Module Environment

source code

SCons.Environment

Base class for construction Environments. These are the primary objects used to communicate dependency and construction information to the build engine.

Keyword arguments supplied when the construction Environment is created are construction variables used to initialize the Environment

Classes [hide private]
  _Null
  _null
  MethodWrapper
A generic Wrapper class that associates a method (which can actually be any callable) with an object. As part of creating this MethodWrapper object an attribute with the specified (by default, the name of the supplied method) is added to the underlying object. When that new "method" is called, our __call__() method adds the object as the first argument, simulating the Python behavior of supplying "self" on method calls.
  BuilderWrapper
A MethodWrapper subclass that that associates an environment with a Builder.
  BuilderDict
This is a dictionary-like class used by an Environment to hold the Builders. We need to do this because every time someone changes the Builders in the Environment's BUILDERS dictionary, we must update the Environment's attributes.
  SubstitutionEnvironment
Base class for different flavors of construction environments.
  Base
Base class for "real" construction Environments. These are the primary objects used to communicate dependency and construction information to the build engine.
  OverrideEnvironment
A proxy that overrides variables in a wrapped construction environment by returning values from an overrides dictionary in preference to values from the underlying subject environment.
  Environment
Base class for "real" construction Environments. These are the primary objects used to communicate dependency and construction information to the build engine.
