array

public final Array<T> array

Constructor Details

ArraySeq

public ArraySeq(Array<T> array)

Method Details

get

public final T get(int index)

Description copied from interface: BaseSeq

Return the value at the given index.

Specified by:

get in interface BaseSeq<T>

Parameters:

index - index of the element to return.

Returns:

the value at the given index.

forEach

public void forEach(Consumer<? super T> consumer)

Specified by:

forEach in interface BaseSeq<T>

Specified by:

forEach in interface Iterable<T>

forAll

public boolean forAll(Predicate<? super T> predicate)

Description copied from interface: Seq

Tests whether a predicate holds for all elements of this sequence.

Specified by:

forAll in interface Seq<T>

Parameters:

predicate - the predicate to use to test the elements.

Returns:

true if the given predicate p holds for all elements of this sequence, false otherwise.

indexWhere

public int indexWhere(Predicate<? super T> predicate,
 int start,
 int end)

Description copied from interface: Seq

Returns the index of the first element on which the given predicate returns true, or -1 if the predicate returns false for every sequence element.

// Finding index of first null value. final int index = seq.indexOf(o -> o == null); // Assert of no null values. assert (sequence.indexOf(o -> o == null) == -1);

Specified by:

indexWhere in interface Seq<T>

Parameters:

predicate - the search predicate.

start - the search start index

end - the search end index

Returns:

the index of the first element on which the given predicate returns true, or -1 if the predicate returns false for every sequence element.

lastIndexWhere

public int lastIndexWhere(Predicate<? super T> predicate,
 int start,
 int end)

Description copied from interface: Seq

Returns the index of the last element on which the given predicate returns true, or -1 if the predicate returns false for every sequence element.

Specified by:

lastIndexWhere in interface Seq<T>

Parameters:

predicate - the search predicate.

start - the search start index

end - the search end index

Returns:

the index of the last element on which the given predicate returns true, or -1 if the predicate returns false for every sequence element.

length

public int length()

Description copied from interface: BaseSeq

Return the length of this sequence. Once the sequence is created, the length can't be changed.

Specified by:

length in interface BaseSeq<T>

Returns:

the length of this sequence.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Description copied from interface: Seq

Returns the hash code value for this sequence. The hash code is defined as followed:

int hashCode = 1; final Iterator<E> it = seq.iterator(); while (it.hasNext()) { final E obj = it.next(); hashCode = 31*hashCode + (obj == null ? 0 : obj.hashCode()); }

Specified by:

hashCode in interface Seq<T>

Overrides:

hashCode in class Object

Returns:

the hash code value for this list

See Also:

• List.hashCode()
• Seq.hashCode(BaseSeq)

equals

public boolean equals(Object obj)

Description copied from interface: Seq

Compares the specified object with this sequence for equality. Returns true if and only if the specified object is also a sequence, both sequence have the same size, and all corresponding pairs of elements in the two sequences are equal. (Two elements e1 and e2 are equal if (e1==null ? e2==null : e1.equals(e2)).) This definition ensures that the equals method works properly across different implementations of the Seq interface.

Specified by:

equals in interface Seq<T>

Overrides:

equals in class Object

Parameters:

obj - the object to be compared for equality with this sequence.

Returns:

true if the specified object is equal to this sequence, false otherwise.

• List.equals(Object)
• Seq.equals(BaseSeq, Object)
