apply
Deprecated.Please use the corresponding type-specific method instead.This is equivalent to callingFunction.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:Double2BooleanFunction
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 interfaceDouble2BooleanFunction
- Returns:
- the current default return value.
-
defaultReturnValue
public void defaultReturnValue(boolean defRetValue) Description copied from interface:Double2BooleanFunction
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 interfaceDouble2BooleanFunction
- Parameters:
defRetValue
- the new default return value.- See Also:
-
containsKey
public boolean containsKey(double k) Description copied from interface:Double2BooleanFunction
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 interfaceDouble2BooleanFunction
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:

containsKey
Deprecated.Description copied from interface:Double2BooleanFunction
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:

in interfaceDouble2BooleanFunction
- Specified by:
containsKey
in interfaceFunction<Double,
Boolean> - Parameters:

put
public boolean put(double k, boolean v) Description copied from interface:Double2BooleanFunction
Adds a pair to the map (optional operation).- Specified by:
put
in interfaceDouble2BooleanFunction
- 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 boolean get(double k) Description copied from interface:Double2BooleanFunction
Returns the value to which the given key is mapped.- Specified by:
get
in interfaceDouble2BooleanFunction
- 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 boolean getOrDefault(double k, boolean defaultValue) Description copied from interface:Double2BooleanFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceDouble2BooleanFunction
- 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:

Removes the mapping with the given key (optional operation).- Specified by:
remove
in interfaceDouble2BooleanFunction
- Parameters:
k
