Detailed Description

Token for activating surfaces.

This class represents a token used in LActivationTokenManager::activateSurfaceRequest().

For more details, refer to the LActivationTokenManager class documentation.

Member Function Documentation

creator()

LClient* creator ( ) const

inlinenoexcept

The client that requested the token creation.

Note

This may, but does not necessarily, refer to the same client that requests surface activation.

Returns

A valid pointer during LActivationTokenManager::createTokenRequest(), but it may return nullptr if accessed later, for example, if the client has disconnected.

origin()

LSurface* origin ( ) const

inlinenoexcept

The surface of the client that created the token.

This refers to the surface where the triggeringEvent() was sent.

Note

This is different from the surface intended to be activated.

Warning

Clients are not obligated to provide this hint, so this method may return nullptr.

triggeringEvent()

const LEvent* triggeringEvent ( ) const

inlinenoexcept

Triggering event.

Clients typically request token creation in response to an input event. The default implementation of LActivationTokenManager::createTokenRequest() only accepts requests containing a valid triggeringEvent().

See also

origin()

Warning

This value is optional, if the client does not specify a triggering event, this method returns nullptr.

timesUsed()

UInt32 timesUsed ( ) const

inlinenoexcept

Number of times the token has been used to activate a surface.

Incremented by 1 before each LActivationTokenManager::activateSurfaceRequest().

created()

const std::chrono::time_point<std::chrono::steady_clock>& created ( ) const

inlinenoexcept

Time the token was created.

See also

LActivationTokenManager::destroyTokensOlderThanMs().

Returns

The time point when the token was created.

toActivateAppId()

const std::string& toActivateAppId ( ) const

inlinenoexcept

The app ID of the client to be activated.

This value is optional, if the token creator does not assign an app ID, this method returns an empty string.

token()

const std::string& token ( ) const

inlinenoexcept

The unique and random token string generated by Louvre.

Returns

The token string.

destroy()

const std::unordered_map< std::string, LActivationToken * >::iterator destroy ( ) const

noexcept

Invalidates and destroys the token.

Removes it from LActivationTokenManager::tokens().

Once destroyed, no client will be able to use it to activate surfaces.

Returns

An iterator to the next element in LActivationTokenManager::tokens().
