## org.jivesoftware.openfire.resultsetmanager
Class ResultSet<E extends Result>

    java.lang.Object
      java.util.AbstractCollection<E>
          org.jivesoftware.openfire.resultsetmanager.ResultSet<E>

Type Parameters:
  `E` - Each result set should be a collection of instances of the exact same class. This class must implement the `Result` interface.

All Implemented Interfaces:
  Iterable<E>, Collection<E>

Direct Known Subclasses:
  ResultSetImpl

Deprecated. Replaced by `ResultSet`

    @Deprecated
    public abstract class ResultSet<E extends Result>

extends AbstractCollection<E>

A result set representation as described in XEP-0059. A result set is a collection of objects that each have a unique identifier (UID). It's expected that some implementations will have the complete result set loaded into memory, whereas more complex implementations might keep references to partial sets only. This latter would have considerable advantages if the result set is extremely large, or if the operation to get all results in the set is expensive.

  Deprecated.

Method Detail

### getAfter

    public List<E> getAfter(E result,
                            int maxAmount)

  Deprecated.
  Returns a List of results starting with the first result after the provided result (the returned List is exclusive). The lenght of the list is equal to 'maxAmount', unless there are no more elements available (in which case the length of the result will be truncated).

  Parameters:
    `result` - The element that is right before the first element in the result.
    `maxAmount` - The maximum number of elements to return.
  Returns:
    A List of elements the are exactly after the element that is provided as a parameter.
  Throws:
    `NullPointerException` - if the result does not exist in the result set.

### getAfter

    public abstract List<E> getAfter(String uid,
                                     int maxAmount)

  Deprecated.
  Returns a List of results starting with the first result after the result that's identified by the provided UID (the returned List is exclusive). The lenght of the list is equal to 'maxAmount', unless there are no more elements available (in which case the length of the result will be truncated).

  Parameters:
    `uid` - The UID of the element that is right before the first element in the result.
    `maxAmount` - The maximum number of elements to return.
  Returns:
    A List of elements the are exactly after the element that is provided as a parameter.
  Throws:
    `NullPointerException` - if there is no result in the result set that matches the UID.

### getBefore

    public List<E> getBefore(E result,
                             int maxAmount)

  Deprecated.
  Returns a list of results ending with the element right before the provided result (the returned List is exclusive). At most 'maxAmount' elements are in the returned List, but the lenght of the result might be smaller if no more applicable elements are available. Note that the order of the result is equal to the order of the results of other methods of this class: the last element in the returned List immediately preceeds the element denoted by the 'result' parameter.

  Parameters:
    `result` - The element preceding the last element returned by this function.
    `maxAmount` - The length of the List that is being returned.
  Returns:
    A List of elements that are exactly before the element that's provided as a parameter.
  Throws:
    `NullPointerException` - if the result does not exist in the result set.

### getBefore

    public abstract List<E> getBefore(String uid,
                                      int maxAmount)

  Deprecated.
  Returns a list of results ending with the element right before the element identified by the provided UID (the returned List is exclusive). At most 'maxAmount' elements are in the returned List, but the lenght of the result might be smaller if no more applicable elements are available. Note that the order of the result is equal to the order of the results of other methods of this class: the last element in the returned List immediately preceeds the element denoted by the 'result' parameter.

  Parameters:
    `uid` - The UID of the element preceding the last element returned by this function.
    `maxAmount` - The length of the List that is being returned.
  Returns:
    A List of elements that are exactly before the element that's provided as a parameter.
  Throws:
    `NullPointerException` - if there is no result in the result set that matches the UID.

### getFirst

    public abstract List<E> getFirst(int maxAmount)

  Deprecated.
  Returns the first elements from this result set.

  Parameters:
    `maxAmount` - the number of elements to return.

If the difference between the startIndex and the index of the last element in the entire resultset is smaller than the size supplied in the 'amount' parameter, the length of the returned list will be smaller than the 'amount' paramater. If the supplied index is equal to, or larger than the size of the result set, an empty List is returned.

  Parameters:
    `fromIndex` - The index of the first element to be returned.
    `maxAmount` - The maximum number of elements to return.
  Returns:
    A list of elements starting with (inclusive) the element referenced by 'fromIndex'. An empty List if startIndex is equal to or bigger than the size of this entire result set.

### getUID
