Detailed Description

Pure virtual interface for controlling switchable lenses from applications.

The eventual effect is dependent on all SR applications that are currently running. If there is only one SR application, this interface will provide direct control.

Constructor & Destructor Documentation

~SwitchableLensHint()

virtual SR::SwitchableLensHint::~SwitchableLensHint ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

create()

static SwitchableLensHint * SR::SwitchableLensHint::create ( SRContext &  context )

static

Creates a functional SwitchableLensHints instance.

Parameters

context

is the environment in which created senses are kept track of

Returns

SwitchableLensHints* which provides access to an available switchable lens controller

disable()

virtual void SR::SwitchableLensHint::disable ( )

pure virtual

Expresses preference to disable the lens to minimize the effect on the light transmitted through it.

enable()

virtual void SR::SwitchableLensHint::enable ( )

pure virtual

Expresses preference to enable the lens such that it affects the light transmitted through it.

isEnabled()

virtual bool SR::SwitchableLensHint::isEnabled ( )

pure virtual

Checks whether the Lens is currently enabled.

Returns

a boolean representing whether the Lens is currently enabled

isEnabledByPreference()

virtual bool SR::SwitchableLensHint::isEnabledByPreference ( )

pure virtual

This function returns true if any of already connected applications enabled the lense, otherwise returns false.

Returns

a boolean representing whether any applications have explicitly indicated that they want the lens to be on.

Exceptions

std::system_error

if mutex lock fails
