Field Details

key

public String key

A relative path (under the main shapes dir) or absolute path (for images elsewhere), case-sensitive and complete with the extension.

file

public final File file

For static objects, this is the SVG file for the image. For dynamically generated ones, null.

Constructor Details

ImageObject

protected ImageObject()

Used by Composite

Method Details

getKey

public String getKey()

getSvg

public String getSvg()

The SVG code for the image, if available. It is mandatory for dynamically generated ImageObjects (/composite). For static ones, it may or may not be null.

clearTable

public static void clearTable()

enlist

public void enlist()

Enters this ImageObject into the master table

obtainImageObjectPlain

public static ImageObject obtainImageObjectPlain(File dir,
 String plainPath,
 boolean allowMissing)

Retrieves the ImageObject for a specified path (no wildcards!) from the master table. If necessary, tries to add that object (and all other objects listed in the properties file in that directory) to the master table.

Parameters:

dir - If provided, plainPath is understood as being relative to it.

plainPath - The image path (relative to dir, or absolute if dir==null). Must not contain wildcards. May contain an extension (e.g. ".png" or ".svg"); if it does not, ".svg" will be added.

obtainImageObjectPlain

public static ImageObject obtainImageObjectPlain(File f)

obtainImageObjectPlain

public static ImageObject obtainImageObjectPlain(File f,
 boolean allowMissing)

Parameters:

allowMissing - If true, simply return null, rather than throw exception, when the file is not listed in the prop file

obtainImageObjects

public static Vector<ImageObject> obtainImageObjects(String wildCardPath)

Loads an image object (or a group of them, if a wildcard is given).

Parameters:

path - One of the values from the "images" column of ParaSet. It is either a path (maybe with wildcards) relative to game-data/shapes, or a /composite/... string refering to a dynamically generated Composite ImageObject (or a group of them).

Returns:

a Vector of "regular" ImageObjects (associated with the file(s) given by the wildCardPath), or a Composite ImageObject (maybe a "family" one) is the path is of that kind.

listProperties

public String listProperties()

listProperties

public String listProperties(String sep)

Produces a "key1:val1, key2:val2, ..." list, with a desired separator.

symbol

public String symbol()

For use in ASCII graphics
