Class LocalTimeAttributeConverter

java.lang.Object

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

All Implemented Interfaces:

AttributeConverter<LocalTime>

@ThreadSafe
@Immutable
public final class LocalTimeAttributeConverter
extends Object
implements AttributeConverter<LocalTime>

A converter between LocalTime and AttributeValue.

This stores and reads values in DynamoDB as a String.

LocalTimes are stored in the official LocalTime format "HH:II:SS[.NNNNNNNNN]", where:

1. H is a 2-character, zero-prefixed hour between 00 and 23
2. I is a 2-character, zero-prefixed minute between 00 and 59
3. S is a 2-character, zero-prefixed second between 00 and 59
4. N is a 9-character, zero-prefixed nanosecond between 000,000,000 and 999,999,999. The . and N may be excluded if N is 0.

See LocalTime for more details on the serialization format.

This serialization is lexicographically orderable.

Examples:

• LocalTime.of(5, 30, 0) is stored as an AttributeValue with the String "05:30"
• LocalTime.of(5, 30, 0, 1) is stored as an AttributeValue with the String "05:30:00.000000001"

This can be created via create().

Method Details

create

public static LocalTimeAttributeConverter create()

type

public EnhancedType<LocalTime> type()

Description copied from interface: AttributeConverter

The type supported by this converter.

Specified by:

type in interface AttributeConverter<LocalTime>

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<LocalTime>

transformFrom

public AttributeValue transformFrom(LocalTime 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<LocalTime>

transformTo

public LocalTime 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);
 
 

Specified by:

transformTo in interface AttributeConverter<LocalTime>
