Type Parameters:

PAYLOAD - Type of the object to be transformed

CONTEXT - Type used in the accumulator to identify current iteration (e.g., Integer representing idx of mutated char in a string)

public interface Transformer<PAYLOAD,CONTEXT>
```
Returns a generic transformer interface that can be implemented in type-specific classes (e.g., StringTransformer).

  - transform
```
Transformer<PAYLOAD,CONTEXT> transform(PAYLOAD payload,
                                             Accumulator<PAYLOAD,CONTEXT> accumulator)
```
    Returns transformer instance containing the payload after applying the transformation.
    
    Parameters:
    
    payload - Value to be transformed
    
    accumulator - Accumulator of current iteration
    
    Returns:
    
    Transformer
  - hasNext
```
boolean hasNext()
```
    Returns whether current iteration has a successor.
    
    Returns:
    
    boolean
  - getPayloadType
```
java.lang.reflect.Type getPayloadType()
```
    Returns Type of the payload.
    
    Returns:
    
    Type of the payload
  - getAccumulatorType
```
java.lang.reflect.Type getAccumulatorType()
```
    Returns Type representation of the accumulator. This method is used to serialize the accumulator in Gson.
    
    Returns:
    
    Type representation of the accumulator
  - getResult
```
PAYLOAD getResult()
```
    Returns payload after applying the transformation. The transform method should be called at least once before this method.
    
    Returns:
    
    Payload
  - getInitialAccumulator
```
Accumulator<PAYLOAD,CONTEXT> getInitialAccumulator(PAYLOAD referenceValue)
```
    Returns initial accumulator used in the first transformation.
    
    Parameters:
    
    referenceValue - reference value used in the initial accumulator
    
    Returns:
    
    Initial accumulator
  - getInitialAccumulator
```
default Accumulator<PAYLOAD,CONTEXT> getInitialAccumulator()
```
    Returns initial accumulator used in the first transformation. The reference value is null.
    
    Returns:
    
    Initial accumulator
  - getNextAccumulator
```
Accumulator<PAYLOAD,CONTEXT> getNextAccumulator()
```
    Returns accumulator of next transformation.
    
    Returns:
    
    Generic accumulator
