Method Detail

hasNext

public boolean hasNext()

getNumberOfDistinctProperties

public int getNumberOfDistinctProperties()

setNumberOfDistinctProperties

public void setNumberOfDistinctProperties(int theNumberOfDistinctProperties)

Sets the number of distinct properties to be used. If set to 0, completely random set of properties will be generated.

getNumberOfStatementsPerSubject

public int getNumberOfStatementsPerSubject()

setNumberOfStatementsPerSubject

public void setNumberOfStatementsPerSubject(int theNumberOfStatementsPerSubject)

Sets the number of statements to be generated for a given subject. Set to 0 to use completely random set of properties.

getNumberOfDistinctClasses

public int getNumberOfDistinctClasses()

setNumberOfDistinctClasses

public void setNumberOfDistinctClasses(int theNumberOfDistinctClasses)

Sets the number of distinct classes to be used as types. If set to 0, no rdf:type triples will be generated.

getNumberOfSubjectsPerGraph

public int getNumberOfSubjectsPerGraph()

setNumberOfSubjectsPerGraph

public void setNumberOfSubjectsPerGraph(int theNumberOfSubjectsPerGraph)

Sets the number of subjects generated per graph. Default is 0 which means no named graphs are generated. Set to Integer.MAX_VALUE to generate a single named graph.

next

public Statement next()

Returns the next random triple.

main

public static void main(java.lang.String[] args)
