Examples of org.apache.drill.exec.vector.UInt4Vector$Mutator

org.apache.drill.exec.vector.UInt4Vector
UInt4.Mutator implements a mutable vector of fixed width values. Elements in the vector are accessed by position from the logical start of the vector. Values should be pushed onto the vector sequentially, but may be randomly accessed. The width of each element is 4 byte(s) The equivalent Java primitive is 'int' NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.

    defBuilder
        .setMajorType(typeBuilder.build());
        MaterializedField field = MaterializedField.create(defBuilder.build());


    // Create a new value vector for 1024 integers
    UInt4Vector v = new UInt4Vector(field, allocator);
    UInt4Vector.Mutator m = v.getMutator();
    v.allocateNew(1024);


    // Put and set a few values
    m.set(0, 100);
    m.set(1, 101);
    m.set(100, 102);
    m.set(1022, 103);
    m.set(1023, 104);
    assertEquals(100, v.getAccessor().get(0));
    assertEquals(101, v.getAccessor().get(1));
    assertEquals(102, v.getAccessor().get(100));
    assertEquals(103, v.getAccessor().get(1022));
    assertEquals(104, v.getAccessor().get(1023));


    // Ensure unallocated space returns 0
    assertEquals(0, v.getAccessor().get(3));
