equalByKey(thisSchemaItem: SchemaItem, thatSchemaItemOrKey?: SchemaItemKey | SchemaItem): boolean Static Inherited ECClass Indicates if the two SchemaItem objects are equal by comparing their respective key properties.
parseFullName(fullName: string): [string, string] Static Inherited ECClass Parses the given full name, {schemaName}.{schemaItemName} or {schemaName}:{schemaItemName}, into two separate strings.
