Method Detail

getObjectStatementList

public StatementList getObjectStatementList()

getObjectStatementCount

public int getObjectStatementCount()

Gets the amount of Statements for which this ValueNode is the object.

Returns:

An integer larger than or equal to 0.

addObjectStatement

public void addObjectStatement(Statement st)

Adds a statement to this ValueNode's list of statements for which it is the object.

removeObjectStatement

public void removeObjectStatement(Statement st)

Removes a statement from this ValueNode's list of statements for which it is the object.

getRdfSource

public RdfSource getRdfSource()

Returns the RdfSource that contains this ValueNode. ValueNodes are only unique within a single repository, but an application could use several repository at the same time, passing ValueNodes generated by one Sail to another Sail. In such situations, the ValueNode of the first Sail cannot be used by the second Sail.
