Method Detail

toDottedHex

public static String toDottedHex(long address)
Convert a numeric address into a dotted-hex string

Parameters:
address - the address to convert
Returns:
the dotted-hex string

toLong

public static long toLong(String ieeeAddressString)
Convert a string representation of the address to a numeric value. On the host computer, the string is first looked up in the keys of the property file spot.names in the user's home directory. If present, the corresponding value is used in place of the string parameter. Then, the string is first assumed to be dotted hex (that's four four-digit hex numbers separated by full stops). If that conversion fails, the string is parsed as a decimal number. On the host computer, the strng

Parameters:
ieeeAddressString - the string to convert
Returns:
the numeric value of the address

asDottedHex

public String asDottedHex()
Generate a dotted hex string from an IEEE address

Returns:
a dotted hex string

asLong

public long asLong()

toString

public String toString()
Description copied from class: Object
Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:
toString in class Object
Returns:
a string representation of the object.

equals

public boolean equals(Object anObject)
Description copied from class: Object
Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation:

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).

Overrides:
equals in class Object
Parameters:
anObject - the reference object with which to compare.
Returns:
true if this object is the same as the obj argument; false otherwise.

Boolean.hashCode(), Hashtable

hashCode

public int hashCode()
Description copied from class: Object
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.

The general contract of hashCode is:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.

Object.equals(java.lang.Object), Hashtable
