Documentation for LayerUtility: BooleanOperator Node

Overview

The LayerUtility: BooleanOperator node is a versatile component within the ComfyUI framework designed to perform various boolean operations and comparisons between two inputs. This makes it highly useful for decision-making processes within workflows, determining conditional paths based on input values.

Functionality

Purpose

This node evaluates two inputs based on a specified boolean operation or comparison operator. Depending on the selected operator, it returns a boolean value that represents the result of the operation. This can be useful in various scenarios, such as filtering data, validating conditions, or directing workflow execution paths based on input criteria.

Inputs

The LayerUtility: BooleanOperator node accepts the following inputs:

Required Inputs

1. a: This is the first input, which accepts any data type. The input is flexible and can be tailored to the needs of the specific operation.

2. b: This is the second input, similar to input "a", and also accepts any data type.

3. operator: A string input that specifies the boolean or comparison operation to be performed. The available operators include:

   • == (equal to)
   • != (not equal to)
   • > (greater than)
   • < (less than)
   • >= (greater than or equal to)
   • <= (less than or equal to)
   • and (logical AND)
   • or (logical OR)
   • xor (logical XOR)
   • not(a) (logical NOT on input "a")
   • min (minimum of "a" and "b")
   • max (maximum of "a" and "b")

Outputs

The LayerUtility: BooleanOperator node produces a single output:

• output: The output is a boolean value. It represents the result of the boolean or comparison operation performed on the inputs "a" and "b".

Usage in ComfyUI Workflows

Here are some examples of how the LayerUtility: BooleanOperator node can be used within ComfyUI workflows:

1. Conditional Execution: Use the node to determine whether down-stream operations should be executed by checking conditions between workflow variables.

2. Data Filtering: Filter data or inputs based on specific criteria, such as filtering out entries that do not meet a certain threshold.

3. Validation Checks: Ensure data integrity by comparing expected and actual values, and taking action based on the result.

4. Dynamic Calculations: Use comparisons within mathematics-related workflows to decide the course of operations depending on input values.

Special Features or Considerations

• Operator Versatility: The node supports a range of operators, allowing it to handle both logical and mathematical comparisons, making it broadly applicable across different scenarios.

• Flexible Inputs: The ability to handle any data type for inputs "a" and "b" allows this node to be integrated into a wide variety of workflows with different data requirements.

• Logical Operations: With operators like and, or, xor, and not(a), the node can be used in logical decision-making processes to control the flow of operations dynamically based on multiple conditions.

Incorporating the LayerUtility: BooleanOperator node in your ComfyUI projects can help streamline workflows by evaluating conditions and opening up paths for further data manipulation or decision-making.
