Method Detail

close

public void close()
           throws IOException

Closes this I/O connection, releasing any associated resources. Once closed a connection is no longer valid.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Throws:

IOException - If an I/O error occurs.

getPath

public java.lang.String getPath()

getPos

public int getPos()
           throws IOException

Description copied from class: RandomAccessStream

Returns the current offset in this stream.

Overrides:

getPos in class RandomAccessStream

Returns:

the offset from the beginning of the stream, in bytes, at which the next read or write occurs.

Throws:

IOException - if an I/O error has occurred.

setPos

public void setPos(int offset,
                   int origin)
            throws IOException

Description copied from class: RandomAccessStream

Sets the file pointer for read and write operations to a new position defined by adding offset to a reference position specified by origin.

Specified by:

setPos in class RandomAccessStream

Parameters:

offset - number of bytes to offset from origin.

origin - position from where offset is added. It is specified by one of the SEEK_* constants.

Throws:

IOException - if the new position is negative or if an I/O error occurs.

                     int len)
              throws IOException

Description copied from class: Stream

Reads bytes from the stream. Returns the number of bytes actually read or -1 if the end of the stream was reached. (if applicable to the stream)

Specified by:

setPos

public void setPos(int pos)
            throws IOException

Description copied from class: RandomAccessStream
