:string

className <readonly>

The name of the subclass for this object instance.

This name must match the name of this class within the PD.Registry. Thus, the base implementation simply references this.constructor.getClassName() to ensure that this is always the case even for subclasses. As a result, there is rarely any need to override this method.

This property is used when copying, storing and exporting data for subclass instances to ensure that they are recreated as instances of the right class.

The distance between front and rear of the appliance, defaults to 600mm or 24".

This description is typically used to provide additional information about the product to other team members, such as its reasons for selection. important features, specifications and/or intended use.

iconName <readonly>

The name of the SVG icon to associate with this object instance.

This name should match the name of the icon associated with this class within the PD.Registry. Thus, the default implementation simply references this.constructor.getClassName() to ensure that this is always the case, even for subclasses. However, you can override this property if you want a different icon dependant on other properties of the class instance, as shown in the example below.

Type
  • string
Inherited From:
Overrides:
Example
// Overriding the icon name.

MyElements.Table = class extends PD.Base {
    /// ...
    get iconName() {
        if (this.hasRoundTop) return 'MyElements.Table.Round';
        return this.constructor.getClassName();
    };

Type

:boolean

isLocked

Whether or not this component's parameters are fixed.

This property is used by the UI and framework to indicate that the component's parameters are fixed and therefore not editable. It is typically set by a 3rd-party manufacturer or supplier on products that they can only provide in one configuration.

For example, there is no point specifying a particular manufacturer's fridge and then adjusting its width to fit a hole in your cabinetry if that manufacturer cannot actually supply a fridge of that width.

Thus, when this property is true, you will not be able to edit the parameters, but you can always duplicate the component (or its configuration), but without the supplier details if you really do want to modify it.

Type
  • boolean

Type
  • string

supplier

The product supplier/manufacturer, defaults to null.

This property contains details of the supplier or manufacturer of this product or component. Multiple components can share the same supplier instance to avoid unnecessary duplication of data.

Parameters:
Name Type Description

flip boolean

Whether or not to flip surface orientations.
Inherited From:

Type
Array

getNameAndSupplierParameters()

Provides a list of dynamic parameter groups for the component name, description and supplier.

See the PD.Base#getDynamicParameters method for more details.

Inherited From:
Overrides:
Returns:

Returns an array of PD.ParamGroup objects.

Type
Array

hasMethod(component, methodName)

Determines if this component has a callable method with the given name.

This method is useful for checking if the component has a particular method before attempting to call it, thereby avoiding potential runtime errors. It is used within the framework to check for the presence of life-cycle methods in an element's type component before delegating them.

Parameters:
Name Type Description
component BIM.Component

The component to check.
methodName string

The case-sensitive name of the function/method to check for.
Inherited From:
Overrides:
Returns:

Returns true if the component is valid and has the function name as a method, otherwise false.

Type
boolean

isCompatibleWith(obj)

Determines if this component can be added to the given entity.

Whilst a small number of components may be compatible with multiple entity types, most components are designed to be used only by a specific entity type, and will not allow you to assign them to an incompatible entity.

Parameters:
Name Type Description
obj BIM.ENTITY | BIM.Entity

The entity type or object instance to check for compatibility with.
Inherited From:
Overrides:
Returns:

Returns true if the component can be added to the object, otherwise false.

Type
boolean

updateDynamicParameters(param, group)

Sets the dynamic parameter value and returns true if it changed.

Most subclasses don't need to override this method as it automatically detects changes and rebuilds the element/component and model when required. However, if you do need to add your own custom logic or intercept the return value, please read the following examples carefully and use whichever best suits your needs.

NOTE: When overriding this method, you may not want to call super.updateDynamicParameters(param, group) as the parent class may have added its own logic that may interfere with what you want to do. Instead, either use the static PD.Base.updateDynamicParametersOnHost method to check if the value changed, or base it on the third example which replicates the code in that static method.

Parameters:
Name Type Description
param PD.Parameter

The dynamic parameter that changed.
group PD.ParamGroup

The group that the dynamic parameter belongs to.
Inherited From:
Overrides:
Returns:

Returns true if the value actually changed.

Type
boolean

     /// When you want parent class to use its logic.

     /// `group.getTarget() || this` twice.

             /// If no level meshes or other elements are affected,
             /// simply update the target locally and return false.
             this.myOwnMeshThatIsUpdatedDuringRebuild.update();

             /// Update selection meshes if the
             /// element's highlight geometry changed.
