                                              Function fun,
                                              int i)

getOverloadCount

public static int getOverloadCount(FunctionName name)

get

public static Function get(java.lang.String keyspace,
                           FunctionName name,
                           java.util.List<? extends AssignmentTestable> providedArgs,
                           java.lang.String receiverKs,

Parameters:

keyspace - the current keyspace

name - the name of the function

providedArgs - the arguments provided for the function call

receiverKs - the receiver's keyspace

receiverCf - the receiver's table

receiverType - if the receiver type is known (during inserts, for example), this should be the type of the receiver

Throws:

InvalidRequestException
