Package SCons :: Module Executor :: Class Executor

Class Executor

A class for controlling instances of executing an action.

This largely exists to hold a single association of an action,
environment, list of environment override dictionaries, targets
and sources for later processing as needed.

add_sources(self, sources)

source code

Add source files to this Executor's list.  This is necessary
for "multi" Builders that can be called repeatedly to build up
a source file list for a given target.

get_contents(self)

source code

Fetch the signature contents.  This is the main reason this
class exists, so we can compute this once and cache it regardless
of how many target or source Nodes there are.

get_timestamp(self)

source code

Fetch a time stamp for this Executor.  We don't have one, of
course (only files do), but this is the interface used by the
timestamp module.

scan(self, scanner, node_list)

source code

Scan a list of this Executor's files (targets or sources) for
implicit dependencies and update all of the targets with them.
This essentially short-circuits an N*M scan of the sources for
each individual target, which is a hell of a lot more efficient.

get_implicit_deps(self)

source code

Return the executor's implicit dependencies, i.e. the nodes of
the commands to be executed.
