProvider

All Implemented Interfaces:

AttributeConverterProvider

@SdkPublicApi
@ThreadSafe
@Immutable
public final class DefaultAttributeConverterProvider
extends Object
implements AttributeConverterProvider

This class is the default attribute converter provider in the DDB Enhanced library. When instantiated using the constructor DefaultAttributeConverterProvider() or the create() method, it's loaded with the currently supported attribute converters in the library.

Given an input, the method converterFor(EnhancedType) will identify a converter that can convert the specific Java type and invoke it. If a converter cannot be found, it will invoke a "parent" converter, which would be expected to be able to convert the value (or throw an exception).
