  - RRset
```
public RRset()
```
    Creates an empty RRset
  - RRset
```
public RRset(Record record)
```
    Creates an RRset and sets its contents to the specified record
  - RRset
```
public RRset(Record... records)
```
    Creates an RRset and sets its contents to the specified record(s)
    
    Parameters:
    
    records - The records to add to the set. See addRR(Record) for restrictions.
  - RRset
```
public RRset(RRset rrset)
```
    Creates an RRset with the contents of an existing RRset
- Method Detail
  - addRR
```
public void addRR(RRSIGRecord r)
```
    Adds a signature to this RRset. If the TTL of the added signature is not the same as existing records in the RRset, all records are set to the lowest TTL of either the added record or the existing records.
    
    Throws:
    
    IllegalArgumentException - if the RRset already contains records and the signature to add does not match.
  - addRR
```
public void addRR(Record r)
```
    Adds a Record to this RRset. If the TTL of the added record is not the same as existing records in the RRset, all records are set to the lowest TTL of either the added record or the existing records.
    
    Throws:
    
    IllegalArgumentException - if the RRset already contains records and the record to add does not match.
  - deleteRR
```
public void deleteRR(RRSIGRecord r)
```
    Deletes a signature from this RRset
  - deleteRR
```
public void deleteRR(Record r)
```
    Deletes a record from this RRset
  - clear
```
public void clear()
```
    Deletes all records (including signatures) from this RRset
  - rrs
```
public List<Record> rrs(boolean cycle)
```
    Returns a list of all data records.
    
    Parameters:
    
    cycle - If true, cycle through the records so that each list will start with a different record.
  - rrs
```
public List<Record> rrs()
```
    Returns a list of all data records. This cycles through the records, so that each returned list will start with a different record.
  - sigs
```
public List<RRSIGRecord> sigs()
```
    Returns a list of all signature records.
  - size
```
public int size()
```
    Returns the number of (data) records
  - getName
```
public Name getName()
```
    Returns the name of the records
    
    See Also:
    
    Name
  - getType
```
public int getType()
```
    Returns the type of the records

  - getDClass
```
public int getDClass()
```
    Returns the class of the records

  - getTTL
```
public long getTTL()
```
    Returns the ttl of the records
  - first
```
public Record first()
```
    Returns the first record in this RRset, either an RR or a signature.
    
    Throws:
    
    IllegalStateException - if the RRset is empty
  - toString
```
public String toString()
```
    Converts the RRset to a String
    
    Overrides:
    
    toString in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
