        void setDefaultSequence​(Sequence sequence)
        Set default sequence. The sequence should have a unique name that shouldn't be altered after the sequence has been set: don't do: getDefaultSequence().setName(newName)). Default constructors for Sequence subclasses set name to "SEQ".

      • addSequence

        Add sequence. The sequence should have a unique name that shouldn't be altered after the sequence has been added - don't do: getSequence(name).setName(newName)) Don't use if the session is connected.

        Remove sequence corresponding to the name (the sequence was added through addSequence method) Don't use if the session is connected.

      • removeAllSequences

        void removeAllSequences()
        Remove all sequences that were added through addSequence method.

      • getSequences

        java.util.Map getSequences()

        INTERNAL: Used only for reading from XML.

      • usesPlatformDefaultSequence

        boolean usesPlatformDefaultSequence()
