- Method Detail
  - values
```
public static RelationshipType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (RelationshipType c : RelationshipType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static RelationshipType valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - getSelectorLabel
```
public java.util.Optional<java.lang.String> getSelectorLabel()

    Returns:
    
    Returns the optionally present selector token for this relationship.
  - getDirection
```
public RelationshipDirection getDirection()
```
    Gets the direction of the relationship.
    A RelationshipDirection.DIRECTED direction is formed from a shape that defines a reference to another shape (for example, when a resource defines operations or resources it contains).
    A RelationshipDirection.INVERTED relationship is a relationship from a shape to a shape that defines a relationship to it. The target of such a relationship doesn't define the relationship, but is the target of the relationship.
    
    Returns:
    
    Returns the direction of the relationship.
  - isMemberBinding
```
public boolean isMemberBinding()
```
    Checks if the given relationship connects a container shape to a member.
    
    Returns:
    
    Returns true if a member.
  - isOperationBinding
```
public boolean isOperationBinding()
```
    Checks if the binding is to an operation (create|read|update|delete|put|list|operation|collectionOperation).
    
    Returns:
    
    Returns true if the binding is for any kind of operation binding.
  - isInstanceOperationBinding
```
public boolean isInstanceOperationBinding()
```
    Returns true if relationship connects a resource to an instance operation.
    
    Returns:
    
    True if an instance operation.
  - isCollectionOperationBinding
