List of constrain() Examples

Examples of constrain()

ae.sun.java2d.SunGraphics2D.constrain()
Constrain rendering for lightweight objects. REMIND: This method will back off to the "workaround" of using translate and clipRect if the Graphics to be constrained has a complex transform. The drawback of the workaround is that the resulting clip and device origin cannot be "enforced". @exception IllegalStateException If the Graphicsto be constrained has a complex transform.
com.db4o.query.Query.constrain()
adds a constraint to this node.

If the constraint contains attributes that are not yet present in the query graph, the query graph is extended accordingly.

Special behaviour for:
- class {@link Class}: confine the result to objects of one class or to objects implementing an interface.
- interface {@link Evaluation}: run evaluation callbacks against all candidates.
@param constraint the constraint to be added to this Query. @return {@link Constraint} a new {@link Constraint} for thisquery node or null for objects implementing the {@link Evaluation} interface.
com.mobixess.jodb.soda.api.Query.constrain()
adds a constraint to this node.

If the constraint contains attributes that are not yet present in the query graph, the query graph is extended accordingly.

Special behaviour for:
- class {@link Class}: confine the result to objects of one class (if the {@link Class} object represents a class)or to objects implementing a specific interface (if the {@link Class} object represents an interface).
- interface {@link Evaluation}: run evaluation callbacks against all candidates.
@param constraint the constraint to be added to this Query. @return {@link Constraint} a new {@link Constraint} for thisquery node or null for objects implementing the {@link Evaluation} interface.
org.jfree.data.Range.constrain()
Returns the value within the range that is closest to the specified value. @param value the value. @return The constrained value.
org.odbms.Query.constrain()
adds a constraint to this node.
If the object parameter is deeper than the entire query graph, the query graph is extended accordingly. @param example object for comparison @return Constraint
