TLDInfo

public TLDInfo(java.lang.String name)

Create TLD info holder.

Parameters:

name - The TLD domain name.

Method Detail

getName

public java.lang.String getName()

The name of this TLD (e.g. dk, com or museum). IP addresses are registered under a special "IP address" name.

Returns:

TLD name without .

getCount

public int getCount()

Number of subdomains we have registered under this TLD. All IP addresses are lumped together as one TLD.

Returns:

Number of 2nd-level domains we have registered under this TLD.

addSubdomain

void addSubdomain(java.lang.String name)

Add a 2nd-level domain to the information for this domain. This tests that the given domain does in fact belong to this TLD, but not whether it has been added before.

Parameters:

name - A name of a domain

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

the hashcode for this object which is equal to the hashCode for the name of the tld.

See Also:

Object.hashCode()

compareTo

public int compareTo(TLDInfo 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.

Specified by:

compareTo in interface java.lang.Comparable<TLDInfo>

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.

See Also:

Comparable.compareTo(Object o)

getTLD

static java.lang.String getTLD(java.lang.String domain)

Get the TLD for a given domain.

Parameters:

domain - A domain, as specified by the global domain regexp.

Returns:

The TLD of the domain, or a special placeholder for IP addresses.

getMultiLevelTLD

static java.lang.String getMultiLevelTLD(java.lang.String domain,
                                         int maxLevel)

Get the TLD for a given domain including multilevel TLD. for example .gouv.fr is level 2 TLD

Parameters:

domain - A domain, as specified by the global domain regexp.

maxLevel - maximum level for TLD (can't be 0).

Returns:

The TLD of the domain, or a special placeholder for IP addresses.

getTLDLevel

static int getTLDLevel(java.lang.String domain)

Return TLD level of the domain.

Parameters:

domain - A domain

Returns:

TLD level of the domain 1 for IP addresses

isIP

public boolean isIP()

True if this TLDinfo accumulates IP address information.

Returns:

True if the domains counted in the TLDinfo are IP domains.
