Method Detail

constraint

public static Constraint constraint(Expression theExpression)

Create an integrity constraint from an OWL Axiom.

Parameters:

theExpression - the constraint axiom

Returns:

the new IC

constraint

public static Constraint constraint(Graph theGraph)

Create an integrity constraint from a Graph. The contents of the graph must be a single OWL axiom.

Parameters:

theGraph - the axiom graph.

Returns:

the new IC

Throws:

IllegalArgumentException - if the graph does not contain a single owl axiom, or contains more than one.

constraint

public static Constraint constraint(Collection<Statement> theStatements)

Create an integrity constraint from a collection of statements. The statements must be equal to a single OWL axiom.

Parameters:

theStatements - the axiom as statements

Returns:

the new IC

Throws:

IllegalArgumentException - if the graph of the statements does not contain a single owl axiom, or contains more than one.

constraints

public static Set<Constraint> constraints(Graph theGraph)

Create a set of integrity constraints from a Graph.

constraints

public static Set<Constraint> constraints(Collection<Statement> theStatements)

Create a set of integrity constraints from a collection of statements.

constraint

public static Constraint constraint(String theQuery)
                             throws StardogException

integrity constraint from the SPARQL query. The query should return a result when there is a violation and can only be a select query.

Parameters:

theQuery - the IC query

Returns:

the constraint

Throws:

StardogException - if the query was malformed or is not a select query
