insertTransactionDeletedObjID()

int glo::TransactionIndexPool::insertTransactionDeletedObjID	(	const std::string &	rsSchemaName,
		const ObjID &	rDeletedObjId )

Registers passed object ID in the current transaction for a schema index as deleted (increments the deletion counter, see also DeletedObjIdTuple::m_iDelCounter ).

Parameters

[in]	rsSchemaName	The schema name (e.g. "MyGloBase") to identify the SchemaIndex.
[in]	rDeletedObjId	The object ID to be registered as deleted.

Returns

A return value < 0 indicates an error.

Note

This method blocks further calls of methods of this class, which are secured with m_LocalCriticalSection.

TransactionIndexPool & glo::TransactionIndexPool::operator=

(

const IndexPool &

rT

)

Assignment operator.

Parameters

[in]

rT

removeTransactionDeletedObjID()

int glo::TransactionIndexPool::removeTransactionDeletedObjID	(	const std::string &	rsSchemaName,
		const ObjID &	rDeletedObjId )

Deregisters passed object ID for the current transaction for a schema index as deleted. (decrements the deletion counter, see also DeletedObjIdTuple::m_iDelCounter).

Parameters

[in]	rsSchemaName	The schema name (e.g. "MyGloBase") to identify the SchemaIndex.
[in]	rDeletedObjId	The object ID to be deregistered as deleted.

Returns

A return value < 0 indicates an error.

Note

This method blocks further calls of methods of this class, which are secured with m_LocalCriticalSection.
