Method Detail

getBindVariables

default java.util.List<ColumnSpecification> getBindVariables()

Returns all bind variables for the statement

getPartitionKeyBindVariableIndexes

default short[] getPartitionKeyBindVariableIndexes()

Returns an array with the same length as the number of partition key columns for the table corresponding to table. Each short in the array represents the bind index of the marker that holds the value for that partition key column. If there are no bind markers for any of the partition key columns, null is returned.

getFunctions

default java.lang.Iterable<Function> getFunctions()

Return an Iterable over all of the functions (both native and user-defined) used by any component of the statement

Returns:

functions all functions found (may contain duplicates)

authorize

void authorize(ClientState state)

Perform any access verification necessary for the statement.

Parameters:

state - the current client state

validate

void validate(ClientState state)

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

Parameters:

state - the current client state

execute

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

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

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

ResultMessage executeLocally(QueryState state,
                             QueryOptions options)

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

Parameters:

state - the current query state

getAuditLogContext

AuditLogContext getAuditLogContext()

Provides the context needed for audit logging statements.

hasConditions

default boolean hasConditions()

Whether or not this CQL Statement has LWT conditions
