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.
-
defaultReturnValue
public double defaultReturnValue()Description copied from interface:Short2DoubleFunction
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 interfaceShort2DoubleFunction
- Overrides:
defaultReturnValue
in classAbstractShort2DoubleFunction
- Returns:
- the current default return value.
-
defaultReturnValue
public void defaultReturnValue(double defRetValue) Description copied from interface:Short2DoubleFunction
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 interfaceShort2DoubleFunction
- Overrides:
defaultReturnValue
in classAbstractShort2DoubleFunction
- Parameters:
defRetValue
- the new default return value.- See Also:
-
containsKey
public boolean containsKey(short k) Description copied from interface:Short2DoubleFunction
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 interfaceShort2DoubleFunction
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
-
put
public double put(short k, double v) Description copied from interface:Short2DoubleFunction
Adds a pair to the map (optional operation).- Specified by:
put
in interfaceShort2DoubleFunction
- 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:
-
get
public double get(short k) Description copied from interface:Short2DoubleFunction
Returns the value to which the given key is mapped.- Specified by:
get
in interfaceShort2DoubleFunction
- Parameters:
k
- the key.- Returns:
- the corresponding value, or the default return value if no value was present for the given key.
- See Also:
-
getOrDefault
public double getOrDefault(short k, double defaultValue) Description copied from interface:Short2DoubleFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceShort2DoubleFunction
- Parameters:
k
- the key.defaultValue
- the value to return if not present.- Returns:
- the corresponding value, or
defaultValue
if no value was present for the given key. - See Also:
-
remove
public double remove(short k) Description copied from interface:Short2DoubleFunction
Removes the mapping with the given key (optional operation).- Specified by:
remove
in interfaceShort2DoubleFunction
- Parameters:
k
- the key.- Returns:
- the old value, or the default return value if no value was present for the given key.
- See Also:
-
clear

put
Deprecated.Please use the corresponding type-specific method instead.Associates the specified value with the specified key in this function (optional operation). -
get
Deprecated.Please use the corresponding type-specific method instead.Returns the value associated by this function to the specified key. -
getOrDefault
Deprecated.Please use the corresponding type-specific method instead.Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceFunction<Short,
Double> - Specified by:
getOrDefault
in interfaceShort2DoubleFunction
- Parameters:
k
- the key.defaultValue
- the default value to return if not present.- Returns:
- the corresponding value, or
defaultValue
if no value was present for the given key. - See Also:
