Examples of org.apache.drill.exec.vector.ValueVector

org.apache.drill.exec.vector.ValueVector
ValueVectorTypes defines a set of template-generated classes which implement type-specific value vectors. The template approach was chosen due to the lack of multiple inheritence. It is also important that all related logic be as efficient as possible.
