Switch Operator (Boolean Input)

The Switch Operator (Boolean Input) is a StreamPipes data processor that allows you to route events based on the value of a selected boolean field. You can define multiple "switch cases," each with a specific boolean value (true or false) and a corresponding output value. If the input boolean field matches a case, the defined output value will be added to the event. A default output value is used if no case matches or an error occurs during processing.

Configuration

Input Stream Requirements

This processor requires an input stream with at least one boolean property.

Output Strategy

This processor appends a new field to the event with the processed output value. The name of the output field is switch-output.

Static Properties

• Switch Field: Select the boolean field from the input stream that will be used for the switch condition.
• Output Type: Choose the data type of the output value. Available options are:
  • String
  • Boolean
  • Integer
• Switch Cases: Define the different switch conditions and their corresponding output values. Each switch case consists of:
  • Case Value: The boolean value (true or false) to match against the selected switch field.
  • Output Value: The value to output if this case matches. This value will be converted to the selected Output Type.
• Default Output Value: The value to use if none of the defined switch cases match the input or if an error occurs during processing. This value will also be converted to the selected Output Type.

Example

Let's say you have an event with a boolean field isValid and you want to output a "Status" string based on its value:

Original Event
{ "isValid": true }

Configuration:

• Switch Field: isValid
• Output Type: String
• Switch Cases:
  • Case Value: true, Output Value: Valid Data
  • Case Value: false, Output Value: Invalid Data
• Default Output Value: Unknown

Output Event when isValid is true:

Processed Event
{ "isValid": true, "switch-output": "Valid Data" }

Output Event when isValid is false:

Processed Event
{ "isValid": false, "switch-output": "Invalid Data" }
