Interface FieldRemapping

public interface FieldRemapping
A transformation on a record type. Users should not need to directly implement instances of this interface. Instead, they should use the convenience methods provided in RemapFields for constructing transformations.

  • Method Details

    • apply

      RecordTokenType apply(RecordTokenType srcType, Map<String,String> mapping)
      Computes the result of applying the transformation to a record type. A target-to-source mapping is also computed.
      Parameters:
      srcType - the type being transformed
      mapping - a map for holding the inverted field mapping
      Returns:
      the resulting record type

    • getMappings

      List<String> getMappings(String name)
      Gets the fields in the target to which the specified source field is mapped.
      Parameters:
      name - the name of a field in the source record
      Returns:
      the names of fields in the target which correspond to the field. If the field is not mapped to the target, an empty list is returned.
