Class ByteDataVariable

java.lang.Object

org.vishia.byteData.ByteDataVariable

public class ByteDataVariable
extends java.lang.Object

This class contains some static sub classes for Variable with primitive types inside a ByteDataAccessBase-derived access class. It is a new better concept to access single data in generated derived classes of ByteDataAccessBase. Use the following pattern:

 class MyDataAccessClass extends ByteDataAccessBase {
   
   ByteDataVariable.Int16 firstValue = new ByteByteDataVariable.Int16(this, 0);
   
   ByteDataVariable.Uint16 value2 = new ByteByteDataVariable.Int16(this, 2);
   
 }
 

The access class may/should be generated from a header file. The positions are calculated from the header file or are countered accurately. The delegation to operations ByteDataAccessBase.getInt16(int) etc. are no more necessary to access. The access can be done instead via:

   int val = myAccess.value2.get();
 

The important advantage is: The values are seen in debugging via toString-implementations. With them a better view to binary data is given.
