    - #### MapBindingSet

          public MapBindingSet()

    - #### MapBindingSet

          public MapBindingSet​(int capacity)

      Creates a new Map-based BindingSet with the specified initial capacity. Bindings can be added to this binding set using the `addBinding(java.lang.String, org.eclipse.rdf4j.model.Value)` methods.
      Parameters:
        `capacity` - The initial capacity of the created BindingSet object.

    - #### addBinding

          public void addBinding​(String name,
                                 Value value)

      Adds a binding to the binding set.
      Parameters:
        `name` - The binding's name.
        `value` - The binding's value.

    - #### addBinding

          public void addBinding​(Binding binding)

      Adds a binding to the binding set.
      Parameters:
        `binding` - The binding to add to the binding set.

    - #### removeBinding

          public void removeBinding​(String name)

      Removes a binding from the binding set.
      Parameters:
        `name` - The binding's name.

    - #### clear

          public void clear()

      Removes all bindings from the binding set.

    - #### iterator

          public Iterator<Binding> iterator()

      Description copied from interface: `BindingSet`
      Creates an iterator over the bindings in this BindingSet. This only returns bindings with non-null values. An implementation is free to return the bindings in arbitrary order.

    - #### getBindingNames

          public Set<String> getBindingNames()

      Description copied from interface: `BindingSet`
      Gets the names of the bindings in this BindingSet.

        A set of binding names.

    - #### getBinding

          public Binding getBinding​(String bindingName)

      Description copied from interface: `BindingSet`
      Gets the binding with the specified name from this BindingSet.
      Parameters:
        `bindingName` - The name of the binding.
      Returns:
        The binding with the specified name, or null if there is no such binding in this BindingSet.

    - #### hasBinding

          public boolean hasBinding​(String bindingName)

      Description copied from interface: `BindingSet`
      Checks whether this BindingSet has a binding with the specified name.
      Parameters:
        `bindingName` - The name of the binding.
      Returns:
        true if this BindingSet has a binding with the specified name, false otherwise.

          public Value getValue​(String bindingName)

      Description copied from interface: `BindingSet`
      Gets the value of the binding with the specified name from this BindingSet.
      Parameters:
        `bindingName` - The name of the binding.
      Returns:
        The value of the binding with the specified name, or null if there is no such binding in this BindingSet.

    - #### size

          public int size()
