Specified by:

openOutput in class LExport

Parameters:

path - Path to open a channel to.

Throws:

java.io.FileNotFoundException

write

public void write(byte[] array)
           throws java.io.IOException

Description copied from class: LExport

Writes a byte array to the file.

Specified by:

write in class LExport

Throws:

java.io.IOException

write

public void write(byte b)
           throws java.io.IOException

close in class LExport

Throws:

java.io.IOException

markLength

public void markLength(int size)
                throws java.io.IOException

A stack-based system where you can declare an amount of bytes to represent the length of some upcoming data. Later on you can closeLength() which will update the bytes to contain the size of the data in-between.

Parameters:

size - Number of bytes to write/reserve for the length information.

Throws:

java.io.IOException

closeLength

public void closeLength()
                 throws java.io.IOException

Used in conjunction with markLength(int). Updates the most recent markLength(int) reserved bytes to contain the length of data in between them and the current position.

Throws:

java.io.IOException

setPosMarker

public void setPosMarker(int size)
                  throws java.io.IOException

A queue-based system where you can declare an amount of bytes to represent the position of some upcoming data. Late on you can fillPosMarker() which will update the bytes to contain the position the channel is currently at.

Parameters:

size - Number of bytes to write/reserve for the position information.

Throws:

java.io.IOException

fillPosMarker

public void fillPosMarker()
                   throws java.io.IOException

Used in conjunction with setPosMarker(int). Updates the next-in-queue setPosMarker(int) reserved bytes to contain the current position of the channel.

Throws:

java.io.IOException

pos

public void pos(long set)
         throws java.io.IOException

Parameters:

set -

Throws:

java.io.IOException

pos

         throws java.io.IOException

Returns:

Throws:

java.io.IOException
