Example 26 with IntVector

use of org.apache.drill.exec.vector.IntVector in project drill by apache.

the class TestFixedWidthWriter method allocVector.

use of org.apache.drill.exec.vector.IntVector in project drill by apache.

the class TestFixedWidthWriter method testFillEmpties.

/**

 * than failing. (The SQL solution would be to fill with nulls, but a
