AndPredicate

public AndPredicate(List<StarPredicate> predicateList)

Method Detail

evaluate

public boolean evaluate(List<Object> valueList)

Description copied from interface: StarPredicate

Evaluates a constraint against a list of values.

If one of the values is StarPredicate.WILDCARD, returns true if constraint is true for all possible values of that column.

Parameters:

valueList - List of values, one for each constrained column

Returns:

Whether constraint holds for given set of values

and

public StarPredicate and(StarPredicate predicate)

Description copied from interface: StarPredicate

Returns this intersection of this Predicate with another. The result is a Predicate which holds whenever both predicates hold.

Parameters:

predicate - Predicate

Returns:

Combined predicate

or

public StarPredicate or(StarPredicate predicate)

Description copied from interface: StarPredicate

Returns this union of this Predicate with another. The result is a Predicate which holds whenever either predicate holds.

Parameters:

predicate - Predicate

Returns:

Combined predicate

checkInList

public BitKey checkInList(SqlQuery sqlQuery,
                          BitKey inListLHSBitKey)

toInListSql

public void toInListSql(SqlQuery sqlQuery,
                        StringBuilder buf,
                        BitKey inListRHSBitKey)

Generate value list for this predicate to be used in an IN-list sql predicate. The values in a multi-column IN list predicates are generated in the same order, based on the bit position from the columnBitKey.

getOp

protected String getOp()

Specified by:

getOp in class ListPredicate
