skipBytes

public int skipBytes(int count)
              throws IllegalArgumentIOException,
                     IOException

Description copied from class: Stream

Skips over and discards n bytes of data from this stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. This may result from any of a number of conditions; reaching end of file before n bytes have been skipped is only one possibility. The actual number of bytes skipped is returned. If n is negative, no bytes are skipped, but this may vary among some implementations of skipBytes in classes that inherit them (like File and PDBFile).

The skip method of this class uses a static byte array, repeatedly reading into it until n bytes have been read or the end of the stream has been reached. Subclasses are encouraged to provide a more efficient implementation of this method. For instance, the implementation may depend on the ability to seek.

Overrides:

skipBytes in class Stream

Parameters:

count - the number of bytes to be skipped.

Returns:

the actual number of bytes skipped.

Throws:

IOException - if the stream does not support skip, or if some other I/O error occurs.

IllegalArgumentIOException

getRecordSize

public int getRecordSize()
                  throws IOException

Throws:

IOException

getRecordPos

public final int getRecordPos()

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 Once closed a connection is no longer valid.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.

readBytes

public final int readBytes(byte[] buf,
                           int start,
                           int count)
                    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:

readBytes in class Stream

Parameters:

buf - the byte array to read data into

start - the start position in the array

count - the number of bytes to read

Throws:

IOException

writeBytes

public final int writeBytes(byte[] buf,
                            int start,
                            int count)
                     throws IOException

Description copied from class: Stream

Writes bytes to the stream. Returns the number of bytes actually written or throws an IOException if an error prevented the write operation from occurring.

Specified by:

writeBytes in class Stream

Parameters:

buf - the byte array to write data from

start - the start position in the byte array

count - the number of bytes to write

Returns:

the number of bytes actually written
