Method Details

getOIndexSearchResult

public OIndexSearchResult getOIndexSearchResult(OClass iSchemaClass,
 OSQLFilterCondition iCondition,
 List<OIndexSearchResult> iIndexSearchResults,
 OCommandContext context)

Overrides:

getOIndexSearchResult in class OQueryOperator

evaluateRecord

public Object evaluateRecord(OIdentifiable iRecord,
 ODocument iCurrentResult,
 OSQLFilterCondition iCondition,
 Object iLeft,
 Object iRight,
 OCommandContext iContext,
 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.

getBeginRidRange

public ORID getBeginRidRange(Object iLeft,
 Object iRight)

Specified by:

getBeginRidRange in class OQueryOperator

getEndRidRange

public ORID getEndRidRange(Object iLeft,
 Object iRight)

Specified by:

getEndRidRange in class OQueryOperator
