Constructor Details

OpenTracByteArray

public OpenTracByteArray()

Create an untyped empty OpenTracByteArray element.

OpenTracByteArray

public OpenTracByteArray(int type,
 byte[] body,
 int offset,
 int length)

Create an OpenTRAC element with an arbitrary-length byte array 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 Details

valueString

public 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

getByteArray

public byte[] getByteArray()

Get the value of this OpenTracByteArray.

Returns:

the encapsulated array of arbitrary bytes

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(Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

See Also:

• hashCode()

hashCode

public int hashCode()

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

See Also:

• Object.equals(Object)

toString

public String toString()

Returns a string representation of the object.

Overrides:

toString in class OpenTracElement

Returns:

a string representation of the object.

equalsElement

public boolean equalsElement(OpenTracElement other)

Test if this OpenTracElement has the same type and value as another OpenTracElement.

Specified by:

equalsElement in class OpenTracElement

Parameters:

other - OpenTracElement to compare against this element

Returns:

boolean true if elements are of the same type, class, and value
