+--diva.sketch.parser2d.BasicConstraint
- public class BasicConstraint
- extends java.lang.Object
- implements RelationConstraint
An object that returns whether a pair of rectangles satisfies
constraints on the values of a specified relation. Constraints are
specified as a range from minimum to maximum value, inclusive.
Constants NO_MIN_CONSTRAINT and NO_MAX_CONSTRAINT are used to
specify an open range in either or both directions.

Field Summary |
static double |
NO_MAX_CONSTRAINT
Use this constant to specify no maximum constraint
for a particular relation. |
static double |
NO_MIN_CONSTRAINT
Use this to constant specify no minimum constraint
for a particular relation. |
Constructor Summary |
BasicConstraint(Relation r,
double minVal,
double maxVal)
Create the constraints object with the given relations and
given min/max constraints. |

NO_MAX_CONSTRAINT
public static double NO_MAX_CONSTRAINT
- Use this constant to specify no maximum constraint
for a particular relation.
NO_MIN_CONSTRAINT
public static double NO_MIN_CONSTRAINT
- Use this to constant specify no minimum constraint
for a particular relation.
BasicConstraint
public BasicConstraint(Relation r,
double minVal,
double maxVal)
- Create the constraints object with the given relations and
given min/max constraints. The relations will be applied
sequentially in the order given, so put the cheaper ones
or the more discriminatory ones first in the input.
debug
public static void debug(java.lang.String s)
- Debugging output.
parseMinMax
public static double parseMinMax(java.lang.String s)
- Parse a number string, NO_MIN, or NO_MAX into the corresponding
range boundary.
printMinMax
public static java.lang.String printMinMax(double d)
- Parse a number string, NO_MIN, or NO_MAX into the corresponding
range boundary.
test
public boolean test(java.awt.geom.Rectangle2D r1,
java.awt.geom.Rectangle2D r2)
- Test the constraints on the given rectangles; return true if
all constraints are met, false otherwise.
- Specified by:
- test in interface RelationConstraint
toString
public java.lang.String toString()
- Print out the contents of this constraint.
- Overrides:
- toString in class java.lang.Object
