    • transform

      public <T,​ K> java.util.Map<T,​K> transform​(java.util.Map<T,​K> sourceMap, BeanTransformer beanTransformer)
      Copies all properties from a map to a new one applying the transformation function and mappings defined.
      Type Parameters:
      T - the key object type in the source map
      K - the elem object type in the source map
      Parameters:
      sourceMap - the source map
      beanTransformer - the bean transformer to use for the map elements transformation
      Returns:
      a copy of the source object into the destination object

      Copies all properties from a map to a new one applying the transformation function and mappings defined.
      Type Parameters:
      T - the key object type in the source map
      K - the elem object type in the source map
      R - the key object type in the target map
      V - the elem object type in the target map
      Parameters:

    • withKeyTransformer

      public MapTransformer withKeyTransformer​(FieldTransformer... keyFieldTransformer)
      Initializes the transformer functions to apply on a Map key. The transformer function returns directly the field value.
      Specified by:
      withKeyTransformer in interface MapTransformer
      Parameters:
      keyFieldTransformer - the fields transformer function
      Returns:
      the Transformer instance
    • resetKeyTransformer

      public final void resetKeyTransformer()
      Removes all the configured key transformer.
      Specified by:
      resetKeyTransformer in interface MapTransformer
