creator
- The object that is creating this MemLiteral.label
- The label for this literal.
-
MemLiteral
public MemLiteral(Object creator, String label, String lang)

Method Detail
-
getCreator
public Object getCreator()
Description copied from interface:MemValue
Returns 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:
getCreator
in interfaceMemValue
-
hasStatements
public boolean hasStatements()
Description copied from interface:MemValue
Checks 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:
hasStatements
in interfaceMemValue
- Returns:
- true if the MemValue has statements, false otherwise.
-
getObjectStatementList
public MemStatementList getObjectStatementList()
Description copied from interface:MemValue
Gets the list of statements for which this MemValue is the object.- Specified by:
getObjectStatementList
in interfaceMemValue
- Returns:
- A MemStatementList containing the statements.
-
getObjectStatementCount
public int getObjectStatementCount()
Description copied from interface:MemValue
Gets the number of statements for which this MemValue is the object.- Specified by:
getObjectStatementCount
in interfaceMemValue
- Returns:
- An integer larger than or equal to 0.
-
addObjectStatement
public void addObjectStatement(MemStatement st)
Description copied from interface:MemValue
Adds a statement to this MemValue's list of statements for which it is the object.- Specified by:
addObjectStatement
in interfaceMemValue
-
removeObjectStatement
public void removeObjectStatement(MemStatement st)
Description copied from interface:MemValue
Removes a statement from this MemValue's list of statements for which it is the object.- Specified by:
removeObjectStatement
in interfaceMemValue
-
cleanSnapshotsFromObjectStatements
public void cleanSnapshotsFromObjectStatements(int currentSnapshot)
Description copied from interface:MemValue
Removes 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:
cleanSnapshotsFromObjectStatements
in interfaceMemValue
- Parameters:
currentSnapshot
