public abstract class DIB
extends java.lang.Object

Description Information Block (DIB).

A DIB is used to return device specific information.
This DIB is a common base for more detailed description formats contained in DIBs. For usage of the different description information available, refer to the DIB subtypes.

The currently known valid descriptor type codes (KNXnet/IP core specification v1.2) are defined as available DIB constants.

Field Summary

static short	DEVICE_INFO Description type code for device information e.g.
static short	MFR_DATA Description type code for further data defined by device manufacturer.
static short	SUPP_SVC_FAMILIES Description type code for service families supported by the device.

Constructor Summary

protected

DIB(byte[] data, int offset) Creates a new DIB out of a byte array.

Method Summary

short	getDescTypeCode() Returns the description type code of this DIB.
short	getStructLength() Returns the structure length of this DIB in bytes.
byte[]	toByteArray() Returns the byte representation of the whole DIB structure.

Constructor Detail

DIB

protected DIB(byte[] data,
              int offset)
       throws KNXFormatException

Creates a new DIB out of a byte array.

Parameters:

data - byte array containing DIB structure

offset - start offset of DIB in data

Throws:

KNXFormatException - if no DIB found or invalid structure

Method Detail

getDescTypeCode

public final short getDescTypeCode()

Returns the description type code of this DIB.

The type code specifies which kind of description information is contained in the DIB.

Returns:

description type code as unsigned byte

getStructLength

public final short getStructLength()

Returns the structure length of this DIB in bytes.

Returns:

structure length as unsigned byte

toByteArray

public byte[] toByteArray()

Returns the byte representation of the whole DIB structure.

Returns:

byte array containing structure
