Struct RepresentationContext 

pub struct RepresentationContext<'m> { /* private fields */ }

One IfcGeometricRepresentationContext or its sub-context.

Implementations

impl<'m> RepresentationContext<'m>

pub fn new(id: EntityId, entity: &'m Entity) -> Self

Wrap an entity assumed to be a representation context.

pub fn id(&self) -> EntityId

This context’s entity id.

pub fn is_sub_context(&self) -> bool

Whether this is an IfcGeometricRepresentationSubContext.

pub fn identifier(&self) -> Option<String>

ContextIdentifier, e.g. Body, Axis, Plan.

pub fn context_type(&self) -> Option<String>

ContextType, e.g. Model, Plan, Design.

pub fn parent(&self) -> Option<EntityId>

The parent context of a sub-context, if it declares one.

pub fn target_scale(&self) -> Option<f64>

TargetScale, e.g. 0.01 for 1:100. Sub-contexts only.

pub fn target_view(&self) -> Option<TargetView>

TargetView. Sub-contexts only; None on a root context.

pub fn is_plan_view(&self) -> bool

Whether this context is authored for plan drawing.

impl RepresentationContext<'_>

pub fn precision(&self, model: &Model) -> Option<f64>

Precision, resolved through ParentContext when written as *.

The value a tolerance-sensitive consumer needs; reading the slot directly on a sub-context yields the DERIVED marker instead.

pub fn coordinate_space_dimension(&self, model: &Model) -> Option<i64>

CoordinateSpaceDimension, resolved through ParentContext.

pub fn world_coordinate_system(&self, model: &Model) -> Option<EntityId>

WorldCoordinateSystem, resolved through ParentContext.

Without this a sub-context appears to have no placement and geometry authored into it lands at the wrong origin.

pub fn true_north(&self, model: &Model) -> Option<EntityId>

TrueNorth, resolved through ParentContext.

Trait Implementations

impl<'m> Clone for RepresentationContext<'m>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'m> Copy for RepresentationContext<'m>

impl<'m> Debug for RepresentationContext<'m>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
