Constructor Detail

OPTICS.COEntry

public OPTICS.COEntry(Integer objectID,
                      Integer predecessorID)

Creates a new entry with the specified parameters.

Parameters:

objectID - the id of the entry

predecessorID - the id of the entry's predecessor

Method Detail

compareTo

public int compareTo(Identifiable o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Parameters:

o - the Object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

toString

public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

a string representation of the object.

equals

public boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The result is true if and only if the argument is not null and is an COEntry object and objectID.equals(((COEntry) o).objectID) returns true.

Overrides:

equals in class Object

Parameters:

o - the object to compare with

Returns:

true if the specified object is equal to this one, false otherwise.

hashCode

public int hashCode()

Returns a hash code value for the object which is the hash code of the objectID of this object.

Overrides:

hashCode in class Object

Returns:

the hash code of the objectID of this object

getID

public Integer getID()

Returns the unique id of this object.

Specified by:

getID in interface Identifiable

Returns:

the unique id of this object
