Detailed Description

The SoOneShot class is a timer that runs for a configurable time and then stops.

Member Enumeration Documentation

◆ Flags

enum SoOneShot::Flags

There are two flags available: RETRIGGERABLE will cause the engine to restart at 0 if the SoOneShot::trigger field is activated during a run (otherwise the trigger is ignored during runs).

HOLD_FINAL will make the engine outputs keep their values after a run, instead of resetting them.

Constructor & Destructor Documentation

◆ SoOneShot()

SoOneShot::SoOneShot ( void )

Default constructor.

◆ ~SoOneShot()

SoOneShot::~SoOneShot ( void )

protectedvirtual

Destructor is protected to avoid explicit destruction.

Member Function Documentation

◆ getTypeId()

SoType SoOneShot::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

◆ getFieldData()

const SoFieldData * SoOneShot::getFieldData ( void ) const

virtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

◆ getOutputData()

const SoEngineOutputData * SoOneShot::getOutputData ( void ) const

virtual

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

Member Data Documentation

◆ timeIn

SoSFTime SoOneShot::timeIn

Input time source. Connected by default to the realTime global field, but the application programmer is free to change this to any other time source.

◆ duration

SoSFTime SoOneShot::duration

The time the engine should run for when it is triggered. Defaults to 1 second.

◆ trigger

SoSFTrigger SoOneShot::trigger

A pulse on this input field starts the engine.

◆ flags

SoSFBitMask SoOneShot::flags

Control flags. See SoOneShot::Flags.

◆ disable

SoSFBool SoOneShot::disable

Set to TRUE to disable the engine completely.

◆ timeOut

SoEngineOutput SoOneShot::timeOut

(SoSFTime) Output time. Will run from 0 to the value of SoOneShot::duration.

◆ isActive

SoEngineOutput SoOneShot::isActive

(SoSFBool) TRUE while the engine is running, FALSE otherwise.

◆ ramp

SoEngineOutput SoOneShot::ramp

(SoSFFloat) Will run from 0 to 1 during the active period.
