Method Detail

test
@Deprecated public boolean test(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:
test
in interfaceChar2BooleanFunction
- Specified by:
test
in interfaceIntPredicate
-
apply
@Deprecated public Boolean apply(Character key)
Deprecated.Please use the corresponding type-specific method instead.This is equivalent to callingFunction.get(Object)
.- Specified by:
apply
in interfaceFunction<Character,Boolean>
- Specified by:
apply
in interfaceFunction<Character,Boolean>
- Parameters:
key
-- Returns:
- See Also:
Function.apply(Object)
,Function.get(Object)
-
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 boolean defaultReturnValue()
Description copied from interface:Char2BooleanFunction
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 interfaceChar2BooleanFunction
- Returns:
- the current default return value.
-
defaultReturnValue
public void defaultReturnValue(boolean defRetValue)
Description copied from interface:Char2BooleanFunction
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 interfaceChar2BooleanFunction
- Parameters:
defRetValue
- the new default return value.- See Also:
Char2BooleanFunction.defaultReturnValue()
-
containsKey
public boolean containsKey(char k)
Description copied from interface:Char2BooleanFunction
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 interfaceChar2BooleanFunction
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Function.containsKey(Object)
-
containsKey
@Deprecated public boolean containsKey(Object k)
Deprecated.Description copied from interface:Char2BooleanFunction
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 interfaceChar2BooleanFunction
- Specified by:
containsKey
in interfaceFunction<Character,Boolean>
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.containsKey(Object)
-
put
public boolean put(char k, boolean v)
Description copied from interface:Char2BooleanFunction
Adds a pair to the map (optional operation).- Specified by:
put
in interfaceChar2BooleanFunction
- 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(char k)
Description copied from interface:Char2BooleanFunction
Returns the value to which the given key is mapped.- Specified by:
get
in interfaceChar2BooleanFunction
- 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 boolean remove(char k)
Description copied from interface:Char2BooleanFunction
Removes the mapping with the given key (optional operation).- Specified by:
remove
in interfaceChar2BooleanFunction
- 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).- Specified by:
clear
in interfaceFunction<Character,Boolean>

in interfaceChar2BooleanFunction
- Specified by:
put
in interfaceFunction<Character,Boolean>
- Parameters:
k
