Interface ActivityRecordSet<RecordType extends ActivityRecord>

    • Method Detail

      • asCollection

        Collection<RecordType> asCollection()
                                     throws org.apache.guacamole.GuacamoleException
        Returns all records within this set as a standard Collection.
        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.
      • get

        default RecordType get​(String identifier)
                        throws org.apache.guacamole.GuacamoleException
        Returns the record having the given unique identifier, if records within this set have unique identifiers. If records within this set do not have defined unique identifiers, this function has no effect.
        Parameters:
        identifier - The unique identifier of the record to retrieve.
        Returns:
        The record having the given unique identifier, or null if there is no such record.
        Throws:
        org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the record.
      • contains

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

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

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