Description copied from class: ModificationStatement

Convert statement into a list of mutations to apply on the server

Specified by:

getMutations in class ModificationStatement

Parameters:

variables - value for prepared statement markers

local - if true, any requests (for collections) performed by getMutation should be done locally only.

cl - the consistency to use for the potential reads involved in generating the mutations (for lists set/delete operations)

now - the current timestamp in microseconds to use if no timestamp is user provided.

Returns:

list of the mutations

Throws:

InvalidRequestException - on invalid requests

RequestExecutionException

RequestValidationException
