    • Method Detail

      • getInstance

        public static BindingSet getInstance()
      • 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.
        Specified by:
        iterator in interface BindingSet
        Specified by:
        iterator in interface Iterable<Binding>
      • getBindingNames

        public Set<String> getBindingNames()
        Description copied from interface: BindingSet
        Gets the names of the bindings in this BindingSet.
        Specified by:
        getBindingNames in interface BindingSet
        Returns:
        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.
        Specified by:
        getBinding in interface 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.
        Specified by:
        hasBinding in interface BindingSet
        Parameters:
        bindingName - The name of the binding.
        Returns:
        true if this BindingSet has a binding with the specified name, false otherwise.
      • getValue

        public Value getValue​(String bindingName)
        Description copied from interface: BindingSet
        Gets the value of the binding with the specified name from this BindingSet.
        Specified by:
        getValue in interface 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()
        Description copied from interface: BindingSet
        Returns the number of bindings in this BindingSet.
        Specified by:
        size in interface BindingSet
        Returns:
        The number of bindings in this BindingSet.
      • equals

        public boolean equals​(Object o)
        Description copied from interface: BindingSet
        Compares a BindingSet object to another object.
        Specified by:
        equals in interface BindingSet
        Overrides:
        equals in class Object
        Parameters:
        o - 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 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.
