Method Summary

Modifier and Type	Method	Description
<T> Map<T,T>	scaleElements(List<T> elements, ScaleFactor scaleFactor, Optional<UnaryOperator<T>> preOperation, Optional<UnaryOperator<T>> postOperation, AccessObjectMask<T> access)	Applies a scaling factor to elements, where each element is associated with a unique ObjectMask.

Method Details

scaleElements

default <T> Map<T,T> scaleElements(List<T> elements,
 ScaleFactor scaleFactor,
 AccessObjectMask<T> access)
                            throws OperationFailedException

Applies a scaling factor to elements, where each element is associated with a unique ObjectMask.

Type Parameters:

T - the element-type, which must have a sensible Object.hashCode() and Object.equals(java.lang.Object) implementation.

Parameters:

elements - the collection of input elements, whose associated ObjectMasks will be scaled.

scaleFactor - how much to scale by.

access - means of retrieving the ObjectMask that is associated with T and to create new derived elements.

Returns:

a map from input-element (unscaled) to the corresponding output-element (scaled).

Throws:

OperationFailedException - if any aspect of the parameterization is unsupported by the method.

scaleElements

<T> Map<T,T> scaleElements(List<T> elements,
 ScaleFactor scaleFactor,
 Optional<UnaryOperator<T>> preOperation,
 Optional<UnaryOperator<T>> postOperation,
 AccessObjectMask<T> access)
                    throws OperationFailedException

Applies a scaling factor to elements, where each element is associated with a unique ObjectMask.

Type Parameters:

T - the element-type, which must have a sensible Object.hashCode() and Object.equals(java.lang.Object) implementation.

Parameters:

elements - the collection of input elements, whose associated ObjectMasks will be scaled.

scaleFactor - how much to scale by.

preOperation - an optional operation applied to an element before scaling.

postOperation - an optional operation applied to an element after scaling.

access - means of retrieving the ObjectMask that is associated with T and to create new derived elements.

Returns:

a map from input-element (unscaled) to the corresponding output-element (scaled).

Throws:

OperationFailedException - if any aspect of the parameterization is unsupported by the method.
