MemoryCacheImageOutputStream (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

javax.imageio.stream
class MemoryCacheImageOutputStream

java.lang.Object
  javax.imageio.stream.ImageInputStreamImpl
      javax.imageio.stream.ImageOutputStreamImpl
          javax.imageio.stream.MemoryCacheImageOutputStream

All Implemented Interfaces:: ImageInputStream, ImageOutputStream

Most common way to construct:

ByteArrayOutputStream baos = …;

MemoryCacheImageOutputStream mos = new MemoryCacheImageOutputStream(baos);

Based on 14 examples

public class MemoryCacheImageOutputStream
extends ImageOutputStreamImpl

An implementation of ImageOutputStream that writes its output to a regular OutputStream. A memory buffer is used to cache at least the data between the discard position and the current write position. The only constructor takes an OutputStream, so this class may not be used for read/modify/write operations. Reading can occur only on parts of the stream that have already been written to the cache and not yet flushed.

Field Summary

Fields inherited from class javax.imageio.stream.ImageInputStreamImpl
`bitOffset, byteOrder, flushedPos, streamPos`

Constructor Summary
`MemoryCacheImageOutputStream(OutputStream stream)` Constructs a `MemoryCacheImageOutputStream` that will write to a given `OutputStream`.

Method Summary
`void`	`close()` Closes this `MemoryCacheImageOutputStream`.
`void`	`flushBefore(long pos)`
`boolean`	`isCached()` Returns `true` since this `ImageOutputStream` caches data in order to allow seeking backwards.
`boolean`	`isCachedFile()` Returns `false` since this `ImageOutputStream` does not maintain a file cache.
`boolean`	`isCachedMemory()` Returns `true` since this `ImageOutputStream` maintains a main memory cache.
`long`	`length()` Returns `-1L` to indicate that the stream has unknown length.
`int`	`read()` Reads a single byte from the stream and returns it as an `int` between 0 and 255.
`int`	`read(byte[] b, int off, int len)` Reads a single byte from the stream and returns it as an `int` between 0 and 255.
`void`	`write(byte[] b, int off, int len)`
`void`	`write(int b)`
