Constants

UNSPECIFIED_CHANNEL

int UNSPECIFIED_CHANNEL

Value returned from getChannel() when no channel was specified.

Constant Value: -1 (0xffffffff)

int UNSPECIFIED_PANID

Value returned from getPanid() when no PANID was specified.

Constant Value: -1 (0xffffffff)

Public methods

equals

boolean equals (Object rhs)

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

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null 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).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`rhs`	`Object`: the reference object with which to compare.

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

getChannel

int getChannel ()

Returns the channel index for this LowpanIdentity.

If not set, will return UNSPECIFIED_CHANNEL.

Returns
`int`

See also:

UNSPECIFIED_CHANNEL

getName

String getName ()

Returns the name of the network.

Note that if the name of this network is not considered normal or ambiguous, the returned string will be escaped into a non-ambigous form. To get the actual byte values for the network name, use getRawName().

Returns
`String`

See also:

getRawName()
isNameValid()

getPanid

int getPanid ()

Returns the PANID for this LowpanIdentity.

If not set, will return UNSPECIFIED_PANID.

Returns
`int`

See also:

UNSPECIFIED_PANID

getRawName

byte[] getRawName ()

Returns the raw bytes for the network name.

These bytes may differ from the UTF8 encoding of the result from getName() if the network name is not considered normal or ambiguous.

Returns
`byte[]`

See also:

getName()
isNameValid()

getXpanid

byte[] getXpanid ()

Returns the XPANID for this LowpanIdentity.

If not set, will return an empty array.

Returns
`byte[]`

hashCode

int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

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 Java™ programming language.)

Returns
`int`	a hash code value for this object.

isNameValid

boolean isNameValid ()

Indicates if the raw network name is a valid and normalized UTF8 encoding.

Returns
`boolean`	`true` if the network name is valid and normalized UTF8. `false` otherwise.

See also:

getName()
getRawName()

toString

String toString ()

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())

Returns
`String`	a string representation of the object.
