Constructor Details

WrappedDoubleArray

protected WrappedDoubleArray(double[] array)

Internal constructor for Conversions.WrappedDoubleArray.

Parameters:

array - the to-be-wrapped array. May be null which will cause any method on the created object to fail with a NullPointerException.

Method Details

create

@Pure
public static Conversions.WrappedDoubleArray create(double[] array)

Creates a new Conversions.WrappedDoubleArray that is backed by the given primitive array.

Parameters:

array - the to-be-wrapped array. May be null which will cause any method on the resulting object to fail.

Returns:

the wrapped array. Never null.

get

public Double get(int index)

Specified by:

get in interface List<Double>

Specified by:

get in class AbstractList<Double>

Throws:

NullPointerException - if the wrapped array was null.

IndexOutOfBoundsException

set

public Double set(int index,
 Double element)

Specified by:

set in interface List<Double>

Overrides:

set in class AbstractList<Double>

Throws:

NullPointerException - if the wrapped array was null.

ClassCastException

NullPointerException

IllegalArgumentException

IndexOutOfBoundsException

indexOf

public int indexOf(Object o)

Specified by:

indexOf in interface List<Double>

Overrides:

indexOf in class AbstractList<Double>

Throws:

NullPointerException - if the wrapped array was null.

lastIndexOf

public int lastIndexOf(Object o)

Specified by:

lastIndexOf in interface List<Double>

Overrides:

lastIndexOf in class AbstractList<Double>

Throws:

NullPointerException - if the wrapped array was null.

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<Double>

Specified by:

contains in interface List<Double>

Overrides:

contains in class AbstractCollection<Double>

Throws:

size

public int size()

Specified by:

size in interface Collection<Double>

Specified by:

size in interface List<Double>

Specified by:

size in class AbstractCollection<Double>

Throws:

NullPointerException - if the wrapped array was null.

internalToArray

public double[] internalToArray()

Returns the underlying array in an unsafe manner. That is, modification of the array will be reflected by this list and vice versa.

Returns:

the underlying array. May be null if the list was created with a null argument.
