All Implemented Interfaces:

IConstraints

public class ConstraintsGeneric

extends java.lang.Object

implements IConstraints

Implemention of the IConstraints interface used to specify search constraints on Jena statements. This implementation is suitable for any of the generic table layouts (whether hash or generator based) and should work for any reasonable database.

Constructor Summary

ConstraintsGeneric(ModelRDB model)
Constructor.

Method Summary

IConstraints	addIntConstraint(java.lang.String op, int constraint) Add a constraint that the object field should match the given integer literal using the sql comparison operator op - examples include "≥" and "≤=".
IConstraints	addObjectConstraint(Literal l) Add a constraint that the object field should match the given literal exactly
IConstraints	addObjectConstraint(Resource r) Add a constraint that the object field should match the given resource
IConstraints	addPropertyConstraint(Resource r) Add a constraint that the property field should match the given resource
IConstraints	addStringConstraint(java.lang.String op, java.lang.String constraint) Add a constraint that the object field should match the given string literal using the sql comparison operator op - such as "LIKE" or "NOT LIKE"
IConstraints	addSubjectConstraint(Resource r) Add a constraint that the subject field should match the given resource
IConstraints	reset() Clear all constraints
ResultSetIterator	runQuery(IRDBDriver driver, ModelRDB m) Execute the query implied by this set of constraints against the statements in the given model.
