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.
    
    Specified by:
    
    size in interface Function<java.lang.Long,java.lang.Character>
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.

public boolean containsKey(long k)
```
    Specified by:
    
    containsKey in interface Long2CharFunction

  - defaultReturnValue
```
public char defaultReturnValue()
```
    Description copied from interface: Long2CharFunction
    
    Gets the default return value.
    
    Specified by:
    
    defaultReturnValue in interface Long2CharFunction
    
    Overrides:
    
    defaultReturnValue in class AbstractLong2CharFunction
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(char defRetValue)
```
    Description copied from interface: Long2CharFunction
    
    Sets the default return value. 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 Long2CharFunction
    
    Overrides:
    
    defaultReturnValue in class AbstractLong2CharFunction
    
    Parameters:
    
    defRetValue - the new default return value.

    Long2CharFunction.defaultReturnValue()
  - put
```
public char put(long k,
                char v)
```
    Description copied from interface: Long2CharFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Long2CharFunction
    
    Overrides:
    
    put in class AbstractLong2CharFunction
    
    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.

  - clear
```
public void clear()
```
    Description copied from interface: Function

@Deprecated
public char remove(long k)
```
    Deprecated. Please use the corresponding type-specific method instead.
    
    Removes the mapping with the given key.
    
    Specified by:
    
    remove in interface Long2CharFunction
    
    Overrides:
    
    remove in class AbstractLong2CharFunction
    
    Parameters:
    
    k - the key.

```
@Deprecated
public char get(long k)
```
    Deprecated. Please use the corresponding type-specific method instead.
    
    Returns the value to which the given key is mapped.
    
    Specified by:
    
    get in interface Long2CharFunction
    
    Parameters:
    
    k - the key.
    
    Returns:
    
    the corresponding value, or the default return value if no value was present for the given key.

```
public boolean containsKey(java.lang.Object ok)
```
    Description copied from interface: Function
    
    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.
    
    Specified by:
    
    containsKey in interface Function<java.lang.Long,java.lang.Character>
    
    Overrides:
    
    containsKey in class AbstractLong2CharFunction
    
    Parameters:
    
    ok - the key.
