CdbStatus hint (BdbRefAny &theHint, const CdbConditionPtr &theConditionPtr, const BdbTime &theBegin, const BdbTime &theEnd)
 Provide a placement hint in specified context.

CdbStatus verify (const BdbRefAny &theHint, const BdbHandle(BdbObject)&thePersObj, const CdbConditionPtr &theConditionPtr)
 Verify if specified placement hint and persistent objects match each other.

CdbStatus object (CdbObjectPtr &theObjectPtr, const CdbConditionPtr &theConditionPtr, const BdbTime &theBeginOriginalValidity, const BdbTime &theEndOriginalValidity, const BdbTime &theBeginValidity, const BdbTime &theEndValidity, const BdbTime &theBeginDuration, const BdbTime &theEndDuration, const BdbTime &theInsertionTime, const BdbHandle(BdbObject)&thePersObj)

Detailed Description

This is a trait class for creating objects.

This trait class provides object hint/creation/verification services to CDB API implementaions related to the current persistent technology.

The interface defines the following operations:

CdbStatus CdbBdbObjectCreator::hint (  BdbRefAny &    theHint,
const CdbConditionPtr &    theConditionPtr,
const BdbTime &    theBegin,
const BdbTime &    theEnd
)  [static]
 

Provide a placement hint in specified context.

This operation may involves interactions with a database.

theConditionPtr  a smart pointer onto a condition's API
theBeginOriginalValidity  a point where the object's 'original' validity begins from
theEndOriginalValidity  ... and finishes (exclusing) at
theBeginValidity  a point where the object's 'visible' validity begins from
theEndValidity  ... and finishes (exclusing) at
theBeginDuration  a point where the object's duration at insertin time begins from
theEndDuration  ... and finishes (exclusing) at
theInsertionTime  the time when a new object was created
thePersObj  a reference onto a persistent object

CdbStatus CdbBdbObjectCreator::verify (  const BdbRefAny &    theHint,
const BdbHandle(BdbObject)&    thePersObj,
const CdbConditionPtr &    theConditionPtr
)  [static]
 

Verify if specified placement hint and persistent objects match each other.

This operation is meant to verify of specified persistent object was properly created in the place suggested by the hint.

This operation may involves interactions with a database.

Parameters:
theHint  a reference to the hint
thePersObj  a reference onto a persistent object
theConditionPtr  a smart pointer onto a condition's API
