FieldRemapping (Dataflow Library Distribution Project 8.2.0-176 API)

```
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 Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`RecordTokenType`	`apply(RecordTokenType srcType, Map<String,String> mapping)`	Computes the result of applying the transformation to a record type.
`List<String>`	`getMappings(String name)`	Gets the fields in the target to which the specified source field is mapped.

  - 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.
