Method Details
- size
  
  public int size()
  
  Description copied from interface: Function
  
  Returns the intended number of keys in this function, or -1 if no such number exists.
  Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.
  
  Specified by:
  
  size in interface Function<Double,Boolean>
  
  Returns:
  
  the intended number of keys in this function, or -1 if that number is not available.
- defaultReturnValue
  
  public boolean defaultReturnValue()
  
  Description copied from interface: Double2BooleanFunction
  
  Gets the default return value.
  This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).
  
  Specified by:
  
  defaultReturnValue in interface Double2BooleanFunction
  
  Overrides:
  
  defaultReturnValue in class AbstractDouble2BooleanFunction
  
  Returns:
  
  the current default return value.
- defaultReturnValue
  
  public void defaultReturnValue(boolean defRetValue)
  
  Description copied from interface: Double2BooleanFunction
  
  Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
  
  Specified by:
  
  defaultReturnValue in interface Double2BooleanFunction
  
  Overrides:
  
  defaultReturnValue in class AbstractDouble2BooleanFunction
  
  Parameters:
  
  defRetValue - the new default return value.
  
  See Also:
  
  Double2BooleanFunction.defaultReturnValue()
- containsKey
  
  public boolean containsKey(double k)
  
  Description copied from interface: Double2BooleanFunction
  
  Returns true if this function contains a mapping for the specified key.
  Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.
  
  Specified by:
  
  containsKey in interface Double2BooleanFunction
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- put
  
  public boolean put(double k, boolean v)
  
  Description copied from interface: Double2BooleanFunction
  
  Adds a pair to the map (optional operation).
  
  Specified by:
  
  put in interface Double2BooleanFunction
  
  Parameters:
  
  k - the key.
  
  v - the value.
  
  Returns:
  
  the old value, or the default return value if no value was present for the given key.
  
  See Also:
  
  Function.put(Object,Object)
- get
  
  public boolean get(double k)
  
  Description copied from interface: Double2BooleanFunction
  
  Returns the value to which the given key is mapped.
  
  Specified by:
  
  get in interface Double2BooleanFunction
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  the corresponding value, or the default return value if no value was present for the given key.
  
  See Also:
  
  Function.get(Object)
- getOrDefault
  
  public boolean getOrDefault(double k, boolean defaultValue)
  
  Description copied from interface: Double2BooleanFunction
  
  Returns the value associated by this function to the specified key, or give the specified value if not present.
  
  Specified by:
  
  getOrDefault in interface Double2BooleanFunction
  
  Parameters:
  
  k - 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.

  Function.getOrDefault(Object, Object)
- remove
  
  public boolean remove(double k)
  
  Description copied from interface: Double2BooleanFunction
  
  Removes the mapping with the given key (optional operation).
  
  Specified by:
  
  remove in interface Double2BooleanFunction
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  the old value, or the default return value if no value was present for the given key.
