Struct AlignmentHierarchy 

#[non_exhaustive]
pub struct AlignmentHierarchy {
    pub alignment: EntityId,
    pub parent: Option<EntityId>,
    pub horizontal: Vec<EntityId>,
    pub vertical: Vec<EntityId>,
    pub cant: Vec<EntityId>,
    pub referents: Vec<EntityId>,
    pub children: Vec<EntityId>,
    pub positioned: Vec<EntityId>,
}

What one IfcAlignment is made of, as stated by its relationships.

Every list keeps the order the file states: nesting order for layouts and referents, relationship order for children and positioned products. A list may be empty; how many layouts of a kind an alignment may have is a question the sole_* methods answer with a typed refusal.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

alignment: EntityId

The IfcAlignment described.

parent: Option<EntityId>

The IfcAlignment that aggregates this one, when it is a child. None for an alignment aggregated directly under the project (or not aggregated at all).

horizontal: Vec<EntityId>

Nested IfcAlignmentHorizontal layouts.

vertical: Vec<EntityId>

Nested IfcAlignmentVertical layouts.

cant: Vec<EntityId>

Nested IfcAlignmentCant layouts.

referents: Vec<EntityId>

Nested IfcReferents, in nesting order.

children: Vec<EntityId>

Child IfcAlignments aggregated under this one.

positioned: Vec<EntityId>

Products this alignment positions through IfcRelPositions.

Implementations

impl AlignmentHierarchy

pub fn sole_horizontal(&self) -> AlignmentResult<Option<EntityId>>

The alignment’s own horizontal layout: None when it nests none (a child reusing its parent’s, see AlignmentView::governing_horizontal).

Errors

AlignmentError::SemanticViolation when it nests several.

pub fn sole_vertical(&self) -> AlignmentResult<Option<EntityId>>

The alignment’s vertical layout, None when it nests none.

Errors

AlignmentError::SemanticViolation when it nests several.

pub fn sole_cant(&self) -> AlignmentResult<Option<EntityId>>

The alignment’s cant layout, None when it nests none.

Errors

AlignmentError::SemanticViolation when it nests several.
