Method Detail

getField

public Field getField()

setField

public void setField(Field f)

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.


setIndex

public void setIndex(int idx)
