SiteUUID

public SiteUUID(UUID uuid,
                java.lang.String name,
                java.lang.String site)

Method Detail

getName

public java.lang.String getName()

getSite

public java.lang.String getSite()

Description copied from interface: SiteAddress

Returns the ID of the site (all sites need to have a unique site ID)

Specified by:

getSite in interface SiteAddress

create

public java.util.function.Supplier<? extends UUID> create()

Description copied from interface: Constructable

Creates an instance of the class implementing this interface

Specified by:

create in interface Constructable<UUID>

Overrides:

create in class ExtendedUUID

copy

public UUID copy()

Overrides:

copy in class UUID

toString

public java.lang.String toString()

Overrides:

toString in class ExtendedUUID

hashCode

public int hashCode()

Description copied from class: UUID

Returns a hash code for this UUID.

Overrides:

hashCode in class UUID

Returns:

A hash code value for this UUID

equals

public boolean equals(java.lang.Object obj)

Description copied from class: UUID

Compares this object to the specified object. The result is true if and only if the argument is not null, is a UUID object, and contains the same most- and least significant bits.

Overrides:

equals in class UUID

Parameters:

obj - The object to be compared

Returns:

true if the objects are the same; false otherwise

compareTo

public int compareTo(Address other)

Description copied from class: UUID

Compares this UUID with the specified UUID.

The first of two UUIDs is greater than the second if the most significant field in which the UUIDs differ is greater for the first UUID.

Specified by:

compareTo in interface java.lang.Comparable<Address>

Overrides:

compareTo in class UUID

Parameters:

other - UUID to which this UUID is to be compared

Returns:

-1, 0 or 1 as this UUID is less than, equal to, or greater than val

isSiteAddress

public boolean isSiteAddress()

Description copied from interface: Address

Whether or not this address is a SiteAddress. Kludgey workaround to avoid the use of instanceof SiteAddress.
Will be removed once the type pollution issue (https://bugs.openjdk.org/browse/JDK-8180450) is fixed.

Specified by:

isSiteAddress in interface Address

Returns:

True if this address is a site address, otherwise false

print

public java.lang.String print(boolean detailed)

serializedSize

public int serializedSize()

Description copied from class: ExtendedUUID

The number of bytes required to serialize this instance

Specified by:

serializedSize in interface SizeStreamable

Overrides:

serializedSize in class ExtendedUUID

writeTo

public void writeTo(java.io.DataOutput out)
             throws java.io.IOException

Description copied from interface: Streamable

Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

Specified by:

writeTo in interface Streamable

Overrides:

writeTo in class ExtendedUUID

Throws:

java.io.IOException

readFrom

public void readFrom(java.io.DataInput in)
              throws java.io.IOException

Description copied from interface: Streamable

Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

Specified by:

readFrom in interface Streamable

Overrides:

readFrom in class ExtendedUUID

Throws:

java.io.IOException

printOthers

protected java.lang.String printOthers()
