Method Detail

applyAsDouble
public double applyAsDouble(K operand)
Description copied from interface:Reference2FloatFunction
- Specified by:
applyAsDouble
in interfaceReference2FloatFunction<K>
- Specified by:
applyAsDouble
in interfaceToDoubleFunction<K>
-
apply
@Deprecated public Float apply(K key)
Deprecated.Please use the corresponding type-specific method instead.This is equivalent to callingFunction.get(Object)
.- Specified by:
apply
in interfaceFunction<K,Float>
- Specified by:
apply
in interfaceFunction<K,Float>
- 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 float defaultReturnValue()
Description copied from interface:Reference2FloatFunction
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 interfaceReference2FloatFunction<K>
- Returns:
- the current default return value.
-
defaultReturnValue
public void defaultReturnValue(float defRetValue)
Description copied from interface:Reference2FloatFunction
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 interfaceReference2FloatFunction<K>
- Parameters:
defRetValue
- the new default return value.- See Also:
Reference2FloatFunction.defaultReturnValue()
-
containsKey
public boolean containsKey(Object k)
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. This default implementation, in particular, always return true.
- Specified by:
containsKey
in interfaceFunction<K,Float>
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.containsKey(Object)
-
put
public float put(K k, float v)
Description copied from interface:Reference2FloatFunction
Adds a pair to the map (optional operation).- Specified by:
put
in interfaceReference2FloatFunction<K>
- 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)
-
getFloat
public float getFloat(Object k)
Description copied from interface:Reference2FloatFunction
Returns the value to which the given key is mapped.- Specified by:
getFloat
in interfaceReference2FloatFunction<K>
- 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)
-
removeFloat
public float removeFloat(Object k)
Description copied from interface:Reference2FloatFunction
Removes the mapping with the given key (optional operation).- Specified by:
removeFloat
in interfaceReference2FloatFunction<K>
- 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<K,Float>
- See Also:
Map.clear()
-
put
@Deprecated public Float put(K k, Float v)
Deprecated.Please use the corresponding type-specific method instead.Associates the specified value with the specified key in this function (optional operation).- Specified by:
put
in interfaceFunction<K,Float>
- Specified by:
put
in interfaceReference2FloatFunction<K>
- Parameters:
k
- the key.v
- the value.- Returns:
- the old value, or
null
if no value was present for the given key. - See Also:
Map.put(Object,Object)
-
get
@Deprecated public Float get(Object k)
Deprecated.Please use the corresponding type-specific method instead.Returns the value associated by this function to the specified key.- Specified by:
get
in interfaceFunction<K,Float>
- Specified by:
get
in interfaceReference2FloatFunction<K>
- Parameters:
k
- the key.- Returns:
- the corresponding value, or
null

remove
@Deprecated public Float remove(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).- Specified by:
remove
in interfaceFunction<K,Float>
