Constructor Details

#initialize(*args) ⇒ Marker

args can be any of these forms:

  • (symbol, slave = Relisp.default_slave)

  • (slave = Relisp.default_slave)

When a symbol is given it is considered to be the name of a pre-existing marker in the slave process. Otherwise a new, empty marker is created (make-marker).
