Method Details [hide private]

get_name(self, env)

source code 
Attempts to get the name of the Builder.

Look at the BUILDERS variable of env, expecting it to be a
dictionary containing this Builder, and return the key of the
dictionary.  If there's no key, then return a directly-configured
name (if there is one) or the name of the class (by default).

add_emitter(self, suffix, emitter)

source code 
Add a suffix-emitter mapping to this Builder.

This assumes that emitter has been initialized with an
appropriate dictionary type, and will throw a TypeError if
not, so the caller is responsible for knowing that this is an
appropriate method to call for the Builder in question.

add_src_builder(self, builder)

source code 

Add a new Builder to the list of src_builders.

This requires wiping out cached values so that the computed
lists of source suffixes get re-calculated.

_get_sdict(self, env)

source code 

Returns a dictionary mapping all of the source suffixes of all
src_builders of this Builder to the underlying Builder that
should be called first.

This dictionary is used for each target specified, so we save a
lot of extra computation by memoizing it for each construction
environment.

Note that this is re-computed each time, not cached, because there
might be changes to one of our source Builders (or one of their
source Builders, and so on, and so on...) that we can't "see."

The underlying methods we call cache their computed values,
though, so we hope repeatedly aggregating them into a dictionary
like this won't be too big a hit.  We may need to look for a
better way to do this if performance data show this has turned
into a significant bottleneck.

get_src_builders(self, env)

source code 

Returns the list of source Builders for this Builder.

This exists mainly to look up Builders referenced as
strings in the 'BUILDER' variable of the construction
environment and cache the result.

subst_src_suffixes(self, env)

source code 

The suffix list may contain construction variable expansions,
so we have to evaluate the individual strings.  To avoid doing
this over and over, we memoize the results for each construction
environment.

src_suffixes(self, env)

source code 

Returns the list of source suffixes for all src_builders of this
Builder.

This is essentially a recursive descent of the src_builder "tree."
(This value isn't cached because there may be changes in a
src_builder many levels deep that we can't see.)
