Bases: onegov.core.collection.GenericCollection[onegov.activity.models.Occasion]

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

static to_half_open_interval(lower: int, upper: int) → onegov.activity.types.BoundedIntegerRange

Postgres coerces ranges internally to be half-open in an effort to canonize these ranges. This function does the same by taking a closed interval and turning it into a half-open interval of the NumericRange type.
