`hasSetting`

Tests whether a settings group contains a setting of a given name.

Category: Environment and Settings > System Commands

Syntax

tf = hasSetting(G, name)

Returns true if group G has a setting called name.

Description

Only direct children of G are checked, and a child group with the same name does not count as a setting. Use it before addSetting to avoid the duplicate-name error.

Input arguments

G: A SettingsGroup object.
name: Name of the setting to look for.

Output arguments

tf: Logical scalar.

Example

Setting present and absent

s = settings;
g = addGroup(s, 'demo');
addSetting(g, 'Level', 'PersonalValue', 1);
disp(hasSetting(g, 'Level'))
disp(hasSetting(g, 'Other'))
removeGroup(s, 'demo');

Output

   1
   0
