Example 11 with Scalar

use of org.apache.sysml.udf.Scalar in project systemml by apache.

the class DynamicReadMatrixRcCP method execute.

@Override

        _rc = new Scalar(ScalarValueType.Integer, "0");
    // NOTE: The packagesupport wrapper creates a new MatrixObjectNew with the given
    // matrix block. This leads to a dirty state of the new object. Hence, the resulting
    // intermediate plan variable will be exported in front of MR jobs and during this export
    // the format will be changed to binary block (the contract of external functions),
    // no matter in which format the original matrix was.

        _rc = new Scalar(ScalarValueType.Integer, "1");
    // throw new PackageRuntimeException("Error executing dynamic read of matrix",e);
