Interface IntCollection

All Superinterfaces:

All Known Subinterfaces:

public interface IntCollection
extends PrimitiveCollection<Integer>, IntIterable

Defines a collection of primitive int values.

This interface extends Collection allowing seamless integration with other APIs. All Collection methods can be used, using the primitive wrapper class Integer. However, it will be much more efficient to use the methods defined here.

Method Detail

iterator

IntIterator iterator()

Gets an iterator over this collection capable of accessing the primitive values.

Specified by:

iterator in interface Collection<Integer>

Specified by:

iterator in interface IntIterable

Specified by:

iterator in interface Iterable<Integer>

Returns:

an iterator over this collection, not null

contains

boolean contains(int value)

Checks whether this collection contains a specified primitive value.

Parameters:

value - the value to search for

Returns:

true if the value is found

containsAll

boolean containsAll(int[] values)

Checks if this collection contains all of the values in the specified array. If the specified array is empty, true is returned.

Parameters:

values - the values to search for, null treated as empty array

Returns:

true if all of the values are found

containsAll

boolean containsAll(IntCollection values)

Checks if this collection contains all of the values in the specified collection. If the specified collection is empty, true is returned.

Parameters:

values - the values to search for, null treated as empty collection

Returns:

true if all of the values are found

containsAll

boolean containsAll(int startInclusive,
                    int endInclusive)

Checks if this collection contain all the values in the specified range.

The range is defined to be inclusive of the start and end. If the start is greater than the end then the result is true as the range is equivalent to an empty collection.

Parameters:

startInclusive - the inclusive range start value

endInclusive - the inclusive range end value

Returns:

true if the collection contains the entire range

containsAny

boolean containsAny(int[] values)

Checks if this collection contains any of the values in the specified array. If the specified array is empty, false is returned.

Parameters:

values - the values to search for, null treated as empty array

Returns:

true if at least one of the values is found

containsAny

boolean containsAny(IntCollection coll)

Checks if this collection contains any of the values in the specified collection. If the specified collection is empty, false is returned.

Parameters:

coll - the values to search for, null treated as empty collection

Returns:

true if at least one of the values is found

containsAny

boolean containsAny(int startInclusive,
                    int endInclusive)

Checks if this collection contain any of the values in the specified range.

The range is defined to be inclusive of the start and end. If the start is greater than the end then the result is false as the range is equivalent to an empty collection.

Parameters:

startInclusive - the inclusive range start value

endInclusive - the inclusive range end value

Returns:

true if the collection contains at least one of the range

toIntArray

int[] toIntArray()

Gets the elements of this collection as an array.

Returns:

a new array containing a copy of the elements of this collection

toIntArray

int[] toIntArray(int[] array,
                 int startIndex)

Copies the elements of this collection into an array at a specified position. Previous values in the array are overwritten.

If the array specified is null a new array is created. If the array specified is large enough, it will be modified. If the array is not large enough, a new array will be created containing the values from the specified array before the startIndex plus those from this collection.

Parameters:

array - the array to add the elements to, null creates new array

startIndex - the position in the array to start setting elements

Returns:

the array with the populated collection, not null

Throws:

IndexOutOfBoundsException - if the index is negative

add

boolean add(int value)

Adds a primitive value to this collection (optional operation).

This method is optional, throwing an UnsupportedOperationException if the collection cannot be added to.

Parameters:

value - the value to add to this collection

Returns:

true if this collection was modified by this method call

Throws:

IllegalArgumentException - if value is rejected by this collection

UnsupportedOperationException - if not supported by this collection

addAll

boolean addAll(int[] values)

Adds an array of primitive values to this collection (optional operation).

This method is optional, throwing an UnsupportedOperationException if the collection cannot be added to.

Parameters:

values - the values to add to this collection, null treated as empty array

Returns:

true if this collection was modified by this method call

Throws:
