Class BigIntegerAttributeConverter

java.lang.Object

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

All Implemented Interfaces:

AttributeConverter<BigInteger>

@ThreadSafe
@Immutable
public final class BigIntegerAttributeConverter
extends Object
implements AttributeConverter<BigInteger>

A converter between BigInteger and AttributeValue.

This stores values in DynamoDB as a number.

This supports reading the full range of integers supported by DynamoDB. For smaller numbers, consider using ShortAttributeConverter, IntegerAttributeConverter or LongAttributeConverter.

This does not support reading decimal numbers. For decimal numbers, consider using FloatAttributeConverter, DoubleAttributeConverter or BigDecimalAttributeConverter. Decimal numbers will cause a NumberFormatException on conversion.

This can be created via create().

Method Details

create

public static BigIntegerAttributeConverter create()

type

public EnhancedType<BigInteger> type()

Description copied from interface: AttributeConverter

The type supported by this converter.

Specified by:

type in interface AttributeConverter<BigInteger>

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<BigInteger>

transformFrom

public AttributeValue transformFrom(BigInteger 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<BigInteger>

transformTo

public BigInteger 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);
