Constructor Detail

OpenTracFloat

public OpenTracFloat()
Create an uninitialized OpenTracFloat element.


OpenTracFloat

public OpenTracFloat(int type,
                     byte[] body,
                     int offset,
                     int length)
Create an OpenTRAC element with a single-precision floating point value from the next series of bytes in an encoded OpenTRAC message.

Parameters:
type - OpenTRAC element type code
body - byte array containing the encoded OpenTRAC elements
offset - starting index in the array where this element begins
length - remaining number of bytes in the OpenTRAC encoded message
Method Detail

valueString

public java.lang.String valueString()
Get the string representation of the value of this element.

Specified by:
valueString in class OpenTracElement
Returns:
value string

computeBody

public int computeBody(byte[] buf,
                       int offset)
Append this element to a message buffer

Specified by:
computeBody in class OpenTracElement
Parameters:
buf - byte array to add the element to
offset - starting index to store the element
Returns:
index after the end of the stored element

length

public int length()
Return the number of bytes needed to encode this element.

Specified by:
length in class OpenTracElement
Returns:
byte count needed to hold this element

equals

public boolean equals(OpenTracElement other)
Test if this OpenTracElement has the same type and value as another OpenTracElement.

Specified by:
equals in class OpenTracElement
Parameters:
other - OpenTracElement to compare against this element
Returns:
boolean true if elements are of the same type, class, and value
