Method Detail

isBetween

public boolean isBetween(Id ccw,
                         Id cw)

Description copied from interface: Id

Checks if this Id is between two given ids ccw (inclusive) and cw (exclusive) on the circle

Specified by:

isBetween in interface Id

Parameters:

ccw - the counterclockwise id

cw - the clockwise id

Returns:

true if this is between ccw (inclusive) and cw (exclusive), false otherwise

clockwise

public boolean clockwise(Id nid)

Description copied from interface: Id

Checks to see if the Id nid is clockwise or counterclockwise from this, on the ring. An Id is clockwise if it is within the half circle clockwise from this on the ring. An Id is considered counter-clockwise from itself.

Specified by:

clockwise in interface Id

Parameters:

nid - The id to compare to

Returns:

true if clockwise, false otherwise.

addToId

public Id addToId(Id.Distance offset)

Description copied from interface: Id

Returns an Id corresponding to this Id plus a given distance

Specified by:

addToId in interface Id

Parameters:

offset - the distance to add

Returns:

the new Id

distanceFromId

public Id.Distance distanceFromId(Id nid)

Description copied from interface: Id

Returns the shorter numerical distance on the ring between a pair of Ids.

Specified by:

distanceFromId in interface Id

Parameters:

nid - the other node id.

Returns:

the distance between this and nid.

longDistanceFromId

public Id.Distance longDistanceFromId(Id nid)

Description copied from interface: Id

Returns the longer numerical distance on the ring between a pair of Ids.

Specified by:

longDistanceFromId in interface Id

Parameters:

nid - the other node id.

Returns:

the distance between this and nid.

toByteArray

public byte[] toByteArray()

Description copied from interface: Id

Returns a (mutable) byte array representing this Id

Specified by:

toByteArray in interface Id

Returns:

A byte[] representing this Id

toByteArray

public void toByteArray(byte[] array,
                        int offset)

Description copied from interface: Id

Stores the byte[] value of this Id in the provided byte array

Specified by:

toByteArray in interface Id

getByteArrayLength

public int getByteArrayLength()

Description copied from interface: Id

Returns the length of the byte[] representing this Id

Specified by:

getByteArrayLength in interface Id

Returns:

The length of the byte[] representing this Id

toStringFull

public java.lang.String toStringFull()

Description copied from interface: Id

Returns a string representing the full length of this Id.

Specified by:

toStringFull in interface Id

Returns:

A string with all of this Id

compareTo

public int compareTo(java.lang.Object o)

Specified by:

compareTo in interface java.lang.Comparable
