Examples with Matrix gov.sandia.n2a.language.type.Matrix used on opensource projects

Example 36 with Matrix

use of gov.sandia.n2a.language.type.Matrix in project n2a by frothga.

the class ReadMatrix method open.

public Matrix open(Instance context) {
    Simulator simulator = Simulator.instance.get();
    // absence of simulator indicates analysis phase, so opening files is unnecessary
    if (simulator == null)
        return null;
    String path = ((Text) operands[0].eval(context)).value;
    Object A = simulator.holders.get(path);
    if (A == null) {
        A = Matrix.factory(simulator.jobDir.resolve(path));
        simulator.holders.put(path, A);
    } else if (!(A instanceof Matrix)) {
        Backend.err.get().println("ERROR: Reopening file as a different resource type.");
        throw new Backend.AbortRun();
    }
    return (Matrix) A;
