Constructor Detail

BagConstraint

public BagConstraint(QueryNode qn,
                     ConstraintOp op,
                     java.util.Collection<?> bag)

Construct a BagConstraint from a Collection. Note that the bag isn't copied so it should not be changed after the Query has been executed. BagConstraint will accept ONE_OF and NONE_OF as constraint op arguments but will use corresponding IN and NOT_IN.

Parameters:

qn - the QueryNode to compare to the bag

op - the operation

bag - a Collection that represents the bag

public BagConstraint(QueryNode qn,
                     ConstraintOp op,
                     ObjectStoreBag osb)

Construct a BagConstraint from an ObjectStoreBag.

Parameters:

qn - the QueryNode to compare to the bag

op - the operation

osb - an ObjectStoreBag
