Constructor Detail

Sequence

public Sequence(List<U> originalSequence)

Creates a new instance. The start and end indexes will be taken as zero and the original sequence size.

Parameters:

originalSequence - the original sequence, cannot be null

Sequence

public Sequence(List<U> originalSequence,
                int startIndex,
                int endIndex)

Creates a new instance.

Parameters:

originalSequence - the original sequence, cannot be null

startIndex - the start index (inclusive)

endIndex - the end index (exclusive)

Method Detail

get

public U get(int index)

Returns the element at the specified position in this sequence.

Parameters:

index - the index of the element to return

Returns:

the element at the specified position in this sequence

Throws:

IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size())

size

public int size()

Returns the number of elements in this sequence.

Returns:

the number of elements in this sequence

isEmpty

public boolean isEmpty()

Returns true if this sequence contains no elements.

Returns:

true if this sequence contains no elements, false otherwise

contains

public boolean contains(U element,
                        BiFunction<U,U,Boolean> equalityFunction)

Returns true if this sequence contains the specified element.

Parameters:

element - the element whose presence in this sequence is to be tested

equalityFunction - the function of equality of elements, cannot be null

Returns:

true if this sequence contains the specified element, false otherwise

subSequence

public ComparisonUtils.Sequence<U> subSequence(int fromIndex,
                                               int toIndex)

Returns a view of the portion of this sequence between the specified fromIndex (inclusive) and toIndex (exclusive).

Parameters:

fromIndex - the low endpoint (inclusive) of the subSequence

toIndex - the high endpoint (exclusive) of the subSequence

Returns:

a view of the specified range within this sequence, never null

toList

public List<U> toList()

Returns this sequnce as list.

Returns:

this sequnce as list, never null

reverse

public ComparisonUtils.Sequence<U> reverse()

Reverses the order of the elements in this sequnce.

Returns:

the sequence obtained from this sequnce by reversing the order of the elements, never null
