Method Detail

asCollection

public Collection<RecordType> asCollection()
                                    throws org.apache.guacamole.GuacamoleException

Description copied from interface: ActivityRecordSet

Returns all records within this set as a standard Collection.

Specified by:

asCollection in interface ActivityRecordSet<RecordType extends ActivityRecord>

Returns:

A collection containing all records within this set.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the records within this set.

contains

public ActivityRecordSet<RecordType> contains(String value)
                                       throws org.apache.guacamole.GuacamoleException

Description copied from interface: ActivityRecordSet

Returns the subset of records which contain the given value. The properties and semantics involved with determining whether a particular record "contains" the given value is implementation dependent. This function may affect the contents of the current ActivityRecordSet. The contents of the current ActivityRecordSet should NOT be relied upon after this function is called.

Specified by:

contains in interface ActivityRecordSet<RecordType extends ActivityRecord>

Parameters:

value - The value which all records within the resulting subset should contain.

Returns:

The subset of records which contain the specified value.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while restricting the current subset.

limit

public ActivityRecordSet<RecordType> limit(int limit)
                                    throws org.apache.guacamole.GuacamoleException

Description copied from interface: ActivityRecordSet

Returns the subset of records containing only the first limit records. If the subset has fewer than limit records, then this function has no effect. This function may also affect the contents of the current ActivityRecordSet. The contents of the current ActivityRecordSet should NOT be relied upon after this function is called.

Specified by:

limit in interface ActivityRecordSet<RecordType extends ActivityRecord>

Parameters:

limit - The maximum number of records that the new subset should contain.

Returns:

The subset of records that containing only the first limit records.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while limiting the current subset.

sort

public ActivityRecordSet<RecordType> sort(ActivityRecordSet.SortableProperty property,
                                          boolean desc)
                                   throws org.apache.guacamole.GuacamoleException

Description copied from interface: ActivityRecordSet

Returns a ActivityRecordSet containing identically the records within this set, sorted according to the specified criteria. The sort operation performed is guaranteed to be stable with respect to any past call to sort(). This function may also affect the contents of the current ActivityRecordSet. The contents of the current ActivityRecordSet should NOT be relied upon after this function is called.

Specified by:

sort in interface ActivityRecordSet<RecordType extends ActivityRecord>

Parameters:

property - The property by which the records within the resulting set should be sorted.

desc - Whether the records should be sorted according to the specified property in descending order. If false, records will be sorted according to the specified property in ascending order.

Returns:

The ActivityRecordSet, sorted according to the specified criteria.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while sorting the current subset, or if the given property is not supported by the implementation.
