Class RoverImageFile

java.lang.Object

com.partnersoft.maps.rover.RoverImageFile

All Implemented Interfaces:

Identifiable

public class RoverImageFile
extends java.lang.Object
implements Identifiable

A named image file, including byte contents.

This is an abstraction of an image file. It may or may not actually be loaded from a filesystem; that is up to the RoverStore implementation.

The distinction between this and RoverImage is that a RoverImage is an image placed on the map, with only a pointer to the RoverImageFile, which contains the contents.

Method Detail

withId

public RoverImageFile withId(int id)

getGuid

public java.lang.String getGuid()

Description copied from interface: Identifiable

Globally-unique ID (GUID) for this object. GUIDs should be globally unique for all of a specific kind of identifiable - in fact they should generally follow the UUID design and be unique for all things in the universe. They are used for synchronization in long-transaction, multiple-machine systems. GUIDs are represented as a single String; this interface does not require a required format. GUIDs are generally too long to be very human-legible.

Specified by:

getGuid in interface Identifiable

getId

public int getId()

Description copied from interface: Identifiable

Numeric ID for this object. Numeric IDs may only be unique for a set of Identifiables in a specific context (e.g. a single computer or database). They are generally small enough to be human-legible but may be automatically generated (e.g. auto incremented).

Specified by:

getId in interface Identifiable

getName

public java.lang.String getName()

Description copied from interface: Identifiable

Name of this object. Names may not be unique for any given set of Identifiables. They are generally human-oriented.

Specified by:

getName in interface Identifiable

getContents

public byte[] getContents()

createImage

public java.awt.Image createImage()
