| The node can have a persistent input: the input values are retained after a node-red reboot. That means, that if you reboot your node-red, you don't need to wait all inputs to arrive and initialize the node, before the node can output a payload.<br/> | |||
| You can also set the default values of the topic inputs. | |||
| ## ADDITIONAL FUNCTIONS | |||
| * Filter ouput results (outputs only true or trye/false) | |||
| * Trigger mode selection (Can output a payload only by single input's topic trigger and after evaluation ot other inputs, or can oputput a payload by change of every input) | |||
| ## CONFIGURATION | |||
| ***Number of different topics to evaluate*** | |||
| **Number of different topics to evaluate** | |||
| Set the number of different topics to be evaluated. The node will output a message to the flow, after this number of different topics arrives.<br/> | |||
| *Remember: each input topic must be different. For example, if you set this field to 3, the node expects 3 different topics.* | |||
| ***Filter output result*** | |||
| <ol> | |||
| <li>Output both 'true' and 'false' results: Standard behaviour, the node will output <b>true</b> and <b>false</b> whenever it receives an input and calculate the boolean logics as output.</li> | |||
| <li>Output only 'true' results: whenever the node receives an input, it outputs a payload <b>true</b> only if the result of the logic is true. <b>False</b> results are filtered out.</li> | |||
| </ol> | |||
| <br/> | |||
| **Filter output result** | |||
| - Output both 'true' and 'false' results: Standard behaviour, the node will output <b>true</b> and <b>false</b> whenever it receives an input and calculate the boolean logics as output. | |||
| - Output only 'true' results: whenever the node receives an input, it outputs a payload <b>true</b> only if the result of the logic is true. <b>False</b> results are filtered out. | |||
| **Trigger mode** | |||
| <ol> | |||
| <li>All topics: standard behaviour, the node will evaluate each input topic and ouputs the values. At each input change, it will output a msg on the flow.</li> | |||
| <li>Single topic + eval other inputs: the node evaluates all the input topics, but only whenever it receives a msg input with the **specified topic** (having payload **true**), it outputs a msg to the flow.</li> | |||
| </ol> | |||
| - All topics: standard behaviour, the node will evaluate each input topic and ouputs the values. At each input change, it will output a msg on the flow. | |||
| - Single topic + eval other inputs: the node evaluates all the input topics, but only whenever it receives a msg input with the **specified topic** (having payload **true**), it outputs a msg to the flow. | |||
| **If input states are undefined** | |||
| Every time you create a node or modify the node, all inputs are set to undefined. This means that the node will wait the arrive of all topics (for example 3 topics, if you've selected 3 topics in the option), before it can output a payload. This can be a problem if your logic must be operative as soon as you deploy the flow. To overcome this problem, you can "initialize" all the undefined inputs with True or False. | |||
| <ol> | |||
| <li>Leave undefined: Standard behaviour, the node will wait all the "undefined" topics to arrive, then starts a flow with the result.</li> | |||
| <li>True or False: The node is immediately operative, by force the initialization of the "undefined" inputs with "true" or "false".</li> | |||
| </ol> | |||

| - Leave undefined: Standard behaviour, the node will wait all the "undefined" topics to arrive, then starts a flow with the result. | |||
| - True or False: The node is immediately operative, by force the initialization of the "undefined" inputs with "true" or "false". | |||
| **Remember latest input values after reboot** | |||
| If checked, the input values are retained after a node-red reboot. That means, that if you reboot your node-red, you don't need to wait all inputs to arrive and initialize the node, before the node can output a payload.<br/> | |||
| Every time you modify the node's config, <b>the retained values are cleared</b>.<br/> | |||
| All incoming msg.payloads are converted into a boolean value according to the following rules (this applies to all boolean logic nodes): | |||
| <ol> | |||
| <li>Boolean values are taken as-is.</li> | |||
| <li>For numbers, 0 evaluates to false, all other numbers evaluates to true.</li> | |||
| <li>Strings are converted to numbers if they match the format of a decimal value, then the same rule as for numbers are applied. If it does not match, it evaluates to false. Also, the string "true" evaluates to true.</li> | |||
| </ol> | |||

| The XOR operation operates in a one, and only one mode, i.e. (A ^ B) ^ C ... ^ n | |||
