  • Method Details

    • service

      public String service()
      Returns the binary name of the service type.
      Returns:
      the binary name of the service type

    • providers

      public List<String> providers()
      Returns the list of the binary names of the providers or provider factories.
      Returns:
      A non-empty and unmodifiable list of the binary names of the providers or provider factories

    • compareTo

      public int compareTo(ModuleDescriptor.Provides that)
      Compares this Provides to another.

      Two Provides objects are compared by comparing the binary name of the service type lexicographically. Where the class names are equal then the list of the provider class names are compared by comparing the corresponding elements of both lists lexicographically and in sequence. Where the lists differ in size, N is the size of the shorter list, and the first N corresponding elements are equal, then the longer list is considered to succeed the shorter list.

      Specified by:
      compareTo in interface Comparable<ModuleDescriptor.Provides>
      Parameters:
      that - The Provides to compare
      Returns:
      A negative integer, zero, or a positive integer if this Provides is less than, equal to, or greater than the given Provides

    • hashCode

      public int hashCode()
      Computes a hash code for this Provides.

      The hash code is based upon the service type and the set of providers. It satisfies the general contract of the Object.hashCode method.

      Overrides:
      hashCode in class Object
      Returns:
      The hash-code value for this module provides

    • equals

      public boolean equals(Object ob)
      Tests this Provides for equality with the given object.

      If the given object is not a Provides then this method returns false. Two Provides objects are equal if the service type is equal and the list of providers is equal.

      This method satisfies the general contract of the Object.equals method.

      Overrides:
      equals in class Object
      Parameters:
      ob - the object to which this object is to be compared
      Returns:
      true if, and only if, the given object is a Provides that is equal to this Provides

    • toString

      public String toString()
      Returns a string describing this Provides.
      Overrides:
      toString in class Object
      Returns:
      A string describing this Provides
