public FieldVisitor()
```
- Method Detail
  - visitField
```
public static <T> T visitField(com.google.protobuf.Descriptors.FieldDescriptor fieldDescriptor,
                               FieldVisitor<T> visitor)
```
    Applies the visitor to the given field.
  - visitMap
```
protected abstract T visitMap(com.google.protobuf.Descriptors.FieldDescriptor mapField,
                              T keyValue,
                              T valueValue)
```
    Visits a proto map field. Which is represented by a soy map.
  - visitJspbMap
```
protected abstract T visitJspbMap(com.google.protobuf.Descriptors.FieldDescriptor keyField,
                                  T valueValue)
```
    Proto map fields are handled by visitMap(com.google.protobuf.Descriptors.FieldDescriptor, T, T). But before protos had a map type, JSPB had a map_key field annotation that simulated map behavior at runtime. They're still out there, somewhere, so we have to support them.
    TODO(b/70671325): Investigate if we can drop support for this.
    
    Parameters:
    
    keyField - the field of the message that is the key field. guaranateed to be a string
    
    valueValue - the result of evaluating this visitor on the field when interpreted as a scalar.
  - visitRepeated
```
protected abstract T visitRepeated(T value)
```
