Method Detail

apply

public Keyspaces apply(Keyspaces schema)

Description copied from interface: SchemaTransformation

Apply a statement transformation to a schema snapshot. Implementing methods should be side-effect free.

Parameters:

schema - Keyspaces to base the transformation on

Returns:

Keyspaces transformed by the statement

authorize

public void authorize(ClientState client)

Description copied from interface: CQLStatement

Perform any access verification necessary for the statement.

Parameters:

client - the current client state

getAuditLogContext

public AuditLogContext getAuditLogContext()

Description copied from interface: CQLStatement

Provides the context needed for audit logging statements.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

validate

public final void validate(ClientState state)

Description copied from interface: CQLStatement

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

Specified by:

validate in interface CQLStatement

Parameters:

state - the current client state

execute

public ResultMessage execute(QueryState state,
                             QueryOptions options,
                             long queryStartNanoTime)

Description copied from interface: CQLStatement

Execute the statement and return the resulting result or null if there is no result.

Specified by:

execute in interface CQLStatement

Parameters:

state - the current query state

options - options for this query (consistency, variables, pageSize, ...)

queryStartNanoTime - the timestamp returned by System.nanoTime() when this statement was received

executeLocally

public ResultMessage executeLocally(QueryState state,
                                    QueryOptions options)

Description copied from interface: CQLStatement

Variant of execute used for internal query against the system tables, and thus only query the local node.

Specified by:

executeLocally in interface CQLStatement

Parameters:

state - the current query state

execute

public ResultMessage execute(QueryState state,
                             boolean locally)
