Class MsgItems_h.MsgItem

java.lang.Object

ByteDataAccessBase

org.vishia.msgDispatch.MsgItems_h.MsgItem

Enclosing class:

MsgItems_h

public static class MsgItems_h.MsgItem
extends ByteDataAccessBase

Read one message item form a byte[] data. A message item consist of 28 Byte, which is:

 0                4        6       8             12         16         20         24         28
 +----------------+--------+-------+-------------+----------+----------+----------+----------+
 | timeStamp      | millis |modeVal|   ident     | value1   | value2   | value3   | value4   |
 +----------------+--------+-------+-------------+----------+----------+----------+----------+
 

• The timeStamp is the seconds after 1970 UTC.
• The millis is the milliseconds-value in the second.
• The modeVal contains 2 bits for each value for up to 8 values whereby 4 values are used with this type of datagram. It means only the 8 lo-bits were used.
  • 0 integer value 4 byte
  • 1 reserve
  • 2 reserve
  • 3 float value
• The ident is the message ident which determines the message text (associated in the mesage presentation system) and the possibility for dispatching with the org.vishia.msgDispatch.MsgDispatcherCore.
• Up to 4 values given with the message or 8 values with 16 bit. Not used values are left empty.
