Method Detail
-
getCreator
public Object getCreator()
Description copied from interface:MemValueReturns the object that created this MemValue. MemValues are only unique within a single repository, but an application could use several repositories at the same time, passing MemValues generated by one Sail to another Sail. In such situations, the MemValue of the first Sail cannot be used by the second Sail.- Specified by:
getCreatorin interfaceMemValue
-
hasStatements
public boolean hasStatements()
Description copied from interface:MemValueChecks whether this MemValue has any statements. A MemValue object has statements if there is at least one statement where it is used as the subject, predicate, object or context value.- Specified by:
hasStatementsin interfaceMemValue- Returns:
- true if the MemValue has statements, false otherwise.
-
getObjectStatementList
public MemStatementList getObjectStatementList()
Description copied from interface:MemValueGets the list of statements for which this MemValue is the object.- Specified by:
getObjectStatementListin interfaceMemValue- Returns:
- A MemStatementList containing the statements.
-
getObjectStatementCount
public int getObjectStatementCount()
Description copied from interface:MemValueGets the number of statements for which this MemValue is the object.- Specified by:
getObjectStatementCountin interfaceMemValue- Returns:
- An integer larger than or equal to 0.
-
addObjectStatement
public void addObjectStatement(MemStatement st) throws InterruptedException
Description copied from interface:MemValueAdds a statement to this MemValue's list of statements for which it is the object.- Specified by:
addObjectStatementin interfaceMemValue- Throws:
InterruptedException
-
cleanSnapshotsFromObjectStatements
public void cleanSnapshotsFromObjectStatements(int currentSnapshot) throws InterruptedExceptionDescription copied from interface:MemValueRemoves statements from old snapshots (those that have expired at or before the specified snapshot version) from this MemValue's list of statements for which it is the object.- Specified by:
cleanSnapshotsFromObjectStatementsin interfaceMemValue- Parameters:
currentSnapshot- The current snapshot version.- Throws:
InterruptedException
