Examples of Area

ae.java.awt.geom.Area
An Area object stores and manipulates a resolution-independent description of an enclosed area of 2-dimensional space. Area objects can be transformed and can perform various Constructive Area Geometry (CAG) operations when combined with other Area objects. The CAG operations include area {@link #add addition}, {@link #subtract subtraction}, {@link #intersect intersection}, and {@link #exclusiveOr exclusive or}. See the linked method documentation for examples of the various operations.
The Area class implements the Shape interface and provides full support for all of its hit-testing and path iteration facilities, but an Area is more specific than a generalized path in a number of ways:
- Only closed paths and sub-paths are stored. Area objects constructed from unclosed paths are implicitly closed during construction as if those paths had been filled by the Graphics2D.fill method.
- The interiors of the individual stored sub-paths are all non-empty and non-overlapping. Paths are decomposed during construction into separate component non-overlapping parts, empty pieces of the path are discarded, and then these non-empty and non-overlapping properties are maintained through all subsequent CAG operations. Outlines of different component sub-paths may touch each other, as long as they do not cross so that their enclosed areas overlap.
- The geometry of the path describing the outline of the Area resembles the path from which it was constructed only in that it describes the same enclosed 2-dimensional area, but may use entirely different types and ordering of the path segments to do so.
Interesting issues which are not always obvious when using the Area include:
- Creating an Area from an unclosed (open) Shape results in a closed outline in the Area object.
- Creating an Area from a Shape which encloses no area (even when "closed") produces an empty Area. A common example of this issue is that producing an Area from a line will be empty since the line encloses no area. An empty Area will iterate no geometry in its PathIterator objects.
- A self-intersecting Shape may be split into two (or more) sub-paths each enclosing one of the non-intersecting portions of the original path.
- An Area may take more path segments to describe the same geometry even when the original outline is simple and obvious. The analysis that the Area class must perform on the path may not reflect the same concepts of "simple and obvious" as a human being perceives.

@author kailashThe main intention in Chain Of Responsibility is to decouple the origin of the request and handling of the request such that the origin of the request need not worry who and how its request is being handled as long as it gets the expected outcome. By decoupling the origin of the request and the request handler we make sure that both can change easily and new request handlers can be added without the origin of the request i.e client being aware of the changes. In this pattern we create a chain of objects such that each object will have a reference to another object which we call it as successor and these objects are responsible for handling the request from the client. All the objects which are part of the chain are created from classes which confirm to a common interface there by the client only needs to be aware of the interface and not necessarily the types of its implementations. The client assigns the request to first object part of the chain and the chain is created in such a way that there would be at least one object which can handle the request or the client would be made aware of the fact that its request couldn�t be handled.
