CustomAttributeSet ECClass Retrieve all custom attributes in the current class and its bases. getInheritedProperty(name: string): Promise<undefined | Property> ECClass Searches the base class, if one exists, for the property with the name provided. getInheritedPropertySync(name: string): undefined | Property ECClass Searches the base class, if one exists, for the property with the name provided. getProperties(resetCache: boolean = false): Promise<Property[]> ECClass Iterates all properties, including the ones merged from base classes and mixins. getPropertiesSync(resetCache: boolean = false): Property[] ECClass Iterates all properties, including the ones merged from base classes and mixins. getProperty(name: string, includeInherited: boolean = false): Promise<undefined | Property> ECClass
