This is the super-class for all
Alternative
events selectable by a process.
Description
Guard defines an abstract interface to be implemented by events competing for selection by a process executing anAlternative
. Its methods have
only package visibility within org.jcsp.lang and are of no concern to
users of this package. Currently, JCSP supports channel inputs, accepts,
timeouts and skips as guards.
Note: for those familiar with the occam multiprocessing language, classes implementing Guard correspond to process guards for use within ALT constructs.
