```
public MapState.Builder parameters(String parameters)
```
    Description copied from interface: ParametersBuilder
    OPTIONAL. The value of "Parameters" MUST be a valid JSON document. This field forms the effective input to the Task if present. Values from the input to the state can be interpolated via a JSON path expression. To be interpolated the field name of the JSON object must end in the suffix ".$". See example below.
    Given the following Parameters definition.
```
 
 {
 ...
   "Parameters": {
      "flagged": true,
      "parts": {

         "last3.$": "$.vals[3:]"
      }
   }
 ...
 }
 
 
```
    And suppose that the input to the state is as follows:
```
 
 {
    "flagged": 7,
    "vals": [0, 10, 20, 30, 40, 50]
 }
 
 
```
    Then the effective input to the task will be as follows:
```
 
 {
    "flagged": true,
    "parts": {
       "first": 0,
       "last3": [30, 40, 50]

    This object for method chaining.
  - retrier
```
public MapState.Builder retrier(Retrier.Builder retrierBuilder)

    OPTIONAL. Adds the Catchers to this states catchers. If a single branch fails then the entire map state is considered failed and eligible to be caught.
    
    Parameters:
    
    catcherBuilders - Instances of Catcher.Builder. Note that the Catcher object is not built until the MapState is built so any modifications on the state builder will be reflected in this object.
