  • Method Details

    • containsValue

      public boolean containsValue​(boolean v)
      Description copied from interface: Short2BooleanMap
      Returns true if this map maps one or more keys to the specified value.
      Specified by:
      containsValue in interface Short2BooleanMap
      See Also:
      Map.containsValue(Object)
    • getOrDefault

      @Deprecated public java.lang.Boolean getOrDefault​(java.lang.Object key, java.lang.Boolean defaultValue)
      Deprecated.
      Description copied from interface: Short2BooleanMap
      Returns the value associated by this function to the specified key, or give the specified value if not present.

      This default implementation just delegates to the corresponding Map method.

      Specified by:
      getOrDefault in interface Function<java.lang.Short,​java.lang.Boolean>
      Specified by:
      getOrDefault in interface java.util.Map<java.lang.Short,​java.lang.Boolean>
      Specified by:
      getOrDefault in interface Short2BooleanFunction
      Specified by:
      getOrDefault in interface Short2BooleanMap
      Parameters:
      key - the key.
      defaultValue - the default value to return if not present.
      Returns:
      the corresponding value, or defaultValue if no value was present for the given key.

      Map.getOrDefault(Object, Object)
    • getOrDefault

      public boolean getOrDefault​(short key, boolean defaultValue)
      Description copied from interface: Short2BooleanFunction
      Returns the value associated by this function to the specified key, or give the specified value if not present.
      Specified by:
      getOrDefault in interface Short2BooleanFunction
      Specified by:
      getOrDefault in interface Short2BooleanMap
      Overrides:
      getOrDefault in class Short2BooleanFunctions.EmptyFunction
      Parameters:
      key - the key.
      defaultValue - the value to return if not present.
      Returns:
      the corresponding value, or defaultValue if no value was present for the given key.
      See Also:
      Function.getOrDefault(Object, Object)
    • containsValue

      @Deprecated public boolean containsValue​(java.lang.Object ov)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      containsValue in interface java.util.Map<java.lang.Short,​java.lang.Boolean>
      Specified by:
      containsValue in interface Short2BooleanMap
    • putAll

      public void putAll​(java.util.Map<? extends java.lang.Short,​? extends java.lang.Boolean> m)
      Specified by:
      putAll in interface java.util.Map<java.lang.Short,​java.lang.Boolean>
    • short2BooleanEntrySet

      public ObjectSet<Short2BooleanMap.Entry> short2BooleanEntrySet()
      Description copied from interface: Short2BooleanMap
      Returns a type-specific set view of the mappings contained in this map.

      This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

      Specified by:
      short2BooleanEntrySet in interface Short2BooleanMap
      Returns:
      a type-specific set view of the mappings contained in this map.

      Map.entrySet()
    • keySet

      public ShortSet keySet()
      Description copied from interface: Short2BooleanMap
      Specified by:
      keySet in interface java.util.Map<java.lang.Short,​java.lang.Boolean>
      Specified by:
      keySet in interface Short2BooleanMap
      Returns:
      a set view of the keys contained in this map.

    • values

      public BooleanCollection values()
      Description copied from interface: Short2BooleanMap
      Specified by:
