Class SignBase

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

Parameters:

• formalism (FormalismBase subclass) - the formalism of the subclass.
• category (Category) - the top level node of the category instance.
• semantics (Semantics) - the semantics part of the sign
• derivation_trace (DerivationTrace) - a derivation trace to store how the sign was derived (optional).

Returns:

a Latex source representation of the object.

Format the sign as a string for display in a list of results. By default, this just uses the class' str(), but subclasses may provide an alternative format if required (you may want signs to look different in results and in, e.g., chart representation).

Same as format_result, but returns latex source. By default uses the class' to_latex method.

Given a dictionary of features, applies any changes to this sign that need to be made before it is added to the chart on the basis of surface-level features (e.g. pitch, time).

Must be implemented by subclasses. Adds timing information to components such that the start time of the whole sign is encoded as the given time.

Must be implemented by subclasses. Adds duration information to all components that store durations.

Returns True if the given rule instance has been applied to this sign previously in the parse. If the rule is binary, other_input should be given and this sign is assumed to be the leftmore input.

Keeps a note that the given rule was applied to this sign. If it is a binary rule, you must also specify what the second input was.
