apply
@Deprecated public V apply(int operand)
Deprecated.Please use the corresponding type-specific method instead.In this default implementation, the key gets narrowed down to the actual key type, throwing an exception if the given key can't be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. Its use is discouraged, as unexpected errors can occur. Instead, the corresponding classes should be used (e.g.,
Int2IntFunction
instead ofShort2IntFunction
).- Specified by:
apply
in interfaceChar2ObjectFunction<V>
- Specified by:

in interfacejava.util.function.IntFunction<V>

apply
@Deprecated public V apply(java.lang.Character key)
Deprecated.Please use the corresponding type-specific method instead.This is equivalent to callingFunction.get(Object)
.- Specified by:
apply
in interfaceFunction<java.lang.Character,V>
- Specified by:
apply
in interfacejava.util.function.Function<java.lang.Character,V>
- Parameters:
key
-- Returns:
- See Also:

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.
-
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 interfaceChar2ObjectFunction<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 ofget()
,put()
andremove()
to denote that the map does not contain the specified key. It must be 0/false
/null
by default.- Specified by:
defaultReturnValue
in interfaceChar2ObjectFunction<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 interfaceChar2ObjectFunction<V>
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Function.containsKey(Object)
-
containsKey
@Deprecated public boolean containsKey(java.lang.Object k)
Deprecated.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. This default implementation, in particular, always return true.
- Specified by:
containsKey
in interfaceChar2ObjectFunction<V>
- Specified by:
containsKey
in interfaceFunction<java.lang.Character,V>
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.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 interfaceChar2ObjectFunction<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 interfaceChar2ObjectFunction<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)
-
remove
public V remove(char k)
Description copied from interface:Char2ObjectFunction
Removes the mapping with the given key (optional operation).- Specified by:
remove
in interfaceChar2ObjectFunction<V>
- Parameters:
k
- the key.- Returns:
- the old value, or the default return value if no value was present for the given key.
- See Also:
Function.remove(Object)
-
clear
public void clear()
Description copied from interface:Function
Removes all associations from this function (optional operation).
-
put
@Deprecated public V put(java.lang.Character k, V v)
Deprecated.Please use the corresponding type-specific method instead.Associates the specified value with the specified key in this function (optional operation).
-
get
@Deprecated public V get(java.lang.Object k)
Deprecated.Please use the corresponding type-specific method instead.Returns the value associated by this function to the specified key.
-
remove
@Deprecated public V remove(java.lang.Object k)
Deprecated.Please use the corresponding type-specific method instead.Removes this key and the associated value from this function if it is present (optional operation).
