sequence

private final CharSequence sequence

See Also:

SequenceCharIterator(CharSequence)

length

private final int length

The length of the sequence.

index

private int index

The current index in sequence.

Constructor Detail

SequenceCharIterator

public SequenceCharIterator(CharSequence sequence)

The constructor.

Parameters:

sequence - the CharSequence to iterate char by char.

Method Detail

hasNext

public boolean hasNext()

This method determines whether there is a next char available or the end of this iterator has been reached.

Specified by:

hasNext in interface CharIterator

Returns:

true if there is at least one next char available, or false if the end of this iterator has been reached and further calls of CharIterator.next() will return CharIterator.END_OF_ITERATOR.

See Also:

CharIterator.next(), Iterator.hasNext()

next

public char next()

This method returns the next character to iterate or CharIterator.END_OF_ITERATOR if the end of this iterator has been reached. If CharIterator.END_OF_ITERATOR is returned further calls will always return CharIterator.END_OF_ITERATOR.

Specified by:

next in interface CharIterator

Returns:

the next character or CharIterator.END_OF_ITERATOR if the end of this iterator has been reached.
