Member Function Documentation

offset()

void ossia::time_process::offset

(

ossia::time_value

date

)

get a #StateElement from the process on its parent #time_interval offset

don't call offset when the parent #time_interval is running

Parameters

date	offset date
pos	offset position (in [0;1] relative to parent nominal duration)

state()

virtual void ossia::time_process::state ( const ossia::token_request &  )

pure virtual

get a #StateElement from the process depending on its parent #time_interval date

don't call state when the parent #time_interval is not running

start()

void ossia::time_process::start ( )

virtual

start

Will be called when the parent time interval is started.

stop()

void ossia::time_process::stop ( )

virtual

stop

Will be called when the parent time interval is stopped.

pause()

void ossia::time_process::pause ( )

virtual

stop

Will be called when the parent time interval is paused.

resume()

void ossia::time_process::resume ( )

virtual

resume

Will be called when the parent time interval is resumed.

mute()

void ossia::time_process::mute

(

bool

m

)

mute Mutes or unmute the process.

mute(true) mutes the process. A muted process executes itself but does not send its state.

enable()

void ossia::time_process::enable

(

bool

m

)

Enables or disable the process.

Unlike a muted process, a disabled process does not execute at all.

set_loop_duration()

void ossia::time_process::set_loop_duration

(

time_value

v

)

Set how long a single loop lasts.

Only relevant if loops have been enabled.
