Member Function Documentation

float de.stz.bt.fnd.datapoints.FND_Value.getFloatValue (   ) 
 

Returns float value of stored IEEE-value.

Returns:
Float representation of stored IEEE-value.

00090                                 {
00091     return Float.intBitsToFloat(value);
00092   }

int de.stz.bt.fnd.datapoints.FND_Value.getIntValue (   ) 
 

Returns integer value of stored IEEE-value.

Returns:
Integer representation of stored IEEE-value.

00071                             {
00072     int returnValue = (int)Float.intBitsToFloat(value);
00073     return returnValue;
00074   }

byte [] de.stz.bt.fnd.datapoints.FND_Value.getShortRealValue (   ) 
 

Returns the stored value as a four byte array. No format conversion is done.

Returns:
A four byte array containg the stored value.

00117                                     {
00118     byte[] returnValue = new byte[4];
00119     returnValue[0] = (byte) (value >>> 24);
00120     returnValue[1] = (byte)((value >>> 16) & 0x00FF);
00121     returnValue[2] = (byte)((value >>>  8) & 0x0000FF);
00122     returnValue[3] = (byte)(value & 0x000000FF);
00123     return returnValue;
00124   }

void de.stz.bt.fnd.datapoints.FND_Value.setFloatValue (  float  floatValue  ) 
 

Stores float-value as IEEE-value.

Parameters:
floatValue Float-value to be stored.

00081                                                {
00082     this.value = Float.floatToIntBits(floatValue);
00083   }

void de.stz.bt.fnd.datapoints.FND_Value.setIntValue (  int  intValue  ) 
 

Stores Integer-Value in IEEE-format

Parameters:
intValue 

00062                                          {
00063     this.value = Float.floatToIntBits((float)intValue);
00064   }

void de.stz.bt.fnd.datapoints.FND_Value.setShortRealValue (  byte[]  byteValue  )  throws IndexOutOfBoundsException
 

Stores a byte array of four elements. No format conversion is done.

Parameters:
byteValue The byte array to be stored.
Exceptions:
IndexOutOfBoundsException If the array length is unequal to four.

00102                                                                                     {
00103     if (byteValue.length != 4) {
00104       throw (new IndexOutOfBoundsException("FND_Value.setShortRealValue: valueArray-length unequal to 4, current length="+byteValue.length+" required length = 4 Bytes"));
00105     }
00106     this.value  = (byteValue[0] << 24);
