TableKeysAndAttributes

public TableKeysAndAttributes(String tableName)

Method Detail

getPrimaryKeys

public List<PrimaryKey> getPrimaryKeys()

Return the list of primary keys (of the current table) to be included in a batch get-item operation.

withPrimaryKeys

public TableKeysAndAttributes withPrimaryKeys(PrimaryKey... primaryKeys)

Used to specify multiple primary keys. A primary key could consist of either a hash-key or both a hash-key and a range-key depending on the schema of the table.

withHashOnlyKeys

public TableKeysAndAttributes withHashOnlyKeys(String hashKeyName,
                                               Object... hashKeyValues)

Used to specify multiple hash-only primary keys.

Parameters:

hashKeyName - hash-only key name

hashKeyValues - a list of hash key values

withHashAndRangeKeys

public TableKeysAndAttributes withHashAndRangeKeys(String hashKeyName,
                                                   String rangeKeyName,
                                                   Object... alternatingHashAndRangeKeyValues)

Used to specify multiple hash-and-range primary keys.

Parameters:

hashKeyName - hash key name

rangeKeyName - range key name

alternatingHashAndRangeKeyValues - a list of alternating hash key value and range key value

addPrimaryKey

public TableKeysAndAttributes addPrimaryKey(PrimaryKey primaryKey)

Adds a primary key to be included in the batch get-item operation. A primary key could consist of either a hash-key or both a hash-key and a range-key depending on the schema of the table.

addHashOnlyPrimaryKey

public TableKeysAndAttributes addHashOnlyPrimaryKey(String hashKeyName,
                                                    Object hashKeyValue)

Adds multiple hash-only primary keys to be included in the batch get-item operation.

Parameters:

hashKeyName - name of the hash key attribute name

hashKeyValues - multiple hash key values

Returns:

the current instance for method chaining purposes
