Class SpecialAttrWrapper

source code

This is a wrapper for what we call a 'Node special attribute.'
This is any of the attributes of a Node that we can reference from
Environment variable substitution, such as $TARGET.abspath or
$SOURCES[1].filebase.  We implement the same methods as Literal
so we can handle special characters, plus a for_signature method,
such that we can return some canonical string during signature
calculation to avoid unnecessary rebuilds.



Instance Methods [hide private]
 
__init__(self, lstr, for_signature=False)
The for_signature parameter, if supplied, will be the canonical string we return from for_signature().
