Methods (Including Private)

private method %LoadData(id As %String) as %Status
Inherited description: %LoadData() - loads an object from storage. This method is implemented by the storage class.
classmethod GetOpenTx(Job As %Integer, ByRef TxInfo As %String) as %Status
Returns the job number of successive processes with open transactions.
classmethod GetTxJrnSize(tjrncnt As %Integer, tjrnoff As %Integer, ByRef tjrnbytes As %Integer) as %Status
Returns the number of bytes from starting journal file offset to current journal file offset.
classmethod GetTxJrnTime(tjrncnt As %Integer, tjrnoff As %Integer, ByRef timestamp As %Integer) as %Status
Returns the timestamp on the txstart record at journal file index and journal file offset.
classmethod GetVirtualLocation() as %String
