Purpose

This module reverses any ListBase object.

Usage

Connect a Base object that is derived from ListBase, and press Update.

Windows

Default Panel

Input Fields

inList

name: inList, type: MLBase

A ListBase-derived Base object.

Output Fields

outList

name: outList, type: MLBase

An object of the same type as the input object, with reversed element order.

Parameter Fields

Field Index

[]: Trigger

Clear: Trigger

doNotClearOnFailedUpdate: Bool

Has Valid Output: Bool

On Input Change Behavior: Enum

Status Code: Enum

Status Message: String

Update: Trigger

Visible Fields

Update

name: update, type: Trigger

Initiates update of all output field values.

Clear

name: clear, type: Trigger

Clears all output field values to a clean initial state.

On Input Change Behavior

name: onInputChangeBehavior, type: Enum, default: Clear, deprecated name: shouldAutoUpdate,shouldUpdateAutomatically

Declares how the module should react if a value of an input field changes.

Values:

Title	Name	Deprecated Name	Description
Update	Update	TRUE	Update outputs.
Clear	Clear	FALSE	Clear outputs.

Status Code

name: statusCode, type: Enum, persistent: no

Reflects module’s status (successful or failed computations) as one of some predefined enumeration values.

Values:

Title	Name	Description
Ok	Ok	Inputs could be processed.
Invalid input object	Invalid input object	The input object is invalid, e.g., NULL or not ListBase-derived.
Invalid input parameter	Invalid input parameter	The input parameters are invalid, e.g., the indicated range is not within the input object range.
Internal error	Internal error	An internal error occurred.

Status Message

name: statusMessage, type: String, persistent: no

Gives additional, detailed information about status code as human-readable message.

Has Valid Output

name: hasValidOutput, type: Bool, persistent: no

Indicates validity of output field values (success of computation).

[]

name: updateDone, type: Trigger, persistent: no

Notifies that an update was performed (Check status interface fields to identify success or failure).

Hidden Fields

doNotClearOnFailedUpdate

name: doNotClearOnFailedUpdate, type: Bool, persistent: no

Prevents automated clear after update failed. This does not affect status fields. It enables the developer to analyze module’s state after failure.
