All Implemented Interfaces:

MemoryTools.Internable

Enclosing class:

GeoUtils

public static final class GeoUtils.CCTLD
extends java.lang.Object
implements MemoryTools.Internable

An immutable DNS ccTLD (two-letter) country code. Lower-case, two-ASCII-letter code.

This is not the ISO3316-1 code; eg the United Kingdom is "uk" not "gb" though "gb" may be acceptable as an alias.

code

public final java.lang.String code

The two-letter lower-case-ASCII ccTLD; never null.

GeoUtils.CCTLD

public GeoUtils.CCTLD(java.lang.String code)

Construct instance. Supplied code must not be null and must consist of exactly two lower-case 7-bit-ASCII letters.

The code is only checked for syntax, not that such a country code actually exists.

isSyntaticallyValidCcTLD

public static boolean isSyntaticallyValidCcTLD(java.lang.String code)

True if argument is a (non-null) syntactically-valid ccTLD code. This only looks for syntactic validity.

Returns:

true iff two-letter lower-case-ASCII argument; false for null or otherwise-invalid arguments

hashCode

public int hashCode()

A fast hash reflecting approx ~5 bits of information per char.

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Two ccTLDs are the same if their underlying codes are the same.

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

This returns the code as its String representation.

Overrides:

toString in class java.lang.Object
