genplanner.TerritoryZone

class genplanner.TerritoryZone(kind, name=<property object>, min_block_area=20000)

A concrete territorial zone definition.

TerritoryZone represents a specific zone within a territory plan. It has:

• a kind (from genplanner.zones.territory_zones.TerritoryZoneKind),

• a human-readable name,

• a minimum block area constraint (min_block_area).

The zone’s min_area is defined as min_block_area, making it compatible with generic area constraints used elsewhere in the pipeline.

Variables:

• kind (genplanner.zones.territory_zones.TerritoryZoneKind) – Zone kind (Enum or a value convertible to it).

• name (str) – Non-empty zone name.

• min_block_area (float) – Minimum allowed area for generated blocks for this zone. Must be > 0.

Raises:

ValueError – If kind is invalid, name is empty, or min_block_area <= 0.

property min_area

Minimum area constraint for this zone.

Returns:

Minimum block area.

Return type:

float

validate()

Validate and normalize zone fields.

Ensures:

• kind is a TerritoryZoneKind (attempts coercion from string/other),

• name is a non-empty string,

• min_block_area is a positive number.

Raises:

ValueError – If kind cannot be coerced, name is empty, or min_block_area <= 0.
