  - ### Method Detail

    - #### int complete(java.lang.String buffer, int cursor, java.util.List candidates)

      Check whether the whole buffer matches the configured pattern. If it does, the buffer is added to the `candidates` list (which indicates acceptance of the buffer string) and returns 0, i.e. the start of the buffer. This mimics the behaviour of SimpleCompletor.

      If the buffer doesn't match the configured pattern, this returns -1 and the `candidates` list is left empty.
