Method Detail

removeAll

public int removeAll(DoubleLookupContainer c)

Default implementation uses a predicate for removal.

Specified by:

removeAll in interface DoubleCollection

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(DoubleLookupContainer c)

Keeps all elements in this collection that are present in c. Runs in time proportional to the number of elements in this collection. Equivalent of sets intersection.

Specified by:

retainAll in interface DoubleCollection

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(DoublePredicate predicate)

Keeps all elements in this collection for which the given predicate returns true.

Specified by:

retainAll in interface DoubleCollection

Returns:

Returns the number of removed elements.

toArray

public double[] toArray(double[] target)

Default implementation for: Copies all elements of this container to an existing array of the same type.

Specified by:

toArray in interface DoubleContainer

Parameters:

target - The target array must be large enough to hold all elements, i.e >= DoubleContainer.size().

Returns:

Returns the target argument for chaining.

toArray

public double[] toArray()

Copies all elements from this container to an array.

The returned array is sized to match exactly the number of elements of the container.

If you need an array of the type identical with this container's generic type, use #toArray(Class).

Specified by:

toArray in interface DoubleContainer

See Also:

#toArray(Class)

toString

public java.lang.String toString()

Convert the contents of this container to a human-friendly string.

Overrides:

toString in class java.lang.Object

isEmpty

public boolean isEmpty()

Description copied from interface: DoubleContainer

True if there is no elements in the container, equivalent to size() == 0

Specified by:

isEmpty in interface DoubleContainer
