Method Summary

void	addSelectionInterval(Interval interval) Makes logical OR of interval and this.intervals.
void	clear() Clears the selection
List<Interval>	getSelectionIntervals() Returns selection that relates to this text piece.
boolean	isFullySelected() Test if whole text is selected.
boolean	isPartlySelected() Test if something is selected, but not everything
void	setSelectionIntervals(Collection<Interval> intervals) Sets what is selected
void	subtractSelectionInterval(Interval interval) Subtracts interval from selection
void	xorSelectionIntervals(Collection<Interval> intervals) Makes XOR with this new interval

Method Detail

getSelectionIntervals

List<Interval> getSelectionIntervals()

Returns selection that relates to this text piece.

Returns:

list by copy, not overlapping Intervals within text piece.

isPartlySelected

boolean isPartlySelected()

Test if something is selected, but not everything

Returns:

true, if something is selected, but it is not fully selected

isFullySelected

boolean isFullySelected()

Test if whole text is selected.

Returns:

true, if whole ITextPieceKeeper is selected

setSelectionIntervals

void setSelectionIntervals(Collection<Interval> intervals)

Sets what is selected

Parameters:

intervals - Collection of intervals, that are in range text and are not overlaping

clear

void clear()

Clears the selection

addSelectionInterval

void addSelectionInterval(Interval interval)

Makes logical OR of interval and this.intervals. Holding property that intervlas are not overlaping.

Parameters:

interval - Interval to add to selection

subtractSelectionInterval

void subtractSelectionInterval(Interval interval)

Subtracts interval from selection

Parameters:

interval - Interval to subtract

xorSelectionIntervals

void xorSelectionIntervals(Collection<Interval> intervals)

Makes XOR with this new interval

Parameters:

intervals - Interval to XOR with others
