`hasInstallationValue`

Tests whether a setting has a installation value.

Category: Environment and Settings > System Commands

Syntax

tf = hasInstallationValue(S)

Returns true when the installation layer of setting S holds a value.

Description

A setting can hold a temporary, personal, installation and factory value at the same time, and ActiveValue shows the first one set in that order. hasInstallationValue looks at one layer only, so it tells whether that layer would take part in the lookup.

Input arguments

S: A matlab.settings.Setting object.

Output arguments

tf: Logical scalar: true if the installation value is set.

Example

Query the installation layer

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