CommandMap

Usage

use CommandMap;

or

import CommandMap;

proc akMsgSign(cmd: string, msgArgs: borrowed MessageArgs, st: borrowed SymTab): MsgTuple throws

• This is a dummy function to get the signature of the Arkouda

• server FCF. Ideally, the func() function would be able to

• construct the FCF type, but there is no way to generate a

• FCF that throws using func() today.

proc akBinMsgSign(cmd: string, msgArgs: borrowed MessageArgs, st: borrowed SymTab): bytes throws

• Just like akMsgSign, but Messages which have a binary return

• require a different signature

proc arrayMsgSign(cmd: string, msgArgs: borrowed MessageArgs, ref data: bytes, st: borrowed SymTab): MsgTuple throws

var commandMap: map(string, f.type)

var commandMapBinary: map(string, b.type)

var commandMapArray: map(string, a.type)

var moduleMap: map(string, string)

var usedModules: set(string)

proc registerFunction(cmd: string, fcf: f.type)

• Register command->function in the CommandMap

• This binds a server command to its corresponding function matching the standard

• function signature & MsgTuple return type

proc registerFunction(cmd: string, fcf: f.type, modName: string)

proc writeUsedModules(fmt: string = "cfg")

proc registerBinaryFunction(cmd: string, fcf: b.type)

• Register command->function in the CommandMap for Binary returning functions

• This binds a server command to its corresponding function matching the standard

• function signature but returning “bytes”

proc registerBinaryFunction(cmd: string, fcf: b.type, modName: string)

proc registerArrayFunction(cmd: string, fcf: a.type)

proc dumpCommandMap(): string throws

• Dump the combined contents of the command maps as a single json encoded string

proc executeCommand(cmd: string, msgArgs, st) throws
