Uses of Constraint in com.db4o.query

Subinterfaces of Constraint in com.db4o.query

Modifier and Type	Interface	Description
interface	Constraints	A set of Constraint objects.

Methods in com.db4o.query that return Constraint

Modifier and Type	Method	Description
Constraint	Constraint.and(Constraint with)	Links two Constraints for AND evaluation.
Constraint	Constraint.byExample()	Set the evaluation mode to object comparison (query by example).
Constraint	Query.constrain(java.lang.Object constraint)	Adds a constraint to this node.
Constraint	Constraint.contains()	Sets the evaluation mode to string contains comparison.
Constraint	Constraint.endsWith(boolean caseSensitive)	Sets the evaluation mode to string endsWith comparison.
Constraint	Constraint.equal()	Used in conjunction with smaller() or greater() to create constraints like "smaller or equal", "greater or equal".
Constraint	Constraint.greater()	Sets the evaluation mode to >.
Constraint	Constraint.identity()	Sets the evaluation mode to identity comparison.
Constraint	Constraint.like()	Sets the evaluation mode to "like" comparison.
Constraint	Constraint.not()	Turns on not() comparison.
Constraint	Constraint.or(Constraint with)	Links two Constraints for OR evaluation.
Constraint	Constraint.smaller()	Sets the evaluation mode to <.
Constraint	Constraint.startsWith(boolean caseSensitive)	Sets the evaluation mode to string startsWith comparison.
