Public constructors
PrescribedSegmentFinder
public PrescribedSegmentFinder (int[] segments)
Create a SegmentFinder with segments stored in an array, where i-th segment's start is
stored at segments[2 * i] and end is stored at segments[2 * i + 1] respectively.
It is required that segments do not overlap, and are already sorted by their start
indices.
Parameters |
segments |
int : the array that stores the segment ranges. |
Throws |
IllegalArgumentException |
if the given segments array's length is not even; the
given segments are not sorted or there are segments overlap with others. |

nextStartBoundary
public int nextStartBoundary (int offset)
Returns the character offset of the next text segment start boundary after the specified
character offset, or DONE

Parameters |
offset |
int : Value is 0 or greater |
previousEndBoundary
public int previousEndBoundary (int offset)
Returns the character offset of the previous text segment end boundary before the specified
character offset, or DONE
if there are none.
Parameters |

int : Value is 0 or greater |
previousStartBoundary
public int previousStartBoundary (int offset)
Returns the character offset of the previous text segment start boundary before the specified
character offset, or DONE
