pack-priv int	countConsumers(ImageConsumerQueue cq)
pack-priv synchronized int	countConsumers()
protected ImageDecoder	decoderForType(InputStream is, String content_type)
public void	doFetch() Implements sun.awt.image.ImageFetchable.doFetch. This method is called by one of the ImageFetcher threads to start the flow of information from the ImageProducer to the ImageConsumer.
pack-priv synchronized void	doneDecoding(ImageDecoder mydecoder)
private void	errorAllConsumers(ImageConsumerQueue cq, boolean needReload)
private void	errorConsumer(ImageConsumerQueue cq, boolean needReload)
pack-priv synchronized void	flush()
protected abstract ImageDecoder	getDecoder()
protected ImageDecoder	getDecoder(InputStream is)
public synchronized boolean	isConsumer(ImageConsumer ic) Implements java.awt.image.ImageProducer.isConsumer. Determines if a specified `ImageConsumer` object is currently registered with this `ImageProducer` as one of its consumers.

public synchronized void	removeConsumer(ImageConsumer ic) Implements java.awt.image.ImageProducer.removeConsumer. Removes the specified `ImageConsumer` object from the list of consumers currently registered to receive image data.
private synchronized void	removeDecoder(ImageDecoder mydecoder)
public void	requestTopDownLeftRightResend(ImageConsumer ic) Implements java.awt.image.ImageProducer.requestTopDownLeftRightResend. Requests, on behalf of the `ImageConsumer`, that the `ImageProducer` attempt to resend the image data one more time in TOPDOWNLEFTRIGHT order so that higher quality conversion algorithms which depend on receiving pixels in order can be used to produce a better output version of the image.
private void	setDecoder(ImageDecoder mydecoder)
public void	startProduction(ImageConsumer ic) Implements java.awt.image.ImageProducer.startProduction. Registers the specified `ImageConsumer` object as a consumer and starts an immediate reconstruction of the image data which will then be delivered to this consumer and any other consumer which might have already been registered with the producer.

addConsumer back to summary

addConsumer	back to summary
public void addConsumer(ImageConsumer ic) Implements java.awt.image.ImageProducer.addConsumer. Doc from java.awt.image.ImageProducer.addConsumer. Registers an `ImageConsumer` with the `ImageProducer` for access to the image data during a later reconstruction of the `Image`. The `ImageProducer` may, at its discretion, start delivering the image data to the consumer using the `ImageConsumer` interface immediately, or when the next available image reconstruction is triggered by a call to the `startProduction` method.

removeConsumer	back to summary
public synchronized void removeConsumer(ImageConsumer ic) Implements java.awt.image.ImageProducer.removeConsumer. Doc from java.awt.image.ImageProducer.removeConsumer. Removes the specified `ImageConsumer` object from the list of consumers currently registered to receive image data. It is not considered an error to remove a consumer that is not currently registered. The `ImageProducer` should stop sending data to this consumer as soon as is feasible.

requestTopDownLeftRightResend	back to summary
public void requestTopDownLeftRightResend(ImageConsumer ic) Implements java.awt.image.ImageProducer.requestTopDownLeftRightResend. Doc from java.awt.image.ImageProducer.requestTopDownLeftRightResend. Requests, on behalf of the `ImageConsumer`, that the `ImageProducer` attempt to resend the image data one more time in TOPDOWNLEFTRIGHT order so that higher quality conversion algorithms which depend on receiving pixels in order can be used to produce a better output version of the image. The `ImageProducer` is free to ignore this call if it cannot resend the data in that order. If the data can be resent, the `ImageProducer` should respond by executing the following minimum set of `ImageConsumer` method calls: `ic.setHints(TOPDOWNLEFTRIGHT \| < otherhints >); ic.setPixels(...); // As many times as needed ic.imageComplete();`

public void requestTopDownLeftRightResend(ImageConsumer ic)

startProduction	back to summary
public void startProduction(ImageConsumer ic) Implements java.awt.image.ImageProducer.startProduction. Doc from java.awt.image.ImageProducer.startProduction. Registers the specified `ImageConsumer` object as a consumer and starts an immediate reconstruction of the image data which will then be delivered to this consumer and any other consumer which might have already been registered with the producer. This method differs from the addConsumer method in that a reproduction of the image data should be triggered as soon as possible.
