getField
public Field getField()
getIndex
public int getIndex()
The index of this Field in the array made of the concatenation of the
tuples from the children QueryTrees.
This is required here, since a FieldOperand does not have to be built
on a PropagatedField. In other words, the Field associated to this
FieldOperand may not be projected in the result of the operation.
setField
public void setField(Field f)
setIndex
public void setIndex(int idx)
