public boolean containsKey(Object k)
Function
Note that for some kind of functions (e.g., hashes) this method will always return true.
containsKey
in interface Function<K,Float>
k
- the key.key
.Map.containsKey(Object)
public float getFloat(Object k)
Object2FloatFunction
getFloat
in interface Object2FloatFunction<K>
k
- the key.Function.get(Object)
public int size()
Function
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.
