TransformerTrait

Allow to hold a list of sub-transformers and recursively configure their options.

Reference

• Namespace: CleverAge\ProcessBundle\Transformer\TransformerTrait
• Options algorithm:
  • for each element: the key maps to a transformer code, and the value are resolved by the matching transformer
  • note that the key may be followed by # and any digit, to allow multiple transformer of the same type. Example:

transformers:
    transformer_code#1:
        some_options: ~
    transformer_code#2:
        some_options: ~

Usage

• Call TransformerTrait::configureTransformersOptions with your own OptionResolver. You can change $optionName if you want a custom option name
• Call TransformerTrait::applyTransformers with the resolved transformer options (i.e. $options["transformers"]) and the value you want to pass
