# All True This function block checks whether all elements in a provided boolean list are true. It is useful for combining multiple checks into a single pass/fail result for downstream logic or UI feedback. ## 📥 Inputs `Boolean List` This input accepts a list of boolean values (True / False). Each element is evaluated. ## 📤 Outputs `All True` This output produces a single boolean: True when all provided elements are True, otherwise False. ## 🕹️ Controls No interactive controls are exposed for this block. ## 🎯 Features * Simple, single-purpose logic check for lists of booleans. * Works with lists coming from other blocks (including lists produced by batch or parsing operations). * Safe handling for missing or invalid list elements — returns False when the list contains None or any False values. ## 📝 Usage Instructions 1. Provide a boolean list to the `Boolean List` input (for example, outputs from several checks). 2. Read the single boolean from the `All True` output to decide a combined pass/fail action. ## 📊 Evaluation On execution the block inspects the provided list: if every element is True the block outputs True; if any element is False or missing the block outputs False. ## 💡 Tips and Tricks * Use with `Logic Input` to create manual test lists for debugging or operator-controlled checks. * Combine with `And` / `Or` to create more complex logical expressions before producing the final list. * Pre-filter inputs with `Exclude Nones` to remove empty values that might unintentionally fail the check. * Use `List Operations` or `Get Element` to build or inspect lists before feeding them here. * In batch scenarios, use `Batch Processing` / `Debatch` and `Get Batch Size` to control how lists are constructed and validated. ## 🛠️ Troubleshooting * No output or unexpected False: Verify that the input list contains only boolean values and that there are no unexpected None elements. * Feeding non-list data: Ensure the producer block outputs a list (use `List Operations` or `Mux` / `Demux` helpers to format data as lists). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
