ArrayBacked

public ArrayBacked(int[] ranges)

Method Details

copy

public RangeIterator.ArrayBacked copy()

hasNext

public boolean hasNext()

Description copied from interface: RangeIterator

Checks if the iterator has more ranges. If hasNext() returns false, calling next thereafter results in undefined behavior.

Specified by:

hasNext in interface RangeIterator

Returns:

whether there is another range.

start

public int start()

Description copied from interface: RangeIterator

Start of the current range.

Calling start() without calling next() at least once results in undefined behavior.

Specified by:

start in interface RangeIterator

Returns:

the start of the current range.

end

public int end()

Description copied from interface: RangeIterator

End of the current range (exclusive).

Calling end() without calling next() at least once results in undefined behavior.

Specified by:

end in interface RangeIterator

Returns:

the end of the current range (exclusive).

next

public void next()

Description copied from interface: RangeIterator

Advance the iterator to the next range. Only call after hasNext() has returned true.

Specified by:

next in interface RangeIterator

next

public int next(short[] buffer,
 int offset,
 int maxShortCount)

Description copied from interface: RangeIterator

Get the next batch of ranges.

Specified by:

next in interface RangeIterator

Parameters:

buffer - a short array where consecutive pairs of (start, end-1) values will be stored.

offset - where in buffer to start storing range boundary values.

maxShortCount - maximum number of ranges that can be written to buffer; buffer should have at least space for 2*maxRanges shorts starting at offset.

Returns:

how many ranges were written in buffer; this is two times the individual elements written.
