Method Details

[hide private]

init(self, name)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

str(self)
(Informal representation operator)

source code

str(x)

Overrides: object.__str__: (inherited documentation)

make_ready(self)

source code

Get a Node ready for evaluation.

This is called before the Taskmaster decides if the Node is up-to-date or not. Overriding this method allows for a Node subclass to be disambiguated if necessary, or for an implicit source builder to be attached.

Overrides: Node.make_ready: (inherited documentation)

really_build(self, **kw)

source code

Actually build the node.

This is called by the Taskmaster after it's decided that the Node is out-of-date and must be rebuilt, and after the prepare() method has gotten everything, uh, prepared.

This method is called from multiple threads in a parallel build, so only do thread safe stuff here. Do thread unsafe stuff in built().

is_up_to_date(self)

source code

Alternate check for whether the Node is current: If all of our children were up-to-date, then this Node was up-to-date, too.

The SCons.Node.Alias and SCons.Node.Python.Value subclasses rebind their current() method to this method.

Overrides: Node.is_up_to_date

get_contents(self)

source code

The contents of an alias is the concatenation of the content signatures of all its sources.

Overrides: Node.get_contents

build(self)

source code

A "builder" for aliases.

Overrides: Node.build

get_csig(self)

source code

Generate a node's content signature, the digested signature of its content.

node - the node cache - alternate node to use for the signature cache returns - the content signature

Overrides: Node.get_csig
