Class InformationObject

java.lang.Object

org.openmuc.j60870.ie.InformationObject

public class InformationObject
extends java.lang.Object

Every Information Object contains:

• The Information Object Address (IOA) that is 1, 2 or 3 bytes long.
• A set of Information Elements or a sequence of information element sets. The type of information elements in the set and their order depend on the ASDU's TypeId and is the same for all information objects within one ASDU. If the sequence bit is set in the ASDU then the ASDU contains a single Information Object containing a sequence of information element sets. If the sequence bit is not set the ASDU contains a sequence of information objects each containing only single information elements sets.

                                throws java.io.IOException

Throws:

java.io.IOException

encode

public int encode(byte[] buffer,
                  int i,
                  int ioaFieldLength)

getInformationObjectAddress

public int getInformationObjectAddress()

getInformationElements

public InformationElement[][] getInformationElements()

Returns the information elements as a two dimensional array. The first dimension of the array is the index of the sequence of information element sets. The second dimension is the index of the information element set. For example an information object containing a single set of three information elements will have the dimension [1][3]. Note that you will have to cast the returned InformationElements to a concrete implementation in order to access the data inside them.

Returns:

the information elements as a two dimensional array.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
