Constructor and Description
CreateKeyspaceStatement(java.lang.String name, KeyspaceAttributes attrs, boolean ifNotExists) Creates a new CreateKeyspaceStatement instance for a given keyspace name and keyword arguments.

Method Summary

Modifier and Type	Method and Description
Event.SchemaChange	announceMigration(QueryState queryState, boolean isLocalOnly) Announces the migration to other nodes in the cluster.
void	checkAccess(ClientState state) Perform any access verification necessary for the statement.
protected void	grantPermissionsToCreator(QueryState state) Schema alteration may result in a new database object (keyspace, table, role, function) being created capable of having permissions GRANTed on it.

void	validate(ClientState state) The CqlParser only goes as far as extracting the keyword arguments from these statements, so this method is responsible for processing and validating.

Constructor Detail

CreateKeyspaceStatement

public CreateKeyspaceStatement(java.lang.String name,
                               KeyspaceAttributes attrs,
                               boolean ifNotExists)

Creates a new CreateKeyspaceStatement instance for a given keyspace name and keyword arguments.

Parameters:

name - the name of the keyspace to create

attrs - map of the raw keyword arguments that followed the WITH keyword.

Method Detail

keyspace

public java.lang.String keyspace()

Overrides:

keyspace in class CFStatement

checkAccess

public void checkAccess(ClientState state)
                 throws UnauthorizedException

Description copied from interface: CQLStatement

Perform any access verification necessary for the statement.

Parameters:

state - the current client state

Throws:

UnauthorizedException

validate

public void validate(ClientState state)
              throws RequestValidationException

The CqlParser only goes as far as extracting the keyword arguments from these statements, so this method is responsible for processing and validating.

Parameters:

state - the current client state

Throws:

InvalidRequestException - if arguments are missing or unacceptable

RequestValidationException

announceMigration

public Event.SchemaChange announceMigration(QueryState queryState,
                                            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:

the schema change event corresponding to the execution of this statement, or null if no schema change has occurred (when IF NOT EXISTS is used, for example)

Throws:

RequestValidationException

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
