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.
