Method Detail

getPositions

int[][] getPositions()

Returns the positions associated with the current ID. The positions are divided by field.

Returns:

A two-dimensional array of int. The contents of the i^th element of the array are the positions for the field whose ID is i. The positions stored at element 0 are those positions that are not in any named field. For each of the sub-arrays, the zeroth element of the array gives the number of word positions in that field.
