Method Details

getKey

@Stability(Stable)
@NotNull
Map<String,DynamoAttributeValue> getKey()

Primary key of the item to retrieve.

For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

getTable

@Stability(Stable)
@NotNull
ITable getTable()

The name of the table containing the requested item.

getConsistentRead

@Stability(Stable)
@Nullable
default Boolean getConsistentRead()

Determines the read consistency model: If set to true, then the operation uses strongly consistent reads;

otherwise, the operation uses eventually consistent reads.

Default: false

getExpressionAttributeNames

@Stability(Stable)
@Nullable
default Map<String,String> getExpressionAttributeNames()

One or more substitution tokens for attribute names in an expression.

Default: - No expression attributes

getProjectionExpression

@Stability(Stable)
@Nullable
default List<DynamoProjectionExpression> getProjectionExpression()

An array of DynamoProjectionExpression that identifies one or more attributes to retrieve from the table.

These attributes can include scalars, sets, or elements of a JSON document.

Default: - No projection expression

See Also:

• https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_GetItem.html#DDB-GetItem-request-ProjectionExpression

getReturnConsumedCapacity

@Stability(Stable)
@Nullable
default DynamoConsumedCapacity getReturnConsumedCapacity()

Determines the level of detail about provisioned throughput consumption that is returned in the response.

Default: DynamoConsumedCapacity.NONE

• https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_GetItem.html#DDB-GetItem-request-ReturnConsumedCapacity

builder

@Stability(Stable)
static DynamoGetItemProps.Builder builder()

Returns:

a DynamoGetItemProps.Builder of DynamoGetItemProps
