Constructor Detail

CreateTableStatement

public CreateTableStatement(CFName name,
                            TableParams params,
                            boolean ifNotExists,
                            java.util.Set<ColumnIdentifier> staticColumns)

Method Detail

checkAccess

public void checkAccess(ClientState state)
                 throws UnauthorizedException,
                        InvalidRequestException

Description copied from interface: CQLStatement

Perform any access verification necessary for the statement.

Parameters:

state - the current client state

Throws:

UnauthorizedException

InvalidRequestException

validate

public void validate(ClientState state)

Description copied from interface: CQLStatement

Perform additional validation required by the statment. To be overriden by subclasses if needed.

Parameters:

state - the current client state

announceMigration

public boolean announceMigration(boolean isLocalOnly)
                          throws RequestValidationException

Description copied from class: SchemaAlteringStatement

Announces the migration to other nodes in the cluster.

Specified by:

announceMigration in class SchemaAlteringStatement

Returns:

true if the execution of this statement resulted in a schema change, false otherwise (when IF NOT EXISTS is used, for example)

Throws:

RequestValidationException

changeEvent

public Event.SchemaChange changeEvent()

Specified by:

changeEvent in class SchemaAlteringStatement

grantPermissionsToCreator

protected void grantPermissionsToCreator(QueryState state)

Description copied from class: SchemaAlteringStatement

Schema alteration may result in a new database object (keyspace, table, role, function) being created capable of having permissions GRANTed on it. The creator of the object (the primary role assigned to the AuthenticatedUser performing the operation) is automatically granted ALL applicable permissions on the object. This is a hook for subclasses to override in order to perform that grant when the statement is executed.

Overrides:

grantPermissionsToCreator in class SchemaAlteringStatement

metadataBuilder

public CFMetaData.Builder metadataBuilder()

getCFMetaData

public CFMetaData getCFMetaData()

Returns a CFMetaData instance based on the parameters parsed from this CREATE statement, or defaults where applicable.

Returns:

a CFMetaData instance corresponding to the values parsed from this statement

Throws:

InvalidRequestException - on failure to validate parsed parameters

params

public TableParams params()
