Class BigDecimalAttributeConverter
java.lang.Object
software.amazon.awssdk.enhanced.dynamodb.internal.converter.attribute.BigDecimalAttributeConverter
- All Implemented Interfaces:
AttributeConverter<BigDecimal>
@ThreadSafe
@Immutable
public final class BigDecimalAttributeConverter
extends Object
implements AttributeConverter<BigDecimal>
A converter between
BigDecimal
and AttributeValue
.
This stores values in DynamoDB as a number.
This supports perfect precision with the full range of numbers that can be stored in DynamoDB. For less precision or
smaller values, consider using FloatAttributeConverter
or DoubleAttributeConverter
.
If values are known to be whole numbers, it is recommended to use a perfect-precision whole number representation like those
provided by ShortAttributeConverter
, IntegerAttributeConverter
or BigIntegerAttributeConverter
.
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());
