basic-target class basic-target : abstract-target { rule __init__ ( name : project : sources * : requirements * : default-build * : usage-requirements * ) rule generate ( property-set ) rule construct ( name : source-targets * : property-set ) # Methods inherited from abstract-target rule name ( ) rule project ( ) rule location ( ) rule full-name ( ) } Implements the most standard way of constructing main target alternative from sources. Allows sources to be either files or other main targets and handles generation of those dependency targets. rule __init__ ( name : project : sources * : requirements * : default-build * : usage-requirements * ) name The name of the target project The project in which the target is declared. generate Basic Target Method rule generate ( property-set ) Overrides abstract-target.generate. Determines final build properties, generates sources, and calls construct. This method should not be overridden. On success, returns: a property-set with the usage requirements to be applied to dependents a list of produced virtual targets, which may be empty. construct Basic Target Method rule construct ( name : source-targets * : property-set ) Constructs virtual targets for this abstract target. Returns a usage-requirements property-set and a list of virtual targets. Should be overriden in derived classes.
