ServerErrors

Usage

use ServerErrors;

or

import ServerErrors;
class OutOfBoundsError : Error
class ErrorWithContext : Error

  • Generates an error message that provides a fuller context to the error

  • by including the line number, proc name, and module name from which the

  • Error was thrown.

var lineNumber : int
var routineName : string
var moduleName : string
var errorClass : string
var publishMsg : string
proc init(msg: string, lineNumber: int, routineName: string, moduleName: string, errorClass: string = "ErrorWithContext")

  • Accepts parameters that are used to generate the detailed, context-rich

  • error message accessible via ErrorWithContext.message() as well as the

  • client-formatted error message accessible via ErrorWithContext.publish()

proc init()
proc publish() : string

  • Returns only the msg init parameter element prepended with “Error: “,

  • which can be used to report errors back to the Arkouda client in a format

  • understandable to front-end developers as well as users.

class DatasetNotFoundError : ErrorWithContext

  • The DatasetNotFoundError is thrown if there is no dataset in the file

  • being accessed.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class WriteModeError : ErrorWithContext

  • The WriteModeError is thrown if a file save operation is executed in append mode

  • on a brand new file lacking any current datasets.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class NotHDF5FileError : ErrorWithContext

  • The NotHDF5FileError is thrown if it is determined a file is not HDFF file.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class HDF5FileFormatError : ErrorWithContext

  • The HDF5FileFormatError is thrown if there is an error in parsing the HDF5 file.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class MismatchedAppendError : ErrorWithContext

  • The MismatchedAppendError is thrown if an attempt is made to append a dataset to

  • an HDF5 file where the number of locales for the current Arkouda instance differs

  • from the number of locales in the Arkouda instance that wrote the original files.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class SegStringError : ErrorWithContext

  • The SegStringError is thrown if the file corresponding to the SegString lacks either the

  • SEGSTRING_OFFSET_NAME or SEGSTRING_VALUE_NAME dataset.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class ArgumentError : ErrorWithContext

  • The ArgumentError is thrown if there is a problem with 1.n arguments passed

  • into a function.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class NotImplementedError : ErrorWithContext

  • The NotImplementedError is thrown if the requested operation has not been implemented

  • for the specified data type(s) and/or command type.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class UnknownSymbolError : ErrorWithContext

  • The UnknownSymbolError is thrown if there is not entry in the SymTab.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class UnsupportedOSError : ErrorWithContext

  • The UnsupportedOSError is thrown if a function cannot be executed on the host OS.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class IOError : ErrorWithContext

  • The IOError is thrown if there is an error in IO code.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class OverMemoryLimitError : ErrorWithContext

  • The OverMemoryLimitError is thrown if the projected memory required for a method

  • invocation will exceed available, free memory on 1..n locales

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
class ConfigurationError : ErrorWithContext

  • The ConfigurationError if the current instance of the server was not

  • configured to complete a requested operation.

proc init(msg: string, lineNumber: int, routineName: string, moduleName: string)
proc init()
proc generateErrorContext(msg: string, lineNumber: int, moduleName: string, routineName: string, errorClass: string = "ErrorWithContext") : string

  • Generates a detailed, context-rich error message for errors such as instances of

  • built-in Chapel Errors in a format that matches the Arkouda ErrorWithContext

  • error message format.

proc getErrorWithContext(lineNumber: int, moduleName: string, routineName: string, msg: string, errorClass: string) throws

  • Factory method for generating ErrorWithContext objects that include an error

  • message as well as the line number, routine name, and module name where the

  • error was thrown.
