classdef MyClass < nelson.mixin.CustomCompactDisplayProvider
| Parameter | Description |
|---|---|
| obj | an object of a class deriving from nelson.mixin.CustomCompactDisplayProvider. |
| config | display configuration used for compact output. |
| width | maximum display width. |
| Parameter | Description |
|---|---|
| rep | compact display representation. |
Derive from nelson.mixin.CustomCompactDisplayProvider to control how an object is shown compactly when it appears inside a container such as a cell or a structure.
A subclass implements compactRepresentationForSingleLine(obj, config, width), which returns a nelson.display.CompactDisplayRepresentation describing the object on one line. The representation is usually built with the inherited helper widthConstrainedDataRepresentation(obj, config, width, 'StringArray', text), which joins the supplied data with the delimiter defined by config (a nelson.display.DisplayConfiguration) and truncates it with the configured ellipsis when it exceeds width characters. When an instance is displayed inside a container such as a cell, a structure field or a table column, the resulting text is used instead of the default [1x1 ClassName].
A companion method compactRepresentationForColumn(obj, config, width) can be implemented for column layouts, and fullDataRepresentation(obj, config, ...) builds an unconstrained representation. When these methods are not overridden, the default representation is used.
