public abstract class InequalityConstraintScaling extends Object
|Modifier||Constructor and Description|
Initializes a new instance.
|Modifier and Type||Method and Description|
Indicates whether some other object is "equal to" this one.
Returns a hash code value for the object.
Gets the scaling value as it would be applied to the constraint.
public abstract double scale(@Nonnull InequalityConstraintSettings settings)
InequalityConstraintSettingsto which this scaling will apply.

equals method for class
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values
y, this method returns
true if and only
y refer to the same object
x == y has the value
Note that it is generally necessary to override the
method whenever this method is overridden, so as to maintain the
general contract for the
hashCode method, which states
that equal objects must have equal hash codes.

The general contract of

equalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
equals(Object)method, then calling the
hashCodemethod on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)method, then calling the
hashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
Java™ programming language.)
