Method Detail

isTypicalValidEntityBareJid

public static boolean isTypicalValidEntityBareJid(CharSequence jid)

Check if the given CharSequence represents a typical and valid entity bare JID. This method does perform the same check as isValidEntityBareJid(CharSequence) and additionally verifies that the domainpart of the JID contains at least one dot ('.') character.

For more information about the different verification methods see validateEntityBareJid(CharSequence).

Parameters:

jid - the CharSequence to check.

Returns:

true if @{code jid} represents a valid entity bare JID, false otherwise

isValidEntityBareJid(CharSequence), EntityBareJid

validateTypicalEntityBareJid

public static EntityBareJid validateTypicalEntityBareJid(CharSequence jidcs)
                                                  throws JidUtil.NotAEntityBareJidStringException,
                                                         XmppStringprepException

Check if the given CharSequence is a typical and valid entity bare JID. This method does perform the same check as isValidEntityBareJid(CharSequence) and additionally verifies that the domainpart of the JID contains at least one dot ('.') character.

The …TypicalValidEntityBareJid(CharSequence) methods are useful if you expect your users to always enter a FQDN as domainpart. Whereas isValidEntityBareJid(CharSequence) and validateEntityBareJid accept also inputs like "foo@example", the "is typical JID" methods require the domainpart to contain a dot, e.g. "foo@example.org".

Parameters:

jidcs - the JID CharSequence

Returns:

a BareJid instance representing the given JID CharSequence

Throws:

JidUtil.NotAEntityBareJidStringException - if the given CharSequence is not a bare JID.

XmppStringprepException - if an error happens.

isValidEntityBareJid

public static boolean isValidEntityBareJid(CharSequence jid)

Check if the given CharSequence represents a valid entity bare JID. That is, it must consists exactly of a local- and a domainpart (<localpart@domainpart>).

This method is meant to validate user input and give fast feedback (e.g. with a red or green light) about if the user entered CharSequence represents a bare JID.

Parameters:

jid - the CharSequence to check.

Returns:

true if @{code jid} represents a valid entity bare JID, false otherwise

validateEntityBareJid

public static EntityBareJid validateEntityBareJid(CharSequence jidcs)
                                           throws JidUtil.NotAEntityBareJidStringException,
                                                  XmppStringprepException

Check if the given CharSequence is a valid entity bare JID. That is, it must consists exactly of a local- and a domainpart (<localpart@domainpart>).

This is a convenience method meant to validate user entered bare JIDs. If the given jid is not a valid bare JID, then this method will throw either JidUtil.NotAEntityBareJidStringException or XmppStringprepException. The NotABareJidStringException will contain a meaningful message explaining why the given CharSequence is not a valid bare JID (e.g. "does not contain a '@' character").

Parameters:

jidcs - the JID CharSequence

Returns:

a BareJid instance representing the given JID CharSequence

Throws:

JidUtil.NotAEntityBareJidStringException - if the given CharSequence is not a bare JID.

XmppStringprepException - if an error happens.
