Method Detail

toString

public String toString()

Overrides:

toString in class Object

isTrivial

public boolean isTrivial()

Description copied from interface: Identifier

Is the underlying URI trivial, i.e. null or an empty string?

Specified by:

isTrivial in interface Identifier

Returns:

getUri

public URI getUri()

Description copied from interface: Identifier

Return this identifier as a URI.

Specified by:

getUri in interface Identifier

Returns:

newID

public static Identifier newID(String id)

Create a new identifier from a given string.

Parameters:

id -

Returns:

newID

public static Identifier newID(URI uri)

Create a new identifier from a given URI.

Parameters:

uri -

Returns:

randomID

public static Identifier randomID()

Create a random id. Never use random IDs in for things that grant security access, since these are random which does not imply they are unguessable. Random IDs are useful for internal identifiers (such as for objects) or for testing.

Returns:

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable

main

public static void main(String[] args)
