Inspired by http://www.w3.org/2001/12/rubyrdf/basicrdf.rb

An interface for Graph objects

Method Summary

java.util.Vector	ask(java.lang.Object s, java.lang.Object p, java.lang.Object o) Return a Graph matching the query triple specified.
Graph	ask(Query query) Return a Graph matching the query triple specified.
java.sql.ResultSet	askSquish(java.lang.String query) Ask a squish query of any type of Graph returnign a rectangular ResultSet.
boolean	delete(Statement s) Delete a single statement (or all instances of a given Statement).
java.lang.String	getBase() Sets the base uri for the GraphInterface.
java.util.Vector	getStatements() Returns a Vector of all Statements in the GraphInterface
boolean	removeAll() Remove all statements.
void	setBase(java.lang.String base) Returns the base uri for the GraphInterface.
void	tell(Statement statement) Insert a single Statement into the GraphInterface
void	tellAll(java.util.Vector statements) Inserts all the Statements into a Vector into the GraphInterface

Method Detail

getStatements

public java.util.Vector getStatements()

Returns a Vector of all Statements in the GraphInterface

tellAll

public void tellAll(java.util.Vector statements)

Inserts all the Statements into a Vector into the GraphInterface

tell

public void tell(Statement statement)

Insert a single Statement into the GraphInterface

ask

public Graph ask(Query query)

Return a Graph matching the query triple specified. The Query can have null arguments.

ask

public java.util.Vector ask(java.lang.Object s,
                            java.lang.Object p,
                            java.lang.Object o)

Return a Graph matching the query triple specified. Arguments should be Strings, Nodes or null.

getBase

public java.lang.String getBase()

Sets the base uri for the GraphInterface. Usually this will be the url or filename of an RDF file. For UnionGraphs it is @@fixme@@; for SQLGraph it is the jdbc database url.

setBase

public void setBase(java.lang.String base)

Returns the base uri for the GraphInterface. Usually this will be the url or filename of an RDF file. For UnionGraphs it is @@fixme@@; for SQLGraph it is the jdbc database url.

askSquish

public java.sql.ResultSet askSquish(java.lang.String query)

Ask a squish query of any type of Graph returnign a rectangular ResultSet.

delete

public boolean delete(Statement s)

Delete a single statement (or all instances of a given Statement).

removeAll

public boolean removeAll()

Remove all statements.
