public class Cramfull
extends java.util.ResourceBundle

The abstract class Cramfull is a framework for it's subclasses to encapsulate resources in their .class-file itself. These subclasses are not coded by the application programmer, but generated and compiled by a ClassCompiler.

Being also a subclass of ResourceBundle, a generated Cramfull subclass MyCramfull can either be instantiated individualy and directly by invoking the no-args constructor as new MyCramfull() or as Class.forName("MyCramfull").newInstance(), or either be organized into a Locale hierarchy by a invoking ResourceBundle.getBundle("MyCramfull", someLocale). When loading a locale hierarchy through ResourceBundle.getBundle(), Cramfull subclasses should not be mixed with other ResourceBundle implementations; all extra functionality stops at the first non-Cramfull ResourceBundle. See java.util.ResourceBundle for more information about resource bundles in general.

Getter Methods
Cramfull offers a set of getter methods that should be used in preference to ResourceBundle.getObject(String). These getter methods retrieve resources as a byte[], as a java.io.InputStream, or as a deserialized Object, but also as the commonly used types java.awt.Image, java.applet.AudioClip and java.util.Properties. Cramfull subclasses that are organized in a locale hierarchy by ResourceBundle.getBundle("MyCramfull") can even restore a .properties file hierarchy from the contained resources in the same way as ResourceBundle.getBundle("MyProperties") would have done from the file system.

Because speed and memory usage are important when managing lots of resources, the getter methods have a retention option to enable caching a resource in the retrieved type after decoding, or removing the reference to the resource from the Cramfull that contains it. Both options enable garbage collection of the encoded resource data.

Note: Cramfull is a subclass of java.util.ResourceBundle to exploit the facilities for loading locale hierarchies. However, the following methods, which we cannot override because they are final, should not be invoked. They will either throw a typecasting error or give access to encoded resource data only:

Note: With be.arci.pub.ResourceViewer we provide a utility to view the resources contained in a Cramfull subclass. With be.arci.pub.ResourceViewer you can also list the names of these resources to the console, or extract them as normal files again.

Constructor Detail

Cramfull

protected Cramfull(java.util.Hashtable htResources)
Initializes a Cramfull subclass with a set of key-value pairs. Each key of htResources is a resourcename, while each value is the resource data in encoded form.
Method Detail

guessMIMETypeFromName

public static java.lang.String guessMIMETypeFromName(java.lang.String sResource)
Tries to determine the content type of a resource, based on it's name. This is a convenience method that can be used before calling one of the getter methods.

REMARK: We guess that normally the application programmer will know what the type of his resources is; this method's purpose is mainly for use by utility classes like be.arci.pub.ResourceViewer.

Note:This implementation builds on java.net.URLConntection.guessContentTypeFromName(); in some earlier JVM's this method always returns "unknown/unknown". For a list of available content types, look for files like "content-types.properties" in Sun's standard JDK distribution.

Parameters:
sResource - the (file) name of a resource
Returns:
a guess as to what the content type of the object is, based upon its file name; "unknown/unknown" if java.net.URLConntection cannot determine the content type from the resource name.
See Also:
"java.net.URLConnection.guessContentTypeFromName(String)",
guessMIMEType(String sResource)

setAudioClipCandidates

public static void setAudioClipCandidates(java.lang.String[] asAudioClipClass)
Sets the possible java.applet.AudioClip implementations to search for. The getAudioClip methods load audio resources using the first of these classes that is found and has an accessible constructor from InputStream.

Rationale: Standard Java classes can only load audioclip resources from an URL (in JDK1.1 applications, there is even no standard Java class that can load audioclip resources). In browser JVM-s we cannot define new URL protocols for opening an URL on a resource in a Cramfull subclass. Hence we have to trie diferent java.applet.AudioClip implementations to load audio resources. The current java.applet.AudioClip implementations are (in the order they are tried)

  1. "com.sun.media.sound.JavaSoundAudioClip",
  2. "sun.audio.SunAudioClip",
  3. "be.arci.applet.FallbackAudioClip"
As other implementations become available, you might prefer one or the other to try first.

Parameters:
asAudioClipClass - qualified Java class names of java.applet.AudioClip implementations to search for.
See Also:

getAudioClip(String sResource)

getLocaleSuffix

public java.lang.String getLocaleSuffix()
Tries to get the locale of a Cramfull subclass by calling the Java2-added method ResourceBundle.getLocale(). This call can fail, either because the Cramfull subclass was not loaded by ResourceBundle.getBundle() or because the JVM is at Java 1.1.x level. In that case the method defines the locale suffix as the suffix of the Cramfull subclass-name after and including the first '_' char of the class-name (ignoring an eventual leading '_' char in the class-name). If no such suffix is found, an empty String is returned.

Example:
MyCramfull_nl_BE would give the locale suffix "_nl_BE".

Returns:
the locale suffix of this Cramfull subclass.
See Also:
getLocaleSuffix(String sResource)

getLocaleSuffix

public java.lang.String getLocaleSuffix(java.lang.String sResource)
Returns the locale suffix of the first Cramfull subclass in the locale hierarchy obtained by java.util.ResourceBundle.getBundle() that contains the named resource.
Parameters:
sResource - the resource name
Returns:
the locale suffix of the first Cramfull subclass in this locale hierarchy that contains the named resource.
See Also:
getLocaleSuffix()

handleGetObject

protected final java.lang.Object handleGetObject(java.lang.String sResource)
Retrieves the named resource from this Cramfull's set of compiled resources, in it's encoded or cached form.

REMARK: This method is protected for access by java.util.ResourceBundle only. Application programmers could invoke getObject(String) instead; we recommend however to invoke the getter methods instead.

Overrides:
handleGetObject in class java.util.ResourceBundle
See Also:
"java.util.ResourceBundle.getObject(String)",
getByteArray(String sResource),
getInputStream(String sResource),
getDeserialized(String sResource),
getProperties(String sResource),
getLocalizedProperties(String sResource),
getImage(String sResource),
getAudioClip(String sResource)

getKeys

public java.util.Enumeration getKeys()
Implementation of ResourceBundle.getKeys(). If this Cramfull is obtained by ResourceBundle.getBundle(), the returned Enumeration runs over this Cramfull and all it's parents, else over this Cramfull only.

While enumerating, retrieving resources via the getter methods with any other retention than RET_ENCODED will disturb the enumeration, as the underlying collection is changed by caching or removing resources.

Overrides:
getKeys in class java.util.ResourceBundle
Returns:
an Enumeration over this Cramfull's resource names and those of it's parents.

RET_ENCODED,
getByteArray(String sResource, int iRetention),
getInputStream(String sResource, int iRetention),

guessMIMEType

public java.lang.String guessMIMEType(java.lang.String sResource)
                               throws java.util.MissingResourceException,
                                      ResourceDecodingException
Tries to determine the content type of a resource, based on it's decoded data. This is a convenience method that can be used before calling one of the getter methods.

REMARK: We guess that normally the application programmer will know what the type of his resources is; this method's purpose is mainly for use by utility classes like be.arci.pub.ResourceViewer.

If the resource is cached as Image or AudioClip object, this method will try to delegate to guessMIMETypeFromName. If that does not return an "image/..." or "audio/..." type respectively, the type "image/unknown" or "audio/unknown" is returned, without determining the exact subtype. If the resource is cached as deserialized Object, and guessMIMETypeFromName does not return a "application/..." type, the type "application/octet-stream" is returned. If the resource is cached as Properties object, and guessMIMETypeFromName does not return a "text/..." type, the self-defined type "text/properties" is returned.

If the resource is cached as InputStream, that InputStream will be reset during this call and in the next call to getInputStream().

Parameters:
sResource - the name of a resource.
Returns:
a best guess of the content type of the named resource, based upon its content data and it's name. This method returns "content/unknown" if the resource is found, but it's content type cannot be determined.

guessMIMETypeFromName(String sResource)

                                          ResourceDecodingException
Returns a java.util.Properties object loaded from the named resource's data.

Note: (from java.util.Properties documentation)
When loading properties from a resource, the ISO 8859-1 character encoding is used (ISO 8859-1 is also known as the Latin 1 or ANSI character set). For characters that cannot be directly represented in this encoding, Unicode escapes should be used; however, only a single 'u' character is allowed in an escape sequence. JDK's native2ascii tool can be used to convert the original .properties-files from other character encodings.

Parameters:
sResource - the resource name
Returns:
java.util.Properties object loaded from the resource's decoded data.

For characters that cannot be directly represented in this encoding, Unicode escapes should be used; however, only a single 'u' character is allowed in an escape sequence. JDK's native2ascii tool can be used to convert the original .properties-files from other character encodings.

    Parameters:
    sBasename - the basename for the resource hierarchy; if this name has no .properties suffix, that will be appended.
    iRetention - the retention option; allows optimization of memory usage and retrieval time for repeated retrieval. This method is the only one for which the retention code RET_CACHE_ALL is allowed: the resource and each of it's localized parents in their containing Cramfull subclass will be loaded in a Properties object and cached in their respective Cramfull subclass.
    Returns:
    Properties object loaded from the resource's decoded data.

    getImage

    public java.awt.Image getImage(java.lang.String sResource)
                        throws java.util.MissingResourceException,
                               ResourceDecodingException
    Returns an Image object created from the named resource's data.

    This method creates an image from the resource data using Toolkit.getDefaultToolkit().createImage(). Toolkit.createImage() need not load the data before returning, nor check it to be valid image data. Hence the return value can be non-null, even if the named resource is not an image file.

    Parameters:
    sResource - the resource name
    Returns:
    Image object loaded from the resource's decoded data.

    getAudioClip

    public java.applet.AudioClip getAudioClip(java.lang.String sResource)
                                   throws java.util.MissingResourceException,
                                          ResourceDecodingException
    Returns an AudioClip object created from the named resource's data.

    Parameters:
    sResource - the resource name
    Returns:
    AudioClip object loaded from the resource's decoded data.

                                          ResourceDecodingException
    Returns an AudioClip object loaded from the named resource's data.

    Parameters:
    sResource - the resource name
    iRetention - the retention option; allows optimization of memory usage and retrieval time for repeated retrieval
    Returns:
    AudioClip object loaded from the resource's decoded data.

    remove

    public void remove(java.lang.String sResource,
                   boolean swRecursive)
    Remove the reference to the named resource from this Cramfull subclass or the first parent in the locale hierarchy that contains the resource.

    Note: In current JVM's the memory saving of removing an encoded resource is not visible in the return value of Runtime.getRuntime().freeMemory(): as that method seems not to report about memory taken by all class constants. But the memory saving is not less real.

    Parameters:
    sResource - the resource to remove of
    swRecursive - if true, the reference to this resource is removed from the containing Cramfull subclass and it's parents (as loaded through java.util.ResourceBundle.getBundle()).
