Method Detail

ifNotExists

@NonNull
CreateDseAggregateStart ifNotExists()

Adds IF NOT EXISTS to the create aggregate specification. This indicates that the aggregate should not be created if it already exists.

orReplace

@NonNull
CreateDseAggregateStart orReplace()

Adds OR REPLACE to the create aggregate specification. This indicates that the aggregate should replace an existing aggregate with the same name if it exists.

withParameter

@NonNull
CreateDseAggregateStart withParameter(@NonNull
                                               DataType paramType)

Adds a parameter definition in the CREATE AGGREGATE statement.

Parameter keys are added in the order of their declaration.

To create the data type, use the constants and static methods in DataTypes, or SchemaBuilder.udt(CqlIdentifier, boolean).

withSFunc

@NonNull
CreateDseAggregateStateFunc withSFunc(@NonNull
                                               CqlIdentifier sfuncName)

Adds SFUNC to the create aggregate specification. This is the state function for each row.

withSFunc

@NonNull
default CreateDseAggregateStateFunc withSFunc(@NonNull
                                                       String sfuncName)

Shortcut for withSFunc(CqlIdentifier.fromCql(sfuncName)).
