  +--oracle.cabo.image.encode.ImageEncoderManager

public class ImageEncoderManager

extends java.lang.Object

ImageEncoderManager maintains a registry of image encodings. Currently, clients must use the getDefaultImageEncoderManager() to obtain a reference to the single, shared ImageEncoderManager.

Field Summary

static java.lang.String	GIF_TYPE Mime type for GIF
static java.lang.String	PNG_TYPE Mime type for PNG

Method Summary

static ImageEncoderManager	getDefaultImageEncoderManager() Returns the default ImageEncoderManager
ImageEncoder	getImageEncoder(java.lang.String type) Returns the ImageEncoder for the specified encoding.
java.lang.String	getImageExtension(java.lang.String type) Returns the file extension for the specified type.
void	registerEncoding(java.lang.String type, java.lang.String extension, ImageEncoder encoder) Registers an encoding.
void	registerEncoding(java.lang.String type, java.lang.String extension, java.lang.String encoderClassName) Registers an encoding.
void	unregisterEncoding(java.lang.String type) Unregisters an encoding

Method Detail

getDefaultImageEncoderManager

public static ImageEncoderManager getDefaultImageEncoderManager()

Returns the default ImageEncoderManager

getImageEncoder

public ImageEncoder getImageEncoder(java.lang.String type)

Returns the ImageEncoder for the specified encoding.

Parameters:

type - The mime type for the encoding, eg. "image/gif".

getImageExtension

public java.lang.String getImageExtension(java.lang.String type)

Returns the file extension for the specified type.

Parameters:

type - The mime type for the encoding, eg. "image/gif".

registerEncoding

public void registerEncoding(java.lang.String type,
                             java.lang.String extension,
                             ImageEncoder encoder)

Registers an encoding.

Parameters:

type - The mime type of the encoding

extension - The file extension for the encoding

encoder - The ImageEncoder instance to use for this encoding

registerEncoding

public void registerEncoding(java.lang.String type,
                             java.lang.String extension,
                             java.lang.String encoderClassName)

Registers an encoding. The ImageEncoder is instantiated using the specified class name when it is first requested.

Parameters:

type - The mime type of the encoding

extension - The file extension for the encoding

encoderClassName - The name of a class which implements the ImageEncoder interface

unregisterEncoding
