Class BufferFormat

java.lang.Object
  org.otfeed.support.BufferFormat

All Implemented Interfaces:

IFormat<java.nio.ByteBuffer>

public class BufferFormat
extends java.lang.Object
implements IFormat<java.nio.ByteBuffer>

Converts ByteBuffer type to/from a string.

Formats buffer into multi-line string, each line showing up to 16 bytes of the data in a standard "hexdump" format. For example,

 00000001 40360000 00000000 21000001     %....@6......!...
 148a6fe0 69                             %..o.i
 

When parsing, ignores empty lines, and treat separator symbol as start of comment. Therefore, following is a valid input to the parse method:

 %
 % buffer snippet
 %
 00000001 40360000 00000000 21000001     %....@6......!...
 148a6fe0 69                             %..o.i
