```
public class ValidatableParameterMap
extends Object
```
A ValidatableParameterMap serves as registry of parameters that can be used to configure a ValidatableParameterMap.
A ParameterMap holds a list of Property instances upon its initialization, therefore acting as a registry of allowed Propertys.
Furthermore, a ValidatableParameterMap supports setting values of its parameters either directly or automatically.
Calling init()} on a given ValidatableParameterMap will change its state to initialized and prevent further modification of its values, effectively making it immutable. It is mandatory to call init() before obtaining values from a ValidatableParameterMap.

- Method Detail
  - emptyInstance
```
public static ValidatableParameterMap emptyInstance()
```
  - builder
```
public static ValidatableParameterMap.Builder builder()
```
    Obtain a builder instance
    
    Returns:
    
    a fresh builder instance
  - populate
```
public ValidatableParameterMap populate(Resource root)
```
    Populate the ValidatableParameterMap with data taken from the Model attached to the given Resource.
    
    Parameters:
    
    root - this Resource needs to be backed by a Model
  - add
```
public ValidatableParameterMap add(StmtIterator it)
```
    Add all remaining Statements from a given StmtIterator to this ValidatableParameterMap
  - add
```
public ValidatableParameterMap add(Property p,
                                   RDFNode node)
```
    Add a Statement to this ValidatableParameterMap by specifying its predicate and object. If the object is not a literal, its subgraph is also added to the Model backing this ValidatableParameterMap by depth-first search. Infinite loops from cyclical subgraphs are prevented by maintaining a set of visited resources.
  - init
```
public ValidatableParameterMap init()
```
    Initializes this ValidatableParameterMap. Initializing effectively disables all writing operations (attempting to write will result in exceptions) and enables all reading operations.
  - listPropertyObjects
```
public Stream<RDFNode> listPropertyObjects(Property p)
```
    Get a stream of objects for the given property.
  - getOptional
```
public Optional<RDFNode> getOptional(Property p)
```
    Get the first object for a given property as an Optional.
  - get
```
public RDFNode get(Property p)
```
    Get the first object for a given property as an Optional.
  - parametrize
```
public Model parametrize(Resource exNode)
```
    Apply the parameters stored in this ValidatableParameterMap to the given Resource representing a Parameterized.
    
    Returns:
    
    the parameter graph for the given Resource
  - getValidationModel
```
public Model getValidationModel()
```
  - createResource
```
public Resource createResource()
```
  - createResource
```
public Resource createResource(String url)
```
  - createLiteral
```
public Literal createLiteral(String s)
```
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
