@ThreadSafe
@Immutable
public final class BooleanAttributeConverter
extends Object
implements AttributeConverter<Boolean>, PrimitiveConverter<Boolean>
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. AtomicBooleanAttributeConverter
).
This can be created via create()
.

transformFrom
Description copied from interface:AttributeConverter
Convert the provided Java object into anAttributeValue
. This will raise aRuntimeException
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());
