Update

public Update(Name zone,
              int dclass)

Creates an update message.

Parameters:

zone - The name of the zone being updated.

dclass - The class of the zone being updated.

Update

public Update(Name zone)

Creates an update message. The class is assumed to be IN.

Parameters:

zone - The name of the zone being updated.

Method Detail

present

public void present(Name name)

Inserts a prerequisite that the specified name exists; that is, there exist records with the given name in the zone.

present

public void present(Name name,
                    int type)

Inserts a prerequisite that the specified rrset exists; that is, there exist records with the given name and type in the zone.

present

public void present(Name name,
                    int type,
                    String record)
             throws IOException

Parses a record from the string, and inserts a prerequisite that the record exists. Due to the way value-dependent prequisites work, the condition that must be met is that the set of all records with the same and type in the update message must be identical to the set of all records with that name and type on the server.

Throws:

IOException - The record could not be parsed.

             throws IOException

Parses a record from the tokenizer, and inserts a prerequisite that the record exists. Due to the way value-dependent prequisites work, the condition that must be met is that the set of all records with the same and type in the update message must be identical to the set of all records with that name and type on the server.
