Example 1 with IntSink

use of primal.primitive.IntPrim.IntSink in project suite by stupidsing.

the class SparseMatrix method transpose.

public SparseMatrix transpose() {
    var pq = new PriorityQueue<>(IntIntPair.class, height, Comparator.comparingInt(IntIntPair::snd));
    var matrix1 = forInt(width_).map(i -> new Spans()).toList();
    var js = new int[height];
    IntSink enqRow = r -> {
        var j = js[r];
        if (j < matrix.get(r).size)
            pq.add(IntIntPair.of(r, j));
    };
    for (var r = 0; r < height; r++) enqRow.f(r);
    while (!pq.isEmpty()) {
        var pair = pq.extractMin();
        var r = pair.t0;
        var j = js[r]++;
        var spans = matrix.get(r);
        matrix1.get(spans.columns[j]).add(r, spans.values[j]);
        enqRow.f(r);
    }
    return new SparseMatrix(width_, height, matrix1);
}

Example 2 with IntSink

use of primal.primitive.IntPrim.IntSink in project suite by stupidsing.

the class DevMain method text.

private Text text(IRopeList<Character> text) {
    var starts = new IntsBuilder();
    var ends = new IntsBuilder();
    var p0 = IntMutable.of(-1);
    var size = text.size;
    IntSink lf = px -> {
        starts.append(p0.value() + 1);
        ends.append(px);
        p0.update(px);
    };
    for (var p = 0; p < size; p++) {
        var ch = text.get.apply(p);
        if (ch == '\n' || wrapSize < p - p0.value())
            lf.f(p);
    }
    if (1 < size - p0.value())
        lf.f(size);
    return new Text(text, starts.toInts().toArray(), ends.toInts().toArray());
