Method Detail
-
equals
public boolean equals(Object other)
Description copied from interface:BindingSetCompares a BindingSet object to another object.- Specified by:
equalsin interfaceBindingSet- Overrides:
equalsin classObject- Parameters:
other- The object to compare this binding to.- Returns:
- true if the other object is an instance of
BindingSetand it contains the same set of bindings (disregarding order), false otherwise.
-
hashCode
public final int hashCode()
Description copied from interface:BindingSetThe 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:
hashCodein interfaceBindingSet- Overrides:
hashCodein classObject- Returns:
- A hash code for the BindingSet.
