  - equals
```
public boolean equals(Object other)
```
    Description copied from interface: BindingSet
    
    Compares a BindingSet object to another object.
    
    Specified by:
    
    equals in interface BindingSet
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    other - The object to compare this binding to.
    
    Returns:
    
    true if the other object is an instance of BindingSet and it contains the same set of bindings (disregarding order), false otherwise.
  - hashCode
```
public final int hashCode()
```
    Description copied from interface: BindingSet
    The hash code of a binding is defined as the bit-wise XOR of the hash codes of its bindings:
    int hashCode = 0; for (Binding binding : this) { hashCode ˆ= binding.getName().hashCode() ˆ binding.getValue().hashCode(); }
    
    Note: the calculated hash code intentionally does not depend on the order in which the bindings are iterated over.
    Specified by:
    
    hashCode in interface BindingSet
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    A hash code for the BindingSet.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
