And Condition

This condition allows logical combinations of other conditions.

Available configuration keys: 

• condition: An array of arrays. Each element must have a 'plugin' key that is the id of the condition. Any additional properties will be used as configuration when creating an instance of the condition.

• iterate: (optional) The default value is FALSE. If 'iterate' is FALSE, Each condition is evaluated on the source value. If 'iterate' is TRUE, then each condition is evaluated on the element in the source that has the corresponding index/key. Thus, when 'iterate' is TRUE, the source must be an array.

• negate: (optional) Whether the 'and' condition should be negated. Defaults to FALSE. You can also negate the 'and' plugin by using 'not:and' as the plugin id.

• source: (optional) Property or array of properties on which to evaluate the condition. If not set, the condition will be evaluated on the source passed to the ::evaluate() method, typically the source of the process plugin that is using this condition.

 Examples

1. Set a boolean value is_a_teenager based on source_age

process:
  is_a_teenager:
    plugin: evaluate_condition
    source: source_age
    condition:
      plugin: and
      conditions:
        -
          plugin: not:less_than
          value: 13
        -
          plugin: less_than
          value: 20

2. Set a boolean if a source value is 5.

This is overly complicated. It should really be done with a single equals condition. But it's just an example!

process:
  source_is_five:
    plugin: evaluate_condition
    source: source_value
    condition:
      plugin: and
      conditions:
        -
          plugin: greater_than
          value: 4
        -
          plugin: greater_than
          negate: true
          value: 5
        -
          plugin: callback
          callable: is_int

 3. Set a boolean if the source is large and in charge.

This example demonstrates the iterate property which is only available on logical conditions (and and or).

process:
  large_and_in_charge:
    plugin: evaluate_condition
    source:
      - source_size
      - source_comportment
    condition:
      plugin: and
      iterate: true
      conditions:
        -
          plugin: equals
          value: 'large'
        -
          plugin: equals
          value: 'in charge'

Alternatively, we can configure the source directly on each condition. This is a situation where this strategy leads to simpler code.

process:
  large_and_in_charge:
    plugin: evaluate_condition
    condition:
      plugin: and
      conditions:
        -
          plugin: equals
          value: 'large'
          source: source_size
        -
          plugin: equals
          value: 'in charge'
          source: source_comportment
