- All Implemented Interfaces:
AttributeConverter<Integer>
,PrimitiveConverter<Integer>
@ThreadSafe
@Immutable
public final class IntegerAttributeConverter
extends Object
implements AttributeConverter<Integer>, PrimitiveConverter<Integer>
A converter between
Integer
and AttributeValue
.
This stores values in DynamoDB as a number.
This supports reading numbers between Integer.MIN_VALUE
and Integer.MAX_VALUE
from DynamoDB. For smaller
numbers, consider using ShortAttributeConverter
. For larger numbers, consider using LongAttributeConverter
or BigIntegerAttributeConverter
. Numbers outside of the supported range will cause a NumberFormatException
on conversion.
This does not support reading decimal numbers. For decimal numbers, consider using FloatAttributeConverter
,
DoubleAttributeConverter
or BigDecimalAttributeConverter
. Decimal numbers will cause a
NumberFormatException
on conversion.

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());
