SeekableByteArrayOutputStream()
Creates a new byte array output stream. |
|
SeekableByteArrayOutputStream(int size)
Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes. |
Method Summary | |
---|---|
long |
getStreamPosition()
Returns the current byte position of the stream. |
void |
reset()
Resets the count field of this byte array output
stream to zero, so that all currently accumulated output in the
output stream is discarded. |
void |
seek(long pos)
Sets the current stream position to the desired location. |
void |
toOutputStream(java.io.OutputStream out)
Writes the contents of the byte array into the specified output stream. |
void |
write(byte[] b,
int off,
int len)
Writes len bytes from the specified byte array
starting at offset off to this byte array output stream. |
void |
write(int b)
Writes the specified byte to this byte array output stream. |

b
- the byte to be written.public void write(byte[] b, int off, int len)
len
bytes from the specified byte array
starting at offset off
to this byte array output stream.

in class java.io.ByteArrayOutputStream
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.public void reset()
count
field of this byte array output
stream to zero, so that all currently accumulated output in the
output stream is discarded. The output stream can be used again,
reusing the already allocated buffer space.

public void seek(long pos) throws java.io.IOException
An IndexOutOfBoundsException
will be thrown if
pos
is smaller than the flushed position (as
returned by getflushedPosition
).
It is legal to seek past the end of the file; an
EOFException
will be thrown only if a read is
performed.
pos
- a long
containing the desired file
pointer position.
java.lang.IndexOutOfBoundsException
- if pos
is smaller
than the flushed position.
java.io.IOException
- if any other I/O error occurs.public long getStreamPosition() throws java.io.IOException
