Modifier and Type	Method	Description
void	add(double toAdd)
protected Double	getInterpolatedValue(Time t, DoubleResource r)	Performs the logic for interpolation for the input time and resource.
Double	interpval(Time t)	Returns the value of the resource at a time, linearly interpolating if the query time is not one in which the resource was explicitly set.
protected Double	linearlyInterpolate(Time interpolateTime, Time t1, Time t2, Double v1, Double v2)	Performs linear interpolation using y = mx + b
Double	profile(Time t)	Returns the default value of the resource before it is set() to a new value.

Method Details

profile

public Double profile(Time t)

Description copied from class: Resource

Returns the default value of the resource before it is set() to a new value. Must be abstract since different data types have different intuitive defaults.

Specified by:

profile in class Resource<Double>

Parameters:

t - The time one wants the default value at. Used for custom resources that may have time-varying profiles.

Returns:

add

public void add(double toAdd)

subtract

public void subtract(double toSubtract)

interpval

public Double interpval(Time t)

Returns the value of the resource at a time, linearly interpolating if the query time is not one in which the resource was explicitly set. This is in contrast to valueAt, which, if faced with querying the value at a time the resource was not set, returns the most recent update to the resource

Parameters:

t - The time at which you want the interpolated value of the resource

Returns:

The value of the resource as interpolated between two explicitly calculated values

getInterpolatedValue

protected Double getInterpolatedValue(Time t,
 DoubleResource r)

Performs the logic for interpolation for the input time and resource. This method is abstracted from interpval because IntegratingResource also has the same logic.

linearlyInterpolate

protected Double linearlyInterpolate(Time interpolateTime,
 Time t1,
 Time t2,
 Double v1,
 Double v2)

Performs linear interpolation using y = mx + b

update

public void update()

Description copied from class: Resource

No-op method that adapters can override in custom resources

Specified by:

update in interface ResourceContainer

Overrides:

update in class Resource<Double>
