MemoryCacheImageInputStream JDK 1.6)

Methods

protectedfinal void checkClosed () throws IOException [Inherited From ImageInputStreamImpl]

Throws an IOException if the stream has been closed.

Throws an IOException if the stream has been closed.
Subclasses may call this method from any of their methods that
require the stream not to be closed.
Throws:
- IOException - if the stream is closed.

public void close () throws IOException [Overrides ImageInputStreamImpl]

Closes this MemoryCacheImageInputStream, freeing the cache.

Closes this MemoryCacheImageInputStream, freeing
the cache. The source InputStream is not closed.

protected void finalize () throws Throwable [Overrides ImageInputStreamImpl]

Finalizes this object prior to garbage collection.

Finalizes this object prior to garbage collection. The
close method is called to close any open input
source. This method should not be called from application
code.

public void flush () throws IOException [Inherited From ImageInputStreamImpl]

public void flushBefore (long pos) throws IOException [Overrides ImageInputStreamImpl]

public int getBitOffset () throws IOException [Inherited From ImageInputStreamImpl]

public ByteOrder getByteOrder () [Inherited From ImageInputStreamImpl]

public long getFlushedPosition () [Inherited From ImageInputStreamImpl]

public long getStreamPosition () throws IOException [Inherited From ImageInputStreamImpl]

public boolean isCached () [Overrides ImageInputStreamImpl]

Returns true since this ImageInputStream caches data in order to allow seeking backwards.

Returns true since this
ImageInputStream caches data in order to allow
seeking backwards.
Returns: true.

public boolean isCachedFile () [Overrides ImageInputStreamImpl]

Returns false since this ImageInputStream does not maintain a file cache.

Returns false since this
ImageInputStream does not maintain a file cache.
Returns: false.
See Also: MemoryCacheImageInputStream.isCached(), MemoryCacheImageInputStream.isCachedMemory(),

public boolean isCachedMemory () [Overrides ImageInputStreamImpl]

Returns true since this ImageInputStream maintains a main memory cache.

Returns true since this
ImageInputStream maintains a main memory cache.
Returns: true.
See Also: MemoryCacheImageInputStream.isCached(), MemoryCacheImageInputStream.isCachedFile(),

public long length () [Inherited From ImageInputStreamImpl]

Returns -1L to indicate that the stream has unknown length.

Returns -1L to indicate that the stream has unknown
length. Subclasses must override this method to provide actual
length information.
Returns: -1L to indicate unknown length.

public void mark () [Inherited From ImageInputStreamImpl]

Pushes the current stream position onto a stack of marked positions.

public int read () throws IOException [Specified in ImageInputStreamImpl]

public int read (byte[] b) throws IOException [Inherited From ImageInputStreamImpl]

A convenience method that calls read(b, 0, b.length).

The bit offset within the stream is reset to zero before the read occurs.
Returns: the number of bytes actually read, or -1 to indicate EOF.
Throws:
- NullPointerException - if b is null.
- IOException - if an I/O error occurs.

public void setBitOffset (int bitOffset) throws IOException [Inherited From ImageInputStreamImpl]

public void setByteOrder (ByteOrder byteOrder) [Inherited From ImageInputStreamImpl]

public int skipBytes (int n) throws IOException [Inherited From ImageInputStreamImpl]

Advances the current stream position by calling seek(getStreamPosition() + n).

The bit offset is reset to zero.
Returns: an int representing the number of bytes skipped.
Parameters:
- n - the number of bytes to seek forward.
Throws:
- IOException - if getStreamPosition throws an IOException when computing either the starting or ending position.

Advances the current stream position by calling seek(getStreamPosition() + n).

The bit offset is reset to zero.
Returns: a long representing the number of bytes skipped.
Parameters:
- n - the number of bytes to seek forward.
Throws:
- IOException - if getStreamPosition throws an IOException when computing either the starting or ending position.

Fields

Hide/Show inherited fields

protected int bitOffset [Inherited From ImageInputStreamImpl]

The current bit offset within the stream.

pack-private byte byteBuf [Inherited From ImageInputStreamImpl]

Byte buffer used for readFully(type[], int, int).

protected ByteOrder byteOrder [Inherited From ImageInputStreamImpl]

The byte order of the stream as an instance of the enumeration class java.nio.ByteOrder, where ByteOrder.BIG_ENDIAN indicates network byte order and ByteOrder.LITTLE_ENDIAN indicates the reverse order.

The byte order of the stream as an instance of the enumeration
class java.nio.ByteOrder, where
ByteOrder.BIG_ENDIAN indicates network byte order
and ByteOrder.LITTLE_ENDIAN indicates the reverse
order. By default, the value is
ByteOrder.BIG_ENDIAN.

protected long flushedPos [Inherited From ImageInputStreamImpl]

The position prior to which data may be discarded.

The position prior to which data may be discarded. Seeking
to a smaller position is not allowed. flushedPos
will always be >= 0.

protected long streamPos [Inherited From ImageInputStreamImpl]

The current read position within the stream.
