Example 1 with ArrayWriter

use of org.apache.drill.exec.vector.accessor.ArrayWriter in project drill by apache.

the class TupleWriterImpl method setArray.

public void setArray(int colIndex, Object value) {
    if (value == null) {
        return;
    }
    String objClass = value.getClass().getName();
    if (!objClass.startsWith("[")) {
        throw new IllegalArgumentException("Argument is not an array");
    }
    ColumnWriter colWriter = column(colIndex);
    if (colWriter.valueType() != ValueType.ARRAY) {
        throw new IllegalArgumentException("Column is not an array");
    }
    ArrayWriter arrayWriter = colWriter.array();
    // Figure out type
    char second = objClass.charAt(1);
    switch(second) {
        case 'B':
            AccessorUtilities.setByteArray(arrayWriter, (byte[]) value);
            break;
        case 'S':
            AccessorUtilities.setShortArray(arrayWriter, (short[]) value);
            break;
        case 'I':
            AccessorUtilities.setIntArray(arrayWriter, (int[]) value);
            break;
        case 'J':
            AccessorUtilities.setLongArray(arrayWriter, (long[]) value);
            break;

        case 'Z':
            AccessorUtilities.setBooleanArray(arrayWriter, (boolean[]) value);
            break;
        case 'L':
            int posn = objClass.indexOf(';');
            // If the array is of type Object, then we have no type info.
            String memberClassName = objClass.substring(2, posn);
            if (memberClassName.equals(String.class.getName())) {
                AccessorUtilities.setStringArray(arrayWriter, (String[]) value);
            } else if (memberClassName.equals(Period.class.getName())) {
                AccessorUtilities.setPeriodArray(arrayWriter, (Period[]) value);
            } else if (memberClassName.equals(BigDecimal.class.getName())) {
                AccessorUtilities.setBigDecimalArray(arrayWriter, (BigDecimal[]) value);
            } else {
                throw new IllegalArgumentException("Unknown Java array type: " + memberClassName);
            }
            break;
        default:
            throw new IllegalArgumentException("Unknown Java array type: " + second);
    }
}

    RowSetReader reader = rs1.reader();
