| StreamImageReader | | abstract public class StreamImageReader extends GeographicImageReader (Code) | | Base class for simple image decoders. This class provides a
StreamImageReader.getInputStream method,
which returns the
as an
InputStream for convenience.
Different kinds of input like
or
are automatically
handled.

| Method Summary | |
| protected void | close()
Closes the input stream created by
StreamImageReader.getInputStream() . | | public void | dispose()
Allows any resources held by this reader to be released. | | protected void | finalize()
Closes the streams. | | protected InputStream | getInputStream()
Returns the
as an
object.
If the input is already an input stream, it is returned unchanged. | | protected long | getStreamLength()
Returns the stream length in bytes, or
-1 if unknown. | | public void | reset()
Restores the
StreamImageReader to its initial state. | | public void | setInput(Object input, boolean seekForwardOnly, boolean ignoreMetadata)
Sets the input source to use. |
| StreamImageReader | | protected StreamImageReader(ImageReaderSpi provider)(Code) | | Constructs a new image reader.
Parameters:
provider - The ImageReaderSpi that is invoking this constructor,or null if none. |
| dispose | | public void dispose()(Code) | | Allows any resources held by this reader to be released. If an input stream were created
by a previous call to
StreamImageReader.getInputStream , it will be
before to dispose this reader.
|
| finalize | | protected void finalize() throws Throwable(Code) | | Closes the streams. This method is automatically invoked by the garbage collector.
|
| reset | | public void reset()(Code) | | Restores the
StreamImageReader to its initial state. If an input stream were
created by a previous call to
StreamImageReader.getInputStream , it will be
before to reset this reader.
|
| setInput | | public void setInput(Object input, boolean seekForwardOnly, boolean ignoreMetadata)(Code) | | Sets the input source to use. Input may be one of the following object:
File ,
URL ,
Reader (for ASCII data),
InputStream or
ImageInputStream . If
input is
null , then any currently
set input source will be removed.
Parameters:
input - The input object to use for future decoding.
Parameters:
seekForwardOnly - If true , images and metadata may only be readin ascending order from this input source.
Parameters:
ignoreMetadata - If true , metadata may be ignored during reads.
