| Method Summary |
|
| abstract public InputStream | asInputStream()
A
InputStream view on the data structure. |
| abstract public OutputStream | asOutputStream()
A
OutputStream view on the data structure. |
| public void | close()
Closes this random access data container and releases any system
resources associated with the stream. |
| public void | flush()
Force changes to be made persistent. |
| public long | getLength()
Returns the length of this data container. |
| public long | getOffset()
Returns the current offset in this data container. |
| public boolean | isReadOnly()
true if this is a read only data container. |
| abstract public void | mark()
Mark the current offset into the data in a stack like manner. |
| public int | read()
Reads a byte of data from this data container. |
| public int | read(byte[] buffer)
Reads up to buffer.length bytes of data from this data
container into an array of bytes. |
| public int | read(byte[] buffer, int start, int numBytes)
Reads up to len bytes of data from this data container
into an array of bytes. |
| abstract public void | reset()
Reset to the last position on the mark-stack. |
| public void | seek(long offset)
Sets the offset, measured from the beginning of the data container at
which the next read or write occurs. |
| public void | seekBy(long delta)
Sets the offset, measured from the current offset at which the next read
or write occurs. |
| public void | setLength(long newLength)
Assign the length. |
| public void | write(int b)
Writes the specified byte . |
| public void | write(byte[] buffer)
Writes b.length bytes from the specified byte array,
starting at the current offset. |
| abstract public void | write(byte[] buffer, int start, int numBytes)
Writes len bytes from the specified byte array starting at
start. |
