Methods
byEntity()
byEntity(
group
):void
Classifies fragments based on their entity type.
Parameters
Parameter | Type | Description |
---|---|---|
group | FragmentsGroup | The FragmentsGroup containing the fragments to be classified. |
Returns
void
Remarks
This method iterates through the relations of the fragments in the provided group,
and classifies them based on their entity type.
The classification is stored in the list.entities
property,
with the entity type as the key and a map of fragment IDs to their respective express IDs as the value.
Throws
Will throw an error if the fragment ID is not found.
byIfcRel()
byIfcRel(
group
,ifcRel
,systemName
):Promise
<void
>
Classifies fragments based on a specific IFC relationship.
Parameters
Parameter | Type | Description |
---|---|---|
group | FragmentsGroup | The FragmentsGroup containing the fragments to be classified. |
ifcRel | number | The IFC relationship number to classify fragments by. |
systemName | string | The name of the classification system to store the classification. |
Returns
Promise
<void
>
Remarks
This method iterates through the relations of the fragments in the provided group,
and classifies them based on the specified IFC relationship.
The classification is stored in the list
property under the specified system name,
with the relationship name as the class name and a map of fragment IDs to their respective express IDs as the value.
Throws
Will throw an error if the fragment ID is not found or if the IFC relationship is not valid.
byModel()
byModel(
modelID
,group
):void
Classifies fragments based on their modelID.
Parameters
Parameter | Type | Description |
---|---|---|
modelID | string | The unique identifier of the model to classify fragments by. |
group | FragmentsGroup | The FragmentsGroup containing the fragments to be classified. |
Returns
void
Remarks
This method iterates through the fragments in the provided group,
and classifies them based on their modelID.
The classification is stored in the list.models
property,
with the modelID as the key and a map of fragment IDs to their respective express IDs as the value.
byPredefinedType()
byPredefinedType(
group
):Promise
<void
>
Classifies fragments based on their PredefinedType property.
Parameters
Parameter | Type | Description |
---|---|---|
group | FragmentsGroup | The FragmentsGroup containing the fragments to be classified. |
Returns
Promise
<void
>
Remarks
This method iterates through the properties of the fragments in the provided group,
and classifies them based on their PredefinedType property.
The classification is stored in the list.predefinedTypes
property,
with the PredefinedType as the key and a map of fragment IDs to their respective express IDs as the value.
Throws
Will throw an error if the fragment ID is not found.
bySpatialStructure()
bySpatialStructure(
model
,config
):Promise
<void
>
Classifies fragments based on their spatial structure in the IFC model.
Parameters
Parameter | Type | Description |
---|---|---|
model | FragmentsGroup | The FragmentsGroup containing the fragments to be classified. |
config | object | The configuration for the classifier. It includes "useProperties", which is true by default (if false, the classification will use the expressIDs instead of the names), and "isolate", which will make |
the classifier just pick the WEBIFC categories provided. | ||
config.isolate ? | Set <number > | - |
config.systemName ? | string | - |
config.useProperties ? | boolean | - |
Returns
Promise
<void
>
Remarks
This method iterates through the relations of the fragments in the provided group,
and classifies them based on their spatial structure in the IFC model.
The classification is stored in the list
property under the system name "spatialStructures",
with the relationship name as the class name and a map of fragment IDs to their respective express IDs as the value.
Throws
Will throw an error if the fragment ID is not found or if the model relations do not exist.
dispose()
dispose():
void
Returns
void
Implementation of
find()
find(
filter
?):FragmentIdMap
Finds and returns fragments based on the provided filter criteria. If no filter is provided, it returns all fragments.
Parameters
Parameter | Type | Description |
---|---|---|
filter ? | object | An optional object containing filter criteria. |
The keys of the object represent the classification system names, | ||
and the values are arrays of class names to match. |
Returns
FragmentIdMap
A map of fragment GUIDs to their respective express IDs, where the express IDs are filtered based on the provided filter criteria.
Throws
Will throw an error if the fragments map is malformed.

remove()
remove(
guid
):void
Removes a fragment from the classification based on its unique identifier (guid). This method iterates through all classification systems and classes, and deletes the fragment with the specified guid from the respective group.
