ImageInputStreamImpl JDK 1.6)

protectedfinal void checkClosed () throws IOException

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 [Specified in ImageInputStream]

protected void finalize () throws Throwable

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.
Throws:
- Throwable - if an error occurs during superclass finalization.

public void flush () throws IOException [Specified in ImageInputStream]

public void flushBefore (long pos) throws IOException [Specified in ImageInputStream]

public int getBitOffset () throws IOException [Specified in ImageInputStream]

public ByteOrder getByteOrder () [Specified in ImageInputStream]

public long getFlushedPosition () [Specified in ImageInputStream]

public long getStreamPosition () throws IOException [Specified in ImageInputStream]

public boolean isCached () [Specified in ImageInputStream]

Default implementation returns false.

public boolean isCachedFile () [Specified in ImageInputStream]

Default implementation returns false.

public boolean isCachedMemory () [Specified in ImageInputStream]

Default implementation returns false.

public long length () [Specified in ImageInputStream]

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 () [Specified in ImageInputStream]

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

publicabstract int read () throws IOException [Specified in ImageInputStream]

Reads a single byte from the stream and returns it as an int between 0 and 255.

Reads a single byte from the stream and returns it as an int between 0 and 255. If EOF is reached, -1 is returned.

Subclasses must provide an implementation for this method. The subclass implementation should update the stream position before exiting.

The bit offset within the stream must be reset to zero before the read occurs.
Returns: the value of the next byte in the stream, or -1 if EOF is reached.
Throws:
- IOException - if the stream has been closed.

public int read (byte[] b) throws IOException [Specified in ImageInputStream]

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.

publicabstract int read (byte[] b, int off, int len) throws IOException [Specified in ImageInputStream]

Reads up to len bytes from the stream, and stores them into b starting at index off.

Reads up to len bytes from the stream, and stores them into b starting at index off. If no bytes can be read because the end of the stream has been reached, -1 is returned.

The bit offset within the stream must be reset to zero before the read occurs.

Subclasses must provide an implementation for this method. The subclass implementation should update the stream position before exiting.
Returns: the number of bytes actually read, or -1 to indicate EOF.
Parameters:
- b - an array of bytes to be written to.
- off - the starting position within b to write to.
- len - the maximum number of bytes to read.
Throws:
- IndexOutOfBoundsException - if off is negative, len is negative, or off + len is greater than b.length.
- NullPointerException - if b is null.
- IOException - if an I/O error occurs.

public int skipBytes (int n) throws IOException [Specified in ImageInputStream]

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.

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.
