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<Character,V>
  
  Returns:
  
  the intended number of keys in this function, or -1 if that number is not available.
- defaultReturnValue
  
  public V defaultReturnValue()
  
  Description copied from interface: Char2ObjectFunction
  
  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 Char2ObjectFunction<V>
  
  Overrides:
  
  defaultReturnValue in class AbstractChar2ObjectFunction<V>
  
  Returns:
  
  the current default return value.
- defaultReturnValue
  
  public void defaultReturnValue(V defRetValue)
  
  Description copied from interface: Char2ObjectFunction
  
  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 Char2ObjectFunction<V>
  
  Overrides:
  
  defaultReturnValue in class AbstractChar2ObjectFunction<V>
  
  Parameters:
  
  defRetValue - the new default return value.
  
  See Also:
  
  Char2ObjectFunction.defaultReturnValue()
- containsKey
  
  public boolean containsKey(char k)
  
  Description copied from interface: Char2ObjectFunction
  
  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 Char2ObjectFunction<V>
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Function.containsKey(Object)
- put
  
  public V put(char k, V v)
  
  Description copied from interface: Char2ObjectFunction
  
  Adds a pair to the map (optional operation).
  Specified by:
  
  put in interface Char2ObjectFunction<V>
  
  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 V get(char k)
  
  Description copied from interface: Char2ObjectFunction
  
  Returns the value to which the given key is mapped.
  Specified by:
  
  get in interface Char2ObjectFunction<V>
  
  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 V getOrDefault(char k, V defaultValue)
  
  Description copied from interface: Char2ObjectFunction
  
  Returns the value associated by this function to the specified key, or give the specified value if not present.
  Specified by:
  
  getOrDefault in interface Char2ObjectFunction<V>
  
  Parameters:
  
  k - the key.
  
  defaultValue - the value to return if not present.
