Method Detail

build

public StaticTableMetadata build()

Builds an immutable instance of StaticTableMetadata from the values supplied to the builder.

addCustomMetadataObject

public StaticTableMetadata.Builder addCustomMetadataObject(String key,
                                                           Object object)

Adds a single custom object to the metadata, keyed by a string. Attempting to add a metadata object with a key that matches one that has already been added will cause an exception to be thrown.

Parameters:

key - a string key that will be used to retrieve the custom metadata

object - an object that will be stored in the custom metadata map

Throws:

IllegalArgumentException - if the custom metadata map already contains an entry with the same key

addIndexPartitionKey

public StaticTableMetadata.Builder addIndexPartitionKey(String indexName,
                                                        String attributeName,
                                                        AttributeValueType attributeValueType)

Adds information about a partition key associated with a specific index.

Parameters:

indexName - the name of the index to associate the partition key with

attributeName - the name of the attribute that represents the partition key

attributeValueType - the AttributeValueType of the partition key

Throws:

IllegalArgumentException - if a partition key has already been defined for this index

addIndexSortKey

public StaticTableMetadata.Builder addIndexSortKey(String indexName,
                                                   String attributeName,
                                                   AttributeValueType attributeValueType)

Adds information about a sort key associated with a specific index.

Parameters:

indexName - the name of the index to associate the sort key with

attributeName - the name of the attribute that represents the sort key

attributeValueType - the AttributeValueType of the sort key

Throws:

IllegalArgumentException - if a sort key has already been defined for this index

markAttributeAsKey

public StaticTableMetadata.Builder markAttributeAsKey(String attributeName,
                                                      AttributeValueType attributeValueType)

Declares a 'key-like' attribute that is not an actual DynamoDB key. These pseudo-keys can then be recognized by extensions and treated appropriately, often being protected from manipulations as those would alter the meaning of the record. One example usage of this is a 'versioned record attribute': although the version is not part of the primary key of the record, it effectively serves as such.

Parameters:

attributeName - the name of the attribute to mark as a pseudo-key

attributeValueType - the AttributeValueType of the pseudo-key
