Examples with TermContainerToOpMap nars.index.util.TermContainerToOpMap used on opensource projects

Example 1 with TermContainerToOpMap

use of nars.index.util.TermContainerToOpMap in project narchy by automenta.

the class CaffeineIndex2 method get.

@Override
public Termed get(Term x, boolean createIfMissing) {
    if (x.volume() > nar.termVolumeMax.intValue())
        // quick check to avoid creating a vector for a term that will be invalid anyway
        return null;
    assert (!(x instanceof Variable)) : "variables should not be stored in index";
    Op op = x.op();
    TermContainerToOpMap<Termed> v;
    if (createIfMissing) {
        v = vectors.get(vector(x), k -> {
            TermContainerToOpMap<Termed> t = new TermContainerToOpMap<>(k);
            Termed p = nar.conceptBuilder.apply(x, null);
            if (p != null)
                t.compareAndSet(op.id, null, p);
            return t;
        });
    } else {
        v = vectors.getIfPresent(vector(x));
    }
    return v != null ? v.get(op.id) : null;
