Enum Constant Detail

STEPWISE

public static final Interpolation STEPWISE

Stepwise interpolation of demand.

LINEAR

public static final Interpolation LINEAR

Linear interpolation of demand.

Method Detail

values

public static Interpolation[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Interpolation c : Interpolation.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Interpolation valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

interpolate

abstract org.djunits.value.vdouble.scalar.Frequency interpolate(org.djunits.value.vdouble.scalar.Frequency frequency0,
                                                                org.djunits.value.vdouble.scalar.Duration time0,
                                                                org.djunits.value.vdouble.scalar.Frequency frequency1,
                                                                org.djunits.value.vdouble.scalar.Duration time1,
                                                                org.djunits.value.vdouble.scalar.Duration time)

Interpolate between given frequencies.

Parameters:

frequency0 - frequency at time0

time0 - time of frequency0 (≤ time)

frequency1 - frequency at time1

time1 - time of frequency1 (> time)

time - time0 ≤ time < time1

Returns:

interpolated frequency

integrate

abstract int integrate(org.djunits.value.vdouble.scalar.Frequency frequency0,
                       org.djunits.value.vdouble.scalar.Duration time0,
                       org.djunits.value.vdouble.scalar.Frequency frequency1,
                       org.djunits.value.vdouble.scalar.Duration time1)

Integrates to the number of trips in given period.

Parameters:

frequency0 - frequency at time0

time0 - time of frequency0 (≤ time)

frequency1 - frequency at time1

time1 - time of frequency1 (> time)

Returns:

number of trips in given period
