クラス DynamoDBMapperConfig

com.amazonaws.services.dynamodb.datamodeling.DynamoDBMapperConfig

非推奨です。

@Deprecated
public class DynamoDBMapperConfig
extends java.lang.Object

Immutable configuration object for service call behavior. An instance of this configuration is supplied to every DynamoDBMapper at construction; if not provided explicitly, DEFAULT is used. New instances can be given to the mapper object on individual save, load, and delete operations to override the defaults. For example:

 DynamoDBMapper mapper = new DynamoDBMapper(dynamoDBClient);
 // Force this read to be consistent
 DomainClass obj = mapper.load(DomainClass.class, key, new DynamoDBMapperConfig(ConsistentReads.CONSISTENT));
 // Force this save operation to use putItem rather than updateItem
 mapper.save(obj, new DynamoDBMapperConfig(SaveBehavior.CLOBBER));
 // Save the object into a different table
 mapper.save(obj, new DynamoDBMapperConfig(new TableNameOverride("AnotherTable")));
 // Delete the object even if the version field is out of date
 mapper.delete(obj, new DynamoDBMapperConfig(SaveBehavior.CLOBBER));

public static final DynamoDBMapperConfig DEFAULT

非推奨です。

Default configuration uses UPDATE behavior for saves and EVENTUALly consistent reads, with no table name override.

コンストラクタの詳細

DynamoDBMapperConfig

public DynamoDBMapperConfig(DynamoDBMapperConfig.SaveBehavior saveBehavior,
                    DynamoDBMapperConfig.ConsistentReads consistentReads,
                    DynamoDBMapperConfig.TableNameOverride tableNameOverride)

非推奨です。

Constructs a new configuration object with the save behavior, consistent read behavior, and table name override given.

パラメータ:

saveBehavior - The DynamoDBMapperConfig.SaveBehavior to use, or null for default.

consistentReads - The DynamoDBMapperConfig.ConsistentReads to use, or null for default.

tableNameOverride - An override for the table name, or null for no override.

DynamoDBMapperConfig

public DynamoDBMapperConfig(DynamoDBMapperConfig.SaveBehavior saveBehavior)

非推奨です。

Constructs a new configuration object with the save behavior given.

DynamoDBMapperConfig

public DynamoDBMapperConfig(DynamoDBMapperConfig.ConsistentReads consistentReads)

非推奨です。

Constructs a new configuration object with the consistent read behavior given.

DynamoDBMapperConfig

public DynamoDBMapperConfig(DynamoDBMapperConfig.TableNameOverride tableNameOverride)

非推奨です。

Constructs a new configuration object with the table name override given.

メソッドの詳細

getSaveBehavior

public DynamoDBMapperConfig.SaveBehavior getSaveBehavior()

非推奨です。

Returns the save behavior for this configuration.

getConsistentReads

public DynamoDBMapperConfig.ConsistentReads getConsistentReads()

非推奨です。

Returns the consistent read behavior for this configuration.

getTableNameOverride

public DynamoDBMapperConfig.TableNameOverride getTableNameOverride()

非推奨です。

Returns the table name override for this configuration. This value will override the table name specified in a DynamoDBTable annotation, either by replacing the table name entirely or else by pre-pending a string to each table name. This is useful for partitioning data in multiple tables at runtime.
