Constructor Detail

TimestampDoubleMap

public TimestampDoubleMap()

Default constructor.

The map is empty with zero capacity.

TimestampDoubleMap

public TimestampDoubleMap(int capacity)

Constructor with capacity.

Using this constructor can improve performances if the number of timestamps is known in advance as it minimizes array resizes.

Parameters:

capacity - timestamp capacity

TimestampDoubleMap

public TimestampDoubleMap(double[] keys,
                          double[] vals)

Constructor with an initial timestamp map.

The keys array must be sorted and contain no duplicates.

Parameters:

keys - initial keys content

vals - initial values content

Method Detail

getDouble

public double getDouble(double timestamp)

Get the value for the given timestamp index.

Parameters:

timestamp - timestamp index

Returns:

found value or the default value if not found

Throws:

IllegalArgumentException - if the element doesn't exist

getDouble

public double getDouble(double timestamp,
                        double defaultValue)

Get the value for the given timestamp index.

Return defaultValue if the value is not found.

Parameters:

timestamp - timestamp index

defaultValue - default value

Returns:

found value or the default value if not found

getTypeClass

public Class<Double> getTypeClass()

Description copied from interface: TimeMap

Returns the value type class.

Specified by:

getTypeClass in interface TimeMap<Double,Double>

Specified by:

getTypeClass in class TimestampMap<Double>

Returns:

type class

toDoubleArray

public double[] toDoubleArray()

Returns an array of all values in this map.

This method may return a reference to the underlying array so clients should make a copy if the array is written to.

Returns:

array of all values

isSupported

public boolean isSupported(Estimator estimator)

Description copied from interface: TimeMap

Returns whether estimator is supported.

Specified by:

isSupported in interface TimeMap<Double,Double>

Specified by:

isSupported in class TimestampMap<Double>

Parameters:

estimator - estimator

Returns:

true if this map supports estimator
