The free properties can contains several lines. The method `getFreeProperty()` of `ITangoDB` should return an array of strings instead of a string. To ensure compatibility and avoid breaking existing code, a new method named `getFreePropertyArray()` needs to be introduced. Currently, it seems that only the `NoCacheDatabase` class is handling the database extraction. Below is a proposed implementation for the new method: ```java public String[] getFreePropertyArray(final String name, final String propertyName) throws DevFailed { // Prepare input data final DeviceData argin = new DeviceData(); argin.insert(new String[] { name, propertyName }); // Invoke the database command final DeviceData deviceData = database.command_inout("DbGetProperty", argin); String[] result = new String[0]; // Initialize an empty array // Extract the array and check its length String[] extractedArray = deviceData.extractStringArray(); if (extractedArray.length > 4) { // Copy a sub-array from index 4 to the end result = Arrays.copyOfRange(extractedArray, 4, extractedArray.length); } return result; } ```
