containsKey
public boolean containsKey(double key)
Description copied from interface:Double2ObjectFunction
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 interfaceDouble2ObjectFunction<V>
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Function.containsKey(Object)

- Specified by:
containsKey
in interfaceDouble2ObjectFunction<V>
- Specified by:
containsKey
in interfaceFunction<java.lang.Double,V>
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.containsKey(Object)

get
public V get(double key)
Description copied from interface:Double2ObjectFunction
Returns the value to which the given key is mapped.- Specified by:
get
in interfaceDouble2ObjectFunction<V>
- Parameters:
key
- 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)

getOrDefault
public V getOrDefault(double key, V defaultValue)
Description copied from interface:Double2ObjectFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceDouble2ObjectFunction<V>
- Parameters:
key
- the key.defaultValue
- the value to return if not present.- Returns:

- Specified by:
getOrDefault
in interfaceFunction<java.lang.Double,V>
- Parameters:
key
- the key.defaultValue
- the default value to return if not present.- Returns:
