Inherits from
- HasTraits: enthought.traits.has_traits.HasTraits
Attributes
- all_outputs
all_outputs = Property(Instance(set))
- ast
The AST that represents our behavior
ast = Instance(Node)
- conditional_outputs
conditional_outputs = Instance(set)
- filename
The name of the file this block represents, if any. For blocks that aren't files, the default value just shows repr(self). Annotates tracebacks.
filename = Instance(str)
- inputs
Input and output parameters
inputs = Instance(set)
- no_filenames_in_tracebacks
Enabling this makes tracebacks less useful but speeds up Block.execute. The problem is that a code object has a unique filename ('co_filename'), so we can compile all of our sub-blocks' ASTs into a single code object only if we ignore the fact that they might each come from different files.
no_filenames_in_tracebacks = Bool(False)
- outputs
outputs = Instance(set)
- sub_blocks
The sequence of sub-blocks that make up this block, if any. If we don't decompose into sub-blocks, 'sub_blocks' is None. sub_blocks = Either(List(__this), None) # FIXME
sub_blocks = Either(List(Any), None)
- uuid
A unique identifier
uuid = Instance(UUID)

- __hash__(self)
- __init__(self, x = (), file = None, **kw)
- __repr__(self)
- __str__(self)
- execute(self, context)
- from_file(cls, f)
Create a Block from a source file.
- from_string(cls, s)
Create a Block from a code string.
- restrict(self, inputs = (), outputs = ())
The minimal sub-block that computes 'outputs' from 'inputs'.
'inputs' and 'outputs' must be subsets of 'self.inputs' and 'self.outputs', respectively.
