---------------------------------------
Summary: Change Interpolation interface to an abstract class
Key: SIS-530
URL: https://issues.apache.org/jira/browse/SIS-530
Project: Spatial Information Systems
Issue Type: Task
Components: Coverage
Affects Versions: 1.1
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
Fix For: 1.2
{{org.apache.sis.image.Interpolation}} is currently an interface. There is some
benefits to make it an abstract class instead. It would allow the addition of a
package-private method for handling special cases that we do not want to expose
in public API (those special cases are needed for resolving some exceptions
observed with {{Visualization}}). Another potential (but not verified) benefit
is a potential performance gain. The {{Interpolation.interpolate(…)}} method
can be invoked million of times for each image, and benchmarks report [slightly
faster method calls on abstract classes compared to
interfaces|https://coderedirect.com/questions/200341/performance-difference-between-passing-interface-and-class-reloaded].
