Abstract base class for generic types.

A generic type is typically declared by inheriting from this class parameterized with one or more type variables. For example, a generic mapping type might be defined as:

class Mapping(Generic[KT, VT]):
    def __getitem__(self, key: KT) -> VT:
        ...
    # Etc.

This class can then be used as follows:

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT:
    try:
        return mapping[key]
    except KeyError:
        return default

Parameters:

grammar (Grammar) – The grammar to use in the mapping
max_depth (int) – the maximum depth when performing the mapping
initialization_mode (InitializationMethodType) – method to create individuals in the mapping (e.g., pi_grow, full, grow)
gene_length (int)
