Method Detail

getObjectStatementList

public StatementList getObjectStatementList()

Specified by:

getObjectStatementList in interface ValueNode

getObjectStatements

public StatementIterator getObjectStatements()

Gets the list of Statements for which this LiteralNode is the object.

Specified by:

getObjectStatements in interface Value

Overrides:

getObjectStatements in class LiteralImpl

Returns:

A List of Statements, or null if no such statement exists.

getObjectStatementCount

public int getObjectStatementCount()

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

Specified by:

getObjectStatementCount in interface ValueNode

Returns:

An integer larger than or equal to 0.

addObjectStatement

public void addObjectStatement(Statement st)

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

Specified by:

addObjectStatement in interface ValueNode

removeObjectStatement

public void removeObjectStatement(Statement st)

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

Specified by:

removeObjectStatement in interface ValueNode

getRdfSource

public RdfSource getRdfSource()

Description copied from interface: ValueNode

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.

Specified by:

getRdfSource in interface ValueNode
