Class AtomicBooleanAttributeConverter

java.lang.Object

software.amazon.awssdk.enhanced.dynamodb.internal.converter.attribute.AtomicBooleanAttributeConverter

All Implemented Interfaces:

AttributeConverter<AtomicBoolean>

@ThreadSafe
 @Immutable
public final class AtomicBooleanAttributeConverter
extends Object
implements AttributeConverter<AtomicBoolean>

A converter between AtomicBoolean and AttributeValue.

This stores values in DynamoDB as a boolean.

This supports reading every boolean value supported by DynamoDB, making it fully compatible with custom converters as well as internal converters (e.g. BooleanAttributeConverter).

This can be created via create().

Method Summary

Method Detail

type

public EnhancedType<AtomicBoolean> type()

Description copied from interface: AttributeConverter

The type supported by this converter.

Specified by:

type in interface AttributeConverter<AtomicBoolean>

attributeValueType

public AttributeValueType attributeValueType()

Description copied from interface: AttributeConverter

The AttributeValueType that a converter stores and reads values from DynamoDB via the AttributeValue class.

Specified by:

attributeValueType in interface AttributeConverter<AtomicBoolean>

create

public static AtomicBooleanAttributeConverter create()

transformFrom

public AttributeValue transformFrom(AtomicBoolean input)

Description copied from interface: AttributeConverter

Convert the provided Java object into an AttributeValue. This will raise a RuntimeException if the conversion fails, or the input is null.

Example:

 
 InstantAsStringAttributeConverter converter = InstantAsStringAttributeConverter.create();
 assertEquals(converter.transformFrom(Instant.EPOCH),
              EnhancedAttributeValue.fromString("1970-01-01T00:00:00Z").toAttributeValue());
 
 

Specified by:

transformFrom in interface AttributeConverter<AtomicBoolean>

transformTo

public AtomicBoolean transformTo(AttributeValue input)

Description copied from interface: AttributeConverter

Convert the provided AttributeValue into a Java object. This will raise a RuntimeException if the conversion fails, or the input is null.

 Example:
 
 InstantAsStringAttributeConverter converter = InstantAsStringAttributeConverter.create();
 assertEquals(converter.transformTo(EnhancedAttributeValue.fromString("1970-01-01T00:00:00Z").toAttributeValue()),
              Instant.EPOCH);
