@PublicApi
public class ExecutionStepInfo
extends java.lang.Object
```
As the graphql query executes, it forms a hierarchy from parent fields (and their type) to their child fields (and their type) until a scalar type is encountered; this class captures that execution type information.
The static graphql type system (rightly) does not contain a hierarchy of child to parent types nor the nonnull ness of type instances, so this helper class adds this information during query execution.

Modifier and Type	Method	Description
`ExecutionStepInfo`	`changeTypeWithPreservedNonNull(GraphQLOutputType newType)`	This allows you to morph a type into a more specialized form yet return the same parent and non-null ness, for example taking a `GraphQLInterfaceType` and turning it into a specific `GraphQLObjectType` after type resolution has occurred
`<T> T`	`getArgument(java.lang.String name)`	Returns the named argument
`java.util.Map<java.lang.String,java.lang.Object>`	`getArguments()`
`MergedField`	`getField()`	This returns the AST fields that matches the `getFieldDefinition()` during execution
`GraphQLFieldDefinition`	`getFieldDefinition()`	This returns the field definition that is in play when this type info was created or null if the type is a root query type
`GraphQLObjectType`	`getObjectType()`	The GraphQLObjectType where fieldDefinition is defined.

    the resolved arguments that have been passed to this field
  - getArgument
```
public <T> T getArgument(java.lang.String name)
```
    Returns the named argument
    
    Type Parameters:
    
    T - you decide what type it is
    
    Parameters:
    
    name - the name of the argument
    
    Returns:
    
    the named argument or null if it's not present
  - getParent
```
public ExecutionStepInfo getParent()
```
    Returns:
    
    the parent type information
  - hasParent
```
public boolean hasParent()
```
    Returns:
    
    true if the type has a parent (most do)
  - changeTypeWithPreservedNonNull
```
public ExecutionStepInfo changeTypeWithPreservedNonNull(GraphQLOutputType newType)
```
    This allows you to morph a type into a more specialized form yet return the same parent and non-null ness, for example taking a GraphQLInterfaceType and turning it into a specific GraphQLObjectType after type resolution has occurred
    
    Parameters:
    
    newType - the new type to be
    
    Returns:
    
    a new type info with the same
