Detailed Description

ValueAccumulatorBase is the base class for the Value Accumulator implementations for different data types.

It defines the common property and message types for different Value Accumulators.

See also: IntValueAccumulator, FloatValueAccumulator

Since: Kanzi 3.9.2

Member Enumeration Documentation

enum kanzi::ValueAccumulatorBase::BoundType

strong

Sets how a Value Accumulator handles the increments when it reaches the limits of the range of increments.

For an IntValueAccumulator you can set the boundaries with the IntValueAccumulator::MinimumAccumulatedValueProperty and IntValueAccumulator::MaximumAccumulatedValueProperty.
For an FloatValueAccumulator you can set the boundaries with the FloatValueAccumulator::MinimumAccumulatedValueProperty and FloatValueAccumulator::MaximumAccumulatedValueProperty.

Enumerator
Loop	Limits the total accumulated value between the maximum and minimum values by wrapping the value.
Clamp	Limits the total accumulated value between the maximum and minimum values by clamping the value.

Constructor & Destructor Documentation

Constructor.

Parameters

domain	Domain.
name	Name of the ValueAccumulator.

Member Function Documentation

bool kanzi::ValueAccumulatorBase::isAutoplay ( ) const

Gets the value of AutoplayProperty.

See also: setAutoplay()

void kanzi::ValueAccumulatorBase::setAutoplay ( bool enabled )

Sets the value of AutoplayProperty.

See also: isAutoplay()

BoundType kanzi::ValueAccumulatorBase::getBoundType ( ) const

Gets the value of the BoundTypeProperty.

See also: setBoundType()

void kanzi::ValueAccumulatorBase::setBoundType ( BoundType boundType )

Sets the value of the BoundTypeProperty.

See also: getBoundType()

int kanzi::ValueAccumulatorBase::getIncrementTimeInterval ( ) const

Gets the value of the IncrementTimeIntervalProperty.

Returns: The frequency in milliseconds at which the Value Accumulator adds the input property to the target property.

See also: setIncrementInterval()

void kanzi::ValueAccumulatorBase::setIncrementTimeInterval ( int frequencyInMilliseconds )

Sets the value of the IncrementTimeIntervalProperty.

Parameters

frequencyInMilliseconds The frequency in milliseconds at which the Value Accumulator adds the input property to the target property.

See also: getIncrementInterval()

static PropertyTypeEditorInfoSharedPtr kanzi::ValueAccumulatorBase::makeEditorInfo ( )

static

void kanzi::ValueAccumulatorBase::start ( )

Starts a Value Accumulator.

When a Value Accumulator starts, it resets the accumulated value to zero and starts incrementing the value. ValueAccumulatorBase calls this function when it receives a StartMessage.

void kanzi::ValueAccumulatorBase::stop ( )

Stops the Value Accumulator.

When a Value Accumulator stops, it resets the accumulated value to zero and stops incrementing the value. ValueAccumulatorBase calls this function when it receives a StopMessage.

void kanzi::ValueAccumulatorBase::pause ( )

Pauses the Value Accumulator.

The paused Value Accumulator continues applying the value that has been accumulated so far, but stops incrementing it. ValueAccumulatorBase calls this function when it receives a PauseMessage.

void kanzi::ValueAccumulatorBase::resume ( )

Resumes a paused Value Accumulator.

The resumed Value Accumulator continues applying and incrementing the accumulated value. ValueAccumulatorBase calls this function when it receives a ResumeMessage.
