startingPosition

public EventSourcePosition startingPosition()

The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK Streams sources. AT_TIMESTAMP is only supported for Amazon Kinesis streams.

If the service returns an enum value that is not available in the current SDK version, startingPosition will return EventSourcePosition.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from startingPositionAsString().

Returns:

The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK Streams sources. AT_TIMESTAMP is only supported for Amazon Kinesis streams.

EventSourcePosition

startingPositionTimestamp

public Instant startingPositionTimestamp()

With StartingPosition set to AT_TIMESTAMP, the time from which to start reading.

toBuilder

public CreateEventSourceMappingRequest.Builder toBuilder()

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<CreateEventSourceMappingRequest.Builder,CreateEventSourceMappingRequest>

Specified by:

toBuilder in class LambdaRequest

Returns:

a builder for type T

builder

public static CreateEventSourceMappingRequest.Builder builder()

serializableBuilderClass

public static Class<? extends CreateEventSourceMappingRequest.Builder> serializableBuilderClass()

hashCode

public int hashCode()

Overrides:

hashCode in class AwsRequest

equals

public boolean equals(Object obj)

Overrides:

equals in class AwsRequest

equalsBySdkFields

public boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

toString

public String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public <T> Optional<T> getValueForField(String fieldName,
                                        Class<T> clazz)

Description copied from class: SdkRequest

Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.

Overrides:

getValueForField in class SdkRequest

Parameters:

fieldName - The name of the member to be retrieved.

clazz - The class to cast the returned object to.

Returns:

Optional containing the casted return value

sdkFields

public List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
