                             ODocumentSerializer serializer)

Description copied from class: OQueryTargetOperator

At run-time the evaluation per record must return always true since the recordset are filtered at the beginning unless an operator can work in both modes. In this case sub-class must extend it.

Overrides:

evaluateRecord in class OQueryTargetOperator

getIndexReuseType

public OIndexReuseType getIndexReuseType(Object iLeft,
                                         Object iRight)

Description copied from class: OQueryOperator

Returns hint how index can be used to calculate result of operator execution.

Specified by:

getIndexReuseType in class OQueryOperator

Parameters:

iLeft - Value of left query parameter.

iRight - Value of right query parameter.

Returns:

Hint how index can be used to calculate result of operator execution.

getEndRidRange

public ORID getEndRidRange(Object iLeft,
                           Object iRight)
