Method Detail

iterator

public TDoubleIterator iterator()

Creates an iterator over the values of the collection. The iterator supports element deletion.

Specified by:

iterator in interface TDoubleCollection

Returns:

an TDoubleIterator value

getNoEntryValue

public double getNoEntryValue()

Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.

Specified by:

getNoEntryValue in interface TDoubleCollection

Returns:

the value that represents null

size

public int size()

Returns the number of elements in this collection (its cardinality). If this collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Specified by:

size in interface TDoubleCollection

Returns:

the number of elements in this collection (its cardinality)

isEmpty

public boolean isEmpty()

Returns true if this collection contains no elements.

Specified by:

isEmpty in interface TDoubleCollection

Returns:

true if this collection contains no elements

contains

public boolean contains(double entry)

Returns true if this collection contains the specified element.

Specified by:

contains in interface TDoubleCollection

Parameters:

entry - an double value

Returns:

true if the collection contains the specified element.

toArray

public double[] toArray()

Returns an array containing all of the elements in this collection. If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

The returned array will be "safe" in that no references to it are maintained by this collection. (In other words, this method must allocate a new array even if this collection is backed by an array). The caller is thus free to modify the returned array.

This method acts as bridge between array-based and collection-based APIs.

Specified by:

toArray in interface TDoubleCollection

Returns:

an array containing all the elements in this collection

toArray

public double[] toArray(double[] dest)

Returns an array containing elements in this collection.

If this collection fits in the specified array with room to spare (i.e., the array has more elements than this collection), the element in the array immediately following the end of the collection is collection to TDoubleCollection.getNoEntryValue(). (This is useful in determining the length of this collection only if the caller knows that this collection does not contain any elements representing null.)

If the native array is smaller than the collection size, the array will be filled with elements in Iterator order until it is full and exclude the remainder.

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

Specified by:

toArray in interface TDoubleCollection

Parameters:

dest - the array into which the elements of this collection are to be stored.

Returns:

an double[] containing all the elements in this collection

add

public boolean add(double entry)

Description copied from interface: TDoubleCollection

Inserts a value into the collection.

Specified by:

add in interface TDoubleCollection

Parameters:

entry - a double value

Returns:

true if the collection was modified by the add operation

remove

public boolean remove(double entry)

Removes entry from the collection.

Specified by:

remove in interface TDoubleCollection

Parameters:

entry - an double value

Returns:

true if the collection was modified by the remove operation.

containsAll

public boolean containsAll(java.util.Collection<?> collection)

Tests the collection to determine if all of the elements in collection are present.

Specified by:

containsAll in interface TDoubleCollection

Parameters:

collection - a Collection value

Returns:

true if all elements were present in the collection.

containsAll

public boolean containsAll(TDoubleCollection collection)

Tests the collection to determine if all of the elements in TDoubleCollection are present.

Specified by:

containsAll

public boolean containsAll(double[] array)

Tests the collection to determine if all of the elements in array are present.

Specified by:

addAll

public boolean addAll(java.util.Collection<? extends java.lang.Double> collection)

Adds all of the elements in collection to the collection.
